Lu, Zhen;Yang, Hongjie;Fu, Xiaoling;Zhao, Rukai;Zhao, Yulai;Cai, Jingyu;Xiao, Longqiang;Hou, Linxi research published 《 Fully-π conjugated covalent organic frameworks as catalyst for photo-induced atom transfer radical polymerization with ppm-level copper concentration under LED irradiation》, the research content is summarized as follows. Photo-induced atom transfer radical polymerization (ATRP) becomes a significant method for preparing well-defined polymers with pre-designable mol. weight and narrow mol. weight dispersity (M_w/M_n). Herein, a fully-π covalent organic framework (COF) was constructed and served as heterogeneous photocatalyst for photo-induced ATRP under LED irradiation TCPB-DMTA-COF, which was constructed by Knoevenagel polycondensation of 1,3,5-tris(4-cynomethylphenyl)benzene (TCPB) and 2, 5-Dimethoxy-terephthalaldehyde (DMTA) and exhibited remarkable performance in mediating photo-induced ATRP of Me methacrylates with the assist of ppm-level concentration of Cu^II under LED irradiation, producing polymers with high chain-fidelity and low value of M_w/M_n (1.10-1.35). The switch “on/off” experiment exhibits excellent temporal and spatial control toward polymerization system. Compared with TCPB-DMTA-CMP, the high crystallinity and stability of TCPB-DMTA-COF endows high monomer conversion and good recyclability performance for photo-induced ATRP. These results suggest COF can be served as a promising artificial photocatalyst for photo-induced ATRP.

Liu, Xiaosong;Dai, Xinyan;Boyko, Walter;Fleischer, Amy S.;Feng, Gang research published 《 Surfactant-mediated synthesis of monodisperse poly(benzyl methacrylate)-based copolymer microspheres》, the research content is summarized as follows. Polymeric microspheres (MSs) have broad applications. Poly(benzyl methacrylate) (PBzMA) have various important applications, such as optical materials, electrochromatog., and photoresists. However, previous studies on PBzMA were on fabricating bulk polymers or nano-sized (<500 nm) spheres. In this study, by introducing a cationic surfactant, cetyltrimethylammonium bromide (CTAB), into the processing, we were the first to successfully synthesize PBzMA-based (pristine and co-polymer) highly monodisperse microspheres. In the synthesis, poly(vinylpyrrolidone) (PVP) is used as the stabilizer to prevent particle aggregation, and cetyltrimethylammonium bromide (CTAB) is used to assist dispersion polymerization The sizes of PBzMA-based MSs can be tuned between 1.0 and 10.0μm with a high monodispersity by controlling the CTAB and monomer concentrations The morphol., mol. structure, mol. weight distribution, thermal stability, and glass transition behavior of the MS samples are determined Particularly, the glass transition temperature can be tuned continuously and smoothly between 59°C-120°C by adjusting the monomer ratio in the synthesis of the copolymer MSs. This study provides insights into a controlled synthesis of size- and property-tunable polymeric and copolymer MSs for broad applications.

The exptl. and DFT computational studies on the directing ability of chalcogenoether motifs in Pd-catalyzed atroposelective C-H functionalization was presented. The thioether motif was found to be a superior directing group compared to the corresponding ether and selenoether in terms of reactivity and enantiocontrol. Remarkably, DFT calculation provided a predictive model for the optimization of reaction conditions and the interpretation of the origin of enantioselectivity. Both Pd-catalyzed enantioselective C-H olefination and allylation reactions were successfully developed using chiral phosphoric acids as efficient ligands, providing a broad range of axially chiral biaryls in good yields with excellent enantioselectivities. The highly enantio- and diastereoselective construction of polyaryls bearing multiple stereogenic axes, gram-scale reaction and various chem. transformations make this protocol more attractive and significant.

Li, Xiang;Jin, Jianbo;Chen, Pinhong;Liu, Guosheng research published 《 Catalytic remote hydrohalogenation of internal alkenes》, the research content is summarized as follows. Abstract: Primary alkyl halides have broad utility as fine chems. in organic synthesis. The direct halogenation of alkenes is one of the most efficient approaches for the synthesis of these halides. Internal alkenes, in particular mixtures of isomers from refineries, constitute readily available and inexpensive feedstock and are the most attractive starting materials for this synthesis. However, the hydrohalogenation of alkenes generally affords branched alkyl halides; there are no catalytic methods to prepare linear alkyl halides directly from internal alkenes, let alone from a mixture of alkene isomers. Here a report the remote oxidative halogenation of alkenes under palladium catalysis via which both terminal and internal alkenes yield primary alkyl halides efficiently. Engineering pyridine-oxazoline ligands by introducing a hydroxyl group is essential for achieving excellent chemo- and regioselectivity. The catalytic system is also good for the mixture of alkene isomers generated from dehydrogenation of alkanes, providing a window to investigate the high-value utilization of inexpensive alkanes.

Photoinduced electron/energy transfer RAFT (PET-RAFT) polymerization can produce well-defined polymers with spatiotemporal control. Semiconducting graphitic carbon nitride (g-C₃N₄), as a thermally and chem. stable photocatalyst, has accomplished the PET-RAFT method under UV-irradiation and blue-light. However, its catalytic efficiency was decreased by the high recombination rate of photogenerated electron-hole pairs, while the control over polymerization was weakened by the UV-decomposition of RAFT reagents. Herein, a series of Au/g-C₃N₄ composite photocatalysts were facilely prepared by the deposition-precipitation method. Arrangement of Au nanoparticles (NPs) on g-C₃N₄ displayed hot electron injection or plasmon-induced resonance energy transfer, which boosts the generation of active electrons for a broadband PET-RAFT process (460-740 nm). The formation of a Schottky barrier enhanced the carrier migration, as it lowered the charge recombination rate. Such a synergistic effect made Au/g-C₃N₄ outperform Au NPs, g-C₃N₄ and their phys. blend. Furthermore, the effects of the Au content, hole scavenger, chain transfer agent, monomer, solvent, and light-source on the highly efficient PET-RAFT polymerization were studied.

Le, Hong Tho;Goto, Atsushi research published 《 Halogen-bond-driven supramolecular assemblies of quaternary-ammonium-iodide-containing polymers in three phases》, the research content is summarized as follows. Halogen bonding (XB) opens avenues to supramol. assemblies. Here, the authors report XB-driven supramol. assemblies of quaternary ammonium iodide (QAI)-containing polymers in three (solution, surface, and solid) phases. In the solution, QAI-containing block copolymers form unique self-assembly structures such as micrometer-sized giant vesicles (up to 5-μm diameter) and a 1-dimensional (1D) structure with multiple inter-vesicular linkages via XB. Exploiting the temperature dependence of XB strength, external mols. are successfully loaded and unloaded. On the surface, reversible XB crosslinking and decrosslinking of QAI-containing polymer brushes are achieved. The wettability of the polymer brush is finely tuned by the XB crosslinking d. In solid phase, QAI-containing monomers are co-crystallized (assembled) via XB. A polymer sheet is obtained via the solid-phase polymerization of the monomer co-crystal; the sheet enables capture and release of halogen-containing (XB-coordinating) guest mols. and thereby serves as an innovative host material.
