| ○ | ○ | Article | Spinterface Formation at α-Sexithiophene/Ferromagnetic Conducting Oxide | The inorganic/molecular spinterface is an ideal platform for generating extraordinary spin effects. Understanding and controlling these spin-related effects is mandatory for the exploitation of such interfaces in devices. For this purpose we have investigated the adsorption of alpha-sexithiophene (alpha-6T) on La0.7Sr0.3MnO3 (LSMO) as one of the prototypical material combinations used in organic spintronic devices. Atomic force microscopy (AFM), confocal photoluminescence, X-ray and utraviolet photoelectron spectroscopy, and metastable de-excitation spectroscopy unraveled the structure and the electronic configuration of 6T for various surface coverages. This data set allowed the determination of the characteristic features of occupied states: the band diagram and the work function. Finally, density functional theory enabled us to establish that the spin polarization in 6T molecular orbitals critically depends on the termination layer of LSMO, showing a substantial effect on the MnO-terminated one only. We believe that this research provides important hints for a comprehensive understanding of spinterface effects in general and offers key suggestions for the optimization of 6T/LSMO-based spin devices through the engineering of LSMO termination layer. | Bergenti, Ilaria; Riminucci, Alberto; Graziosi, Patrizio; Albonetti, Cristiano; Benini, Mattia; Toffanin, Stefano; Lopez, Sergio G.; Rakshit, Rajib K.; Singh, Manju; Bentley, Phillip D.; Melchakova, Iuliia A.; Avramov, Pavel, V; Dediu, Valentin A.; Pratt, Andrew | Inst Nanostruct Mat ISMN CNR, I-40129 Bologna, Italy; CSIR Natl Phys Lab, New Delhi 110012, India; Univ York, Dept Phys, York YO10 5DD, N Yorkshire, England; Kyungpook Natl Univ, Dept Chem, Daegu 41566, South Korea | ; Graziosi, Patrizio/D-7543-2011; Riminucci, Alberto/D-7525-2011; Albonetti, Cristiano/H-9943-2014; Toffanin, Stefano/N-7651-2015; DEDIU, Valentin/F-5365-2011; Melchakova, Iuliia/KGM-5967-2024; Bergenti, Ilaria/J-9211-2014; Lopez, Sergio/HOF-6803-2023; Pratt, Andrew/AAW-2609-2021 | 6602614257; 7801332848; 25031245200; 6602166285; 57222615662; 16426609300; 8768009200; 6602249097; 59031874300; 57216913636; 57206720228; 7004322420; 6701425924; 8532623200 | ilaria.bergenti@cnr.it;paul.veniaminovich@knu.ac.kr;andrew.pratt@york.ac.uk; | JOURNAL OF PHYSICAL CHEMISTRY C | J PHYS CHEM C | 1932-7447 | 1932-7455 | 125 | 11 | SCIE | CHEMISTRY, PHYSICAL;MATERIALS SCIENCE, MULTIDISCIPLINARY;NANOSCIENCE & NANOTECHNOLOGY | 2021 | 4.177 | 41.3 | 0.56 | 2025-07-30 | 7 | 8 | INITIO MOLECULAR-DYNAMICS; TOTAL-ENERGY CALCULATIONS; THIN-FILMS; ELECTRONIC-STRUCTURE; CHARGE-TRANSFER; SEXITHIOPHENE; GROWTH; INTERFACE; SURFACES; OLIGOTHIOPHENES | Atomic force microscopy; Excited states; Lanthanum compounds; Manganese oxide; Molecular orbitals; Oxide minerals; Photoelectron spectroscopy; Spin polarization; Strontium compounds; Conducting oxides; Confocal photoluminescences; De-excitations; Electronic configuration; Material combination; Sexithiophenes; Spintronic device; Surface coverages; Density functional theory | English | 2021 | 2021-03-25 | 10.1021/acs.jpcc.0c09713 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Structure and Formation of Luminescent Centers in Light-Up Ag Cluster-Based DNA Probes | Fluorescent beacons based on silver (Ag) clusters for DNA/RNA detection represent a new type of turn-on probe that fluoresces upon hybridization to target nucleobase sequences. Physical-chemical mechanisms of their fluorescence activation still remain poorly understood. We studied in detail the fluorescence activation of dark Ag clusters induced by interactions of Ag-DNA complexes with different DNA sequences. In all cases, the final result depends neither on the location of the precursors (dark clusters) nor on their spectral properties. The reaction of fluorescence activation is a process similar to the growth of fluorescent silver clusters on dsDNA matrices. In both cases, reactants are dark clusters and two adjacent DNA strands. The latter form a double-stranded template for cluster nucleation. We found the optimized structure of a green fluorescent Ag-4(+2) cluster assembled on a C3/C3 DNA dimer in two different ssDNA pairs using QM modeling. The calculated absorption spectra match nicely the experimental ones, which proves the optimized structures. We conclude that apparent fluorescence activation in the studied systems results from reassembling Ag clusters on the new dsDNA template formed upon hybridization with the target. The suggested mechanism of "fluorescence activation" offers a way to design new light-up DNA probes. Two DNA strands making up the dsDNA template providing a high yield of bright Ag clusters can be used as the halves with the "stick" tails hybridizing with the base sequence of the target DNA. In this way, we have designed a light-up Ag cluster probe for beta-actin mRNA. | Reveguk, Zakhar, V; Pomogaev, Vladimir A.; Kapitonova, Marina A.; Buglak, Andrey A.; Kononov, Alexei, I | St Petersburg State Univ, Dept Mol Biophys & Polymer Phys, St Petersburg 199034, Russia; Tomsk State Univ, Dept Phys, Tomsk 634050, Russia; Kyungpook Natl Univ, Dept Chem, Coll Nat Sci, 1370 Sankyuk Dong, Daegu 702701, South Korea; Kyungpook Natl Univ, Green Nano Mat Res Ctr, Coll Nat Sci, 1370 Sankyuk Dong, Daegu 702701, South Korea | Pomogaev, Vladimir/E-5049-2014; Kapitonova, Marina/HSH-4051-2023; Buglak, Andrey/J-8242-2016; Kononov, Alexei/J-4745-2012; Kononov, Alexei/JDC-8986-2023 | 57021929700; 6603016010; 59129816100; 55552760800; 7006804718 | a.kononov@spbu.ru; | JOURNAL OF PHYSICAL CHEMISTRY C | J PHYS CHEM C | 1932-7447 | 1932-7455 | 125 | 6 | SCIE | CHEMISTRY, PHYSICAL;MATERIALS SCIENCE, MULTIDISCIPLINARY;NANOSCIENCE & NANOTECHNOLOGY | 2021 | 4.177 | 41.3 | 1.19 | 2025-07-30 | 19 | 18 | EXCITATION-SPECTRA; SILVER CLUSTERS; FLUORESCENT; EMISSION; GOLD | Chemical activation; Dimers; DNA; Fluorescence; Proteins; Silver compounds; Ag clusters; Base sequences; Chemical mechanism; Cluster nucleation; Luminescent centers; Optimized structures; Silver cluster; Spectral properties; DNA sequences | English | 2021 | 2021-02-18 | 10.1021/acs.jpcc.0c09973 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Water Molecules in Zeolite Y Enhance the Photoluminescent Properties of Its Cesium Lead Bromide Quantum Dots, Na4Cs6PbBr4⁸⁺ | Zeolite Pb,Br,H,Cs,Na-Y was prepared by the reaction of Cs49Na22-Y with PbBr2 in a mixed organic solvent, and the structure of a single crystal of it was determined crystallographically. About 26% of its supercages hold a tetrahedral PbBr42- ion at their centers. Each is surrounded by six Cs+ ions, each of which bridges between the two Br- ions on each edge of the PbBr42- tetrahedron. Each of these four Br- ions also bonds to a Na+ ion near the center of a 6-ring. The result is a Na4Cs6PbBr48+ quantum dot (QD) of symmetry (4) over bar 3m (T-d). The supercage in this zeolite (Si/Al = 1.69) has an average charge of 8.9-, which nearly balances the 8+ charge of this QD. Water molecules in 12-rings bridge (Cs+-H-2 O-Cs+) between QDs in adjacent supercages to form domains of tetrahedrally arranged QDs. Both these QDs and these domains are seen directly by electron microscopy. These QDs, when excited by UV radiation, luminesce sharply at 528 nm (green, FWHM = 17.8 nm). Pb,Br,H,Cs,Na-Y and its luminescence are entirely stable in the atmosphere; the bridging water molecules enhance the luminescence and provide that stability. Structure refinement was done in the space group Fd (3) over barm (a = 24.889(4) angstrom) with the 886 unique reflections for which F-o > 3 sigma(F-o) to the final error index R-1 = 0.077. Its composition was confirmed by energy dispersive X-ray analysis. | Ahmad, Raees; Kim, Joon Young; Park, Gi Beom; Heo, Nam Ho; Seff, Karl | Kyungpook Natl Univ, Coll Engn, Dept Appl Chem, Lab Struct Chem, Daegu 41566, South Korea; Univ Hawaii, Dept Chem, Honolulu, HI 96822 USA | 57805062800; 57280808300; 57205061558; 17136916900; 7004839105 | nhheo@knu.ac.kr; | JOURNAL OF PHYSICAL CHEMISTRY C | J PHYS CHEM C | 1932-7447 | 1932-7455 | 125 | 10 | SCIE | CHEMISTRY, PHYSICAL;MATERIALS SCIENCE, MULTIDISCIPLINARY;NANOSCIENCE & NANOTECHNOLOGY | 2021 | 4.177 | 41.3 | 0.28 | 2025-07-30 | 4 | 4 | SINGLE-CRYSTAL STRUCTURE; PEROVSKITE NANOCRYSTALS; HALIDE PEROVSKITES; ROOM-TEMPERATURE; CDS; ENCAPSULATION; LUMINESCENCE; EFFICIENT; EMISSION; CLUSTERS | Cesium compounds; Crystal structure; Energy dispersive X ray analysis; Ions; Lead compounds; Luminescence; Molecules; Nanocrystals; Semiconductor quantum dots; Single crystals; Ternary alloys; Uranium metallography; Vanadium metallography; X ray diffraction analysis; Zeolites; Error index; Lead bromide; Photo-luminescent properties; Space Groups; Structure refinements; Supercages; Water molecule; Zeolite-Y; Bromine compounds | English | 2021 | 2021-03-18 | 10.1021/acs.jpcc.0c11580 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | Article | Joint Channel Estimation, Training Design, Tx Power Allocation, and Rx Power Splitting for MIMO SWIPT Systems | In this letter, we develop a novel scheme for joint channel estimation, training design, transmit (Tx) power allocation, and receive (Rx) power splitting in multiple-input multiple-output (MIMO) simultaneous wireless information and power transfer (SWIPT) systems, which maximizes the average signal-to-error-plus-noise ratio (SENR) with average harvested energy constraints at the receiver. To solve this challenging design problem, we first convert it into a more tractable form, which enables to derive the optimal solution efficiently. To further lower the required complexity, we also propose a suboptimal solution in a closed form. The performance of the proposed scheme is demonstrated through numerical simulations. | Kim, Byungjo; Kang, Jae-Mo; Kim, Hyung-Myung; Kang, Joonhyuk | Korea Adv Inst Sci & Technol KAIST, Sch Elect Engn, Daejeon 34141, South Korea; Kyungpook Natl Univ, Dept Artificial Intelligence, Daegu 41566, South Korea | byungjo@kaist.ac.kr;jmkang@knu.ac.kr;kimhm@kaist.ac.kr;jhkang@ee.kaist.ac.kr; | IEEE COMMUNICATIONS LETTERS | IEEE COMMUN LETT | 1089-7798 | 1558-2558 | 25 | 4 | SCIE | TELECOMMUNICATIONS | 2021 | 3.553 | 41.4 | 3 | Training; MIMO communication; Channel estimation; Receivers; Resource management; Energy harvesting; Maximum likelihood decoding; boldsymbol Channel estimation; energy harvesting; MIMO; power allocation; power splitting; SWIPT; training design | WIRELESS INFORMATION | English | 2021 | 2021-04 | 10.1109/lcomm.2020.3048963 | 바로가기 | 바로가기 | 바로가기 | ||||||||||
| ○ | ○ | Article | Probability Distribution of a Signal's Peak Time in a Molecular Diffusive Media | The peak time of a received signal in a molecular channel is random and generally assumed to follow the Normal distribution. However, the untested validity of the assumption motivates this letter. Considering an absorbing receiver placed in a free-diffusion molecular communication via diffusion (MCvD) system, we analyze the randomness in terms of the distribution of the peak time using simulated data and define one of the parameters. In addition, we derive the semi-analytical expressions of the distribution by using Poisson and Normal approximations of the absorbed molecules. Through numerical analysis, we evaluate the accuracy of the models and demonstrate that the Poisson model achieves a better fit. The key finding is that the distribution has extreme values resulting in a heavy right-tail and this information can be a useful tool to develop improved channel models. | Shitiri, Ethungshan; Yilmaz, H.

| ○ | ○ | Article | Characterization of optical manipulation using microlens arrays depending on the materials and sizes in organic photovoltaics | Various physical structures have improved light-harvesting and power-conversion efficiency in organic photovoltaic devices, and optical simulations have supported the improvement of device characteristics. Herein, we experimentally investigated how microlens arrays manipulate light propagation in microlens films and material stacks for organic photovoltaics to understand the influence of the constituent materials and sizes of the microlens. As materials to fabricate a microlens array, poly(dimethylsiloxane) and Norland Optical Adhesive 63 were adopted. The poly(dimethylsiloxane) microlens array exhibited higher total transmittance and higher diffuse transmittance, further enhancing the effective optical path and light extinction in material stacks for organic photovoltaics. This resulted in more current generation in an organic photovoltaic device with a poly(dimethylsiloxane) microlens array than in a Norland Optical Adhesive 63 microlens array. The sizes of the microlenses were controlled from 0.5 to 10 mu m. The optical characteristics of microlens array films and material stacks with microlenses generally increased with size of the microlens, leading to a 10.6% and 16.0% improvement in the light extinction and power-conversion efficiency, respectively. In addition, electron and current generation in material stacks for organic photovoltaics were calculated from light extinction. The theoretical current generation matched well with experimental values derived from organic photovoltaic devices. Thus, the optical characterization of physical structures helps to predict how much more current can be generated in organic photovoltaic cells with a certain physical structure; it can also be used for screening the physical structures of organic photovoltaic cells. | Ko, Dongwook; Gu, Bongjun; Ma, Yoohan; Jo, Sungjin; Hyun, Dong Choon; Kim, Chang Su; Oh, Hyeon-Ju; Kim, Jongbok | Kumoh Natl Inst Technol, Dept Mat Sci & Engn, Gumi 39177, South Korea; Kumoh Natl Inst Technol, Dept Energy Engn Convergence, Gumi 39177, South Korea; Kyungpook Natl Univ, Sch Architectural Civil Environm & Energy Engn, Daegu 41566, South Korea; Kyungpook Natl Univ, Dept Polymer Sci & Engn, Daegu 41566, South Korea; Korea Inst Mat Sci KIMS, Dept Adv Funct Thin Films, Chang Won 51508, South Korea; Kumoh Natl Inst Technol, Adv Mat Res Ctr, Gumi 39177, South Korea | Oh, Hyeon-Ju/ABH-2809-2020 | 24479440600; 57193761401; 57215733716; 7101724027; 15834575400; 57201346735; 56362812200; 15762365000 | smju26@kumoh.ac.kr;jbkim@kumoh.ac.kr; | RSC ADVANCES | RSC ADV | 2046-2069 | 11 | 17 | SCIE | CHEMISTRY, MULTIDISCIPLINARY | 2021 | 4.036 | 41.6 | 0 | 2025-07-30 | 2 | 2 | Adhesives; Conversion efficiency; Efficiency; Films; Light extinction; Microlenses; Microoptics; Optical instrument lenses; Photoelectrochemical cells; Photovoltaic cells; Constituent materials; Device characteristics; Optical characteristics; Optical characterization; Organic photovoltaic cells; Organic photovoltaic devices; Organic photovoltaics; Power conversion efficiencies; Organic solar cells | English | 2021 | 2021-03-18 | 10.1039/d0ra09262b | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||||
| ○ | Article | Formation of arsenic clusters in InAs nanowires with an Al2O3 shell | An in-depth understanding of thermal behavior and phase evolution is required to apply heterostructured nanowires (NWs) in real devices. The intermediate status during the vaporization process of InAs NWs in an Al2O3 shell was studied by conducting quenching during in situ heating experiments, using a transmission electron microscope. The formation of As clusters in the amorphous Al2O3 shell was confirmed by analyzing the high-angle annular dark field images and energy-dispersive X-ray spectra. The As clusters existed independently in the shell and were also observed at the end of the InAs pieces obtained after quenching. The formation process of the As clusters was demonstrated from a theoretical perspective. Moreover, an ab initio molecular dynamics simulation (AIMD) was conducted to study the atomic and molecular behaviors. | Kim, In; Choi, Suji; Kwon, Ji-Hwan; Ahn, Sang Jung; Yeom, Min Sun; Lee, Ho Seong; Yi, Seong-Hoon; Kim, Young Heon | Korea Inst Sci & Technol Informat, Ctr Supercomp Applicat, 245 Daehak Ro, Daejeon 34141, South Korea; Korea Res Inst Stand & Sci, 267 Gajeong Ro, Daejeon 34113, South Korea; Kyungpook Natl Univ, 80 Daehak Ro, Daegu 41566, South Korea; Chungnam Natl Univ, Grad Sch Analyt Sci & Technol GRAST, 99 Daehak Ro, Daejeon 34134, South Korea | Kim, Young Dok/ABG-8986-2021; Yi, Seonghoon/HGC-6912-2022; Choi, Suji/AAD-6849-2019; Yeom, Min Sun/GPX-9237-2022 | y.h.kim@cnu.ac.kr; | RSC ADVANCES | RSC ADV | 2046-2069 | 11 | 1 | SCIE | CHEMISTRY, MULTIDISCIPLINARY | 2021 | 4.036 | 41.6 | 1 | English | 2021 | 2021-01-01 | 10.1039/d0ra06505f | 바로가기 | 바로가기 | 바로가기 | ||||||||||||
| ○ | ○ | Article | Hydrogen production by electrochemical reaction using ethylene glycol with terephthalic acid | In this study, ethylene glycol (EG) and terephthalic acid (TPA) were used to generate hydrogen using copper electrodes in an alkaline aqueous solution and the corresponding reaction mechanism was experimentally investigated. Both EG and TPA produced hydrogen; however, TPA consumed OH-, inhibiting the production of intermediary compounds of EG and causing EG to actively react with H2O, ultimately leading to enhanced hydrogen production. In addition, the initiation potential of water decomposition of the EG and TPA alkaline aqueous solution was 1.0 V; when 1.8 V (vs. RHE) was applied, the hydrogen production reached 440 mmol L-1, which was substantially greater than the hydrogen production rate of 150 mmol L-1 during water decomposition. | Kim, Se-Hyun; Woo, Sang-Won; Kim, Chan-Soo; Lee, Sung-Eun; Kim, Tae-Oh | Kumoh Natl Inst Technol, Dept Environm Engn, Gumi 39177, South Korea; Korea Inst Energy Res, Jeju Global Res Ctr, Marine Energy Convergence & Integrat Lab, Jeju, South Korea; Kyungpook Natl Univ, Dept Appl Biosci, Daegu 41566, South Korea; Kumoh Natl Inst Technol, Dept Energy Engn Convergence, Gumi 39177, South Korea | Kim, Hyung/J-5451-2012; Kim, Sehyun/KDN-3343-2024 | 57221673590; 57219210124; 7409872719; 55890041600; 9335312200 | selpest@knu.ac.kr;tokim@kumoh.ac.kr; | RSC ADVANCES | RSC ADV | 2046-2069 | 11 | 4 | SCIE | CHEMISTRY, MULTIDISCIPLINARY | 2021 | 4.036 | 41.6 | 0.37 | 2025-07-30 | 6 | 6 | LI-ION; ALKALINE; OXIDATION; ELECTROOXIDATION; COPPER; ELECTROCATALYSTS; METHANOL; WATER; ELECTROLYSIS; BIOMASS | Aliphatic compounds; Electrodes; Ethylene; Ethylene glycol; Polyols; Copper electrodes; Electrochemical reactions; Enhanced hydrogen productions; Hydrogen production rate; Reaction mechanism; Terephthalic acids; Water decomposition; Hydrogen production | English | 2021 | 2021-01-22 | 10.1039/d0ra10187g | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||

| ○ | ○ | Article | Magnetic polymer bowl for enhanced catalytic activity and recyclability | This work introduces the fabrication of a magnetic polymer bowl for enhanced catalytic activity and recyclability, which involves the synthesis of silica-coated Fe3O4 magnetic clusters, seeded dispersion polymerization using the magnetic clusters, and transformation into a bowl-like structure via a phase separation route. The additional treatment with tannic acid (TA) on the bowls allows the in situ formation of silver nanoparticles (AgNPs) on their surfaces. The openness and larger surface area of the bowls, as compared with those of other structured particles, such as spheres and flowers, enable a considerably higher immobilization of AgNPs, thus leading to an excellent catalytic reduction for 4-nitrophenol (4-NP), methylene blue (MB), and rhodamine B. Furthermore, the strong magnetic response originating from the magnetic clusters inside the bowls endows a good magnetic recovery and an excellent reusability for the repeated reduction of the organic dyes without loss of catalytic activity. | Hong, Sang Gi; Im, Eunmi; Kim, Da In; Jeong, Eun Jin; Kim, Jongbok; Moon, Geon Dae; Hyun, Dong Choon | Kyungpook Natl Univ, Sch Appl Chem Engn, Dept Polymer Sci & Engn, Polymer Nanomat Lab, Daegu 41566, South Korea; Korea Inst Ind Technol, Dongnam Div, Busan 46938, South Korea; Kumoh Natl Inst Technol, Dept Mat Sci & Engn, Gumi 39177, Gyeongbuk, South Korea; Kumoh Natl Inst Technol, Dept Energy Engn Convergence, Gumi 39177, South Korea | 57205726022; 57209220408; 57204061726; 58383573300; 15762365000; 23489708500; 15834575400 | gmoon@kitech.re.kr;dong.hyun@knu.ac.kr; | RSC ADVANCES | RSC ADV | 2046-2069 | 11 | 22 | SCIE | CHEMISTRY, MULTIDISCIPLINARY | 2021 | 4.036 | 41.6 | 0.12 | 2025-07-30 | 2 | 2 | NOBLE-METAL NANOPARTICLES; POLYSTYRENE MICROSPHERES; SILVER NANOPARTICLES; RHODAMINE-B; REDUCTION; 4-NITROPHENOL; PARTICLES; NUCLEATION; SPHERES; GROWTH | Magnetism; Phase separation; Reduction; Reusability; Silica; Silver nanoparticles; 4-nitrophenol (4-NP); Additional treatment; Catalytic reduction; Enhanced catalytic activity; Magnetic recovery; Seeded dispersion polymerization; Silver nanoparticles (AgNps); Structured particles; Catalyst activity | English | 2021 | 2021-04-20 | 10.1039/d1ra00453k | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||||
| ○ | ○ | Article | Microwave-assisted green construction of imidazole-fused hybrid scaffolds using 2-aminobenzimidazoles as building blocks | A class of trinuclear imidazole-fused hybrid scaffolds was constructed by the reaction of 2-(2-bromoaryl)- and 2-(2-bromovinyl)imidazoles with 2-aminobenzimidazoles as building blocks in the presence of a base under microwave irradiation. A nucleophilic aromatic substitution followed by cyclization is proposed as a reaction pathway of this green process. | Kwak, Jung Pyo; Quang Dao, Pham Duy; Yoon, Nam Sik; Cho, Chan Sik | Kyungpook Natl Univ, Dept Appl Chem, 80 Daehakro, Bukgu 41566, Daegu, South Korea; Kyungpook Natl Univ, Dept Text Syst Engn, 80 Daehakro, Bukgu 41566, Daegu, South Korea | Dao, P.

| ○ | ○ | Article | One-pot synthesis for gradient copolymers via concurrent tandem living radical polymerization: mild and selective transesterification of methyl acrylate through Al(acac)3 with common alcohols | A series of gradient copolymers were synthesized by the ruthenium-catalyzed living radical polymerization (LRP) of methyl acrylate (MA) and aliphatic alcohols using aluminum acetylacetonate Al(acac)(3). In this polymerization system, Al(acac)(3) was successfully used not only as an additive for the Ru-catalyzed LRP but also as a catalyst for the selective transesterification of an unsaturated ester monomer in mild conditions in a process known as concurrent tandem living radical polymerization. The resulting MA-based gradient copolymers showed well-controlled molecular weight and distribution in a one-pot reaction and exhibited a well-controlled gradient sequence in their polymer chain. Control of transesterification and the metal-catalyzed living radical polymerization (Mt-LRP) rate varied depending on the concentration of the Al(acac)(3) and the structure of varying alcohols, which were confirmed by H-1 NMR, SEC, and DSC analysis. In particular, this research opens a new synthetic methodology for preparing acrylate-based gradient copolymers via concurrent tandem LRP not limited to the synthesis of methyl methacrylate types of gradient copolymers. | Tam Thi-Thanh Huynh; Kim, Si Eun; Kim, Soon Cheon; Kim, Jin Chul; Park, Young Il; Jeong, Ji-Eun; Yeo, Hyeonuk; Lee, Sang-Ho | Korea Res Inst Chem Technol, Ctr Adv Specialty Chem, Ulsan 44412, South Korea; Kyungpook Natl Univ, Dept Sci Educ, Daegu 41566, South Korea; Kyungpook Natl Univ, Dept Pharm, Dept Chem Educ, Daegu 41566, South Korea | Lee, Sang-Ho/T-3699-2019; Yeo, Hyeonuk/AHE-0397-2022; yeo, hyeonuk/G-7890-2017 | 59284707100; 57219449997; 57196401694; 56805502600; 55494480300; 56330436800; 55324816500; 58743026900 | yeo@knu.ac.kr;slee@krict.re.kr; | RSC ADVANCES | RSC ADV | 2046-2069 | 11 | 42 | SCIE | CHEMISTRY, MULTIDISCIPLINARY | 2021 | 4.036 | 41.6 | 0 | 2025-07-30 | 1 | 1 | BLOCK-COPOLYMERS; METHACRYLATE; CATALYST; DESIGN | Acrylic monomers; Aluminum compounds; Atom transfer radical polymerization; Catalysis; Esters; Transesterification; Unsaturated polymers; Aluminum acetylacetonate; Controlled molecular weight; Gradient copolymers; Living radical polymerization; Methyl methacrylates; Polymerization systems; Synthetic methodology; Unsaturated esters; Living polymerization | English | 2021 | 2021-08-10 | 10.1039/d1ra04595d | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||

| ○ | ○ | Article | Synthesis, structures, and catalytic efficiency in ring opening polymerization of rac-lactide with tridentate vs. bidentate cobalt(ii), zinc(ii), and cadmium(ii) complexes containing N-substituted N,N-bis((3,5-dimethyl-1H-pyrazol-1-yl)methyl)amine ligands | A series of Co(ii), Zn(ii), and Cd(ii) complexes supported by 1-(3,5-dimethyl-1H-pyrazol-1-yl)-N-((3,5-dimethyl-1H-pyrazol-1-yl)methyl)-N-(furan-2-ylmethyl)methanamine (L-A) and N,N-bis((3,5-dimethyl-1H-pyrazol-1-yl)methyl)-4-isopropylaniline (L-B) were synthesized. The direct chelation of CoCl2 center dot 6H(2)O, ZnCl2, and CdBr2 center dot 4H(2)O by the ligands produced [LnMX2] (L-n = L-A or L-B; M = Zn or Co, with X = Cl; M = Cd, with X = Br) complexes in high yields. Structural studies revealed that [LBCoCl2] and [LBZnCl2] adopted distorted tetrahedral geometries, as L-B coordinated the metal centers in a bidentate fashion, while L-A coordinated the metal centers in a tridentate fashion through the nitrogen atoms of the pyrazole and amine moieties, so that [LACoCl2] and [LAZnCl2] exhibited trigonal bipyramidal geometries and [LACdBr2] a square pyramidal geometry. [LBCdBr2] has two Cd-containing structures per unit cell, whereby one Cd center adopted a distorted tetrahedral geometry and the other exhibited square bipyramidal geometry. The in situ-generated alkyl derivatives of the synthesized complexes were assessed in the ring-opening polymerization of rac-lactide. Heterotactic polylactides (PLAs) were furnished with all complexes. The [LBZnCl2]/MeLi system produced PLA with a superior heterotactic bias (P-r up to 0.94) at -25 degrees C. PLAs with wide-ranging polydispersity indices (1.16-2.23) and low molecular weights were produced in all cases, irrespective of the specific M(II) center and ancillary ligand utilized. | Choe, Solhye; Lee, Hyosun; Nayab, Saira | Kyungpook Natl Univ, Dept Chem, Daegu 41566, South Korea; Kyungpook Natl Univ, Green Nano Mat Res Ctr, Daegu 41566, South Korea; Shaheed Benazir Bhutto Univ, Dept Chem, Sheringal Dir U, Khyber Pakhtunk, Pakistan | ; Nayab, Saira/JBS-3013-2023 | 57217147488; 15750846000; 36490286400 | hyosunlee@knu.ac.kr;drnayab@sbbu.edu.pk; | RSC ADVANCES | RSC ADV | 2046-2069 | 11 | 31 | SCIE | CHEMISTRY, MULTIDISCIPLINARY | 2021 | 4.036 | 41.6 | 0.37 | 2025-07-30 | 7 | 7 | HETEROTACTIC-ENRICHED POLYLACTIDE; METHYL-METHACRYLATE; METAL-COMPLEXES; EPSILON-CAPROLACTONE; PRE-CATALYSTS; TETRAHEDRAL CHARACTER; MOLECULAR-STRUCTURE; ALKOXIDE COMPLEXES; POLY(LACTIC ACID); INDIUM COMPLEXES | Aromatic compounds; Chelation; Cobalt compounds; Geometry; Ligands; Ring opening polymerization; Synthesis (chemical); Zinc chloride; Bipyramidal geometries; Catalytic efficiencies; Distorted tetrahedral geometries; Low molecular weight; Polydispersity indices; Square-pyramidal geometry; Structural studies; Trigonal bipyramidal geometry; Cadmium compounds | English | 2021 | 2021-06-05 | 10.1039/d1ra02365a | 바로가기 | 바로가기 | 바로가기 | 바로가기 |
