For comparison, traditional free radical was carried out dimethylsulfoxide using 2,2'‐azobis‐(2‐propionitrile) initiator. Furthermore, quantitative conversion monomers during makes these interesting coatings. As expected, photopolymer made is amorphous. Interestingly, contains structures DSC investigation.

Abstract Graphitic carbon nitrides (g‐C 3 N 4 ) possess various benefits as heterogeneous photocatalysts, including tunable bandgaps, scalability, and chemical robustness. However, their efficacy ongoing advancement are hindered by challenges like limited charge‐carrier separation rates, insufficient driving force for photocatalysis, small specific surface area, inadequate absorption of visible light. In this study, boron dopants nitrogen defects synergy introduced into bulk g‐C through the calcination a blend nitrogen‐defective NaBH under inert conditions, resulting in formation BCN nanosheets characterized abundant porosity increased area. These promote intermolecular single electron transfer to radical initiator, maintaining intermediates at low concentration better control photoinduced atom polymerization (photo‐ATRP). Consequently, method yields polymers with dispersity tailorable molecular weights mild blue light illumination, outperforming previous reports on . The heterogeneity enables easy efficient reuse subsequent processes. This study effectively showcases simple alter electronic band structures simultaneously introducing defects, leading high‐performance photo‐ATRP providing valuable insights designing photocatalytic systems solar energy harvesting.

Abstract The photoATRP of methyl acrylate (MA) is investigated using riboflavin (RF) and CuBr 2 /Me 6 TREN as a dual catalyst system under green LED irradiation (λ ≈ 525 nm). Both RF enhanced oxygen tolerance, enabling effective ATRP in the presence residual oxygen. High molar mass polymers (up to M n 129 000 g·mol −1 ) with low dispersity ( Đ ≤ 1.16) are prepared, chain‐end fidelity confirmed through successful chain extension. molecular masses obtained polymer increased linearly conversion showed high initiation efficiency. Mechanistic studies by laser flash photolysis reveal that predominant activator generation mechanism reductive quenching Me (83%, [CuBr ]/[Me TREN] = 1/3 condition), supported polymerization kinetics thermodynamic calculations.
