Radical polymerization via the photoinduced decarboxylation of carboxylic acids was achieved in a two-molecule photoredox system using visible light. In this photoreaction, unique polymers with chain ends derived from amino acids, peptides, sugars, and steroids were obtained under mild conditions. In addition, a two-molecule photoredox system for replacing both electron donor and acceptor, led to selective decarboxylation, facilitating the preparation of block copolymers with different segments.

二分子光氧化还原体系中可见光诱导的脱羧自由基聚合


使用可见光在二分子光氧化还原系统中通过羧酸的光诱导脱羧实现了自由基聚合。在该光反应中，在温和条件下获得了具有源自氨基酸、肽、糖和类固醇的链端的独特聚合物。此外，用于取代电子供体和受体的双分子光氧化还原系统导致选择性脱羧，有利于制备具有不同链段的嵌段共聚物。
