Zhu, Yifan;Jin, Tao;Lian, Tianquan;Egap, Eilaf research published 《 Enhancing the efficiency of semiconducting quantum dot photocatalyzed atom transfer radical polymerization by ligand shell engineering》, the research content is summarized as follows. Manipulating the ligand shell of semiconducting quantum dots (QDs) has proven to be a promising strategy to enhance their photocatalytic performance for small mol. transformations, such as H₂ evolution and CO₂ reduction However, ligand-controlled catalysis for macromols., which differ from small mols. in penetrability and charge transfer behavior due to their bulky sizes, still remains undiscovered. Here, we systematically investigate the role of surface ligands in the photocatalytic performance of cadmium selenide (CdSe) QDs in light-induced atom transfer radical polymerization (ATRP) by using thiol-based ligands with various polarities and chain lengths. A highly enhanced polymerization efficiency was observed when 3-mercapto propionic acid (MPA), a short-chain and polar ligand, was used to modify the CdSe QDs’ surface, achieving high chain-end fidelity, good temporal control, and a dispersity of 1.18, while also tolerating a wide-range of functional monomers ranging from acrylates to methacrylates and fluorinated monomers. Transient absorption spectroscopy and time-resolved photoluminescence studies reveal interesting mechanistic details of electron and hole transfers from the excited QDs to the initiators and 3-MPA capping ligands, resp., providing key mechanistic insight of these ligand controlled and QD photocatalyzed ATRP processes. The thiolate ligands were found to serve as an efficient hole acceptor for QDs, which facilitates the formation of a charge-separated state, followed by electron transfer from the conduction band edge to initiators and ultimately suppressing charge recombination within the QD.

Zhu, Ren-Man;Yang, Cheng-Lin;Chang, Zi-Xuan;Pan, Cai-Yuan;Zhang, Wen-Jian;Hong, Chun-Yan research published 《 Synchronous Synthesis of Polymeric Vesicles with Controllable Size and Low-Polydispersity by Polymerization-Induced Self-Assembly》, the research content is summarized as follows. The size and size distribution of polymeric nanoparticles have great impact on their physicochem. and biol. properties. Polymerization-induced self-assembly (PISA) has been demonstrated to be an efficient method to fabricate various polymeric nanoparticles, among which polymeric vesicles have attracted great interest due to their unique hollow structure. However, polymeric vesicles with relatively broad size distributions and random size are normally formed, which is problematic for many potential applications. Herein, we report the synthesis of polymeric vesicles with low-polydispersity and controllable size by polymerization-induced self-assembly. A mixed macro RAFT agent of three different poly(ethylene glycol) (PEG_m-CPADB) was used to mediate the RAFT dispersion copolymerization of 7-(2-methacryloyloxyethoxy)-4-methylcoumarin (CMA) and benzyl methacrylate (BzMA), which generated vesicles with low-polydispersity (< 0.1) and controllable size in the scope of sub-100 nm. In comparison, RAFT dispersion copolymerization of CMA and BzMA using a single PEG-CPADB as the macro RAFT agent generated vesicles with adjustable but obviously larger size and broader size distributions (> 0.1). The results demonstrate that the ternary stabilizers play a crucial role in the formation of small and low-polydispersity vesicles.

Zhao, Xin;Wang, Fengliang;Kong, Xiang-Peng;Fang, Ruiqi;Li, Yingwei research published 《 Dual-Metal Hetero-Single-Atoms with Different Coordination for Efficient Synergistic Catalysis》, the research content is summarized as follows. Rationally tailoring the coordination environments of metal single atoms (SAs) is an effective approach to promote their catalytic performances, which, however, remains as a challenge to date. Here, we report a novel misplaced deposition strategy for the fabrication of differently coordinated dual-metal hetero-SAs. Systematic characterization results imply that the as-synthesized dual-metal hetero-SAs (exemplified by Cu and Co) are affixed to a hierarchical carbon support via Cu-C₄ and Co-N₄ coordination bonds. D. functional theory studies reveal that the strong synergistic interactions between the asym. deployed CuC₄ and CoN₄ sites lead to remarkably polarized charge distributions, i.e., electron accumulation and deficiency around CuC₄ and CoN₄ sites, resp. The obtained CuC₄/CoN₄@HC catalyst exhibits significantly enhanced capability in substrate adsorption and O₂ activation, achieving superior catalytic performances in the oxidative esterification of aromatic aldehydes in comparison with the Cu- and Co-based SA counterparts.
