Zinc indium sulfide has been used as a heterogeneous recyclable photocatalyst in visible light-induced atom transfer radical polymerization (ATRP). The photocatalyst was found to catalyze ATRP via an oxidative quenching mechanism without any additives. Polymers in high conversion and good control can be obtained. The kinetic study, light on/off experiment and the block copolymer synthesis showed the “living”/controlled nature of the polymerization. The photocatalyst can be reused for five times without obvious loss of control in the polymerization. Metal residue was not detected in the resulting polymers. This strategy provides a noval way for well-controlled polymer synthesis using recyclable visible light photocatalysis.

探索可回收硫化锌在聚合物合成中的催化性能：丙烯酸酯的光 ATRP 控制良好


硫化锌铟已被用作可见光诱导原子转移自由基聚合 （ATRP） 中的非均相可回收光催化剂。发现光催化剂通过氧化淬灭机制催化 ATRP，无需任何添加剂。可以获得高转化率和良好控制的聚合物。动力学研究、轻开/关实验和嵌段共聚物合成显示了聚合的“活”/受控性质。光催化剂可以重复使用 5 次，而不会在聚合过程中明显失控。在所得聚合物中未检测到金属残留物。该策略为使用可回收可见光光催化进行良好控制的聚合物合成提供了一种新方法。
