Abstract

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.

探索可回收硫化铟锌在聚合物合成中的催化性能：丙烯酸酯的良好可控光 ATRP

在可见光诱导的原子转移自由基聚合（ATRP）过程中，硫化锌铟被用作一种异相可回收光催化剂。研究发现，这种光催化剂可通过氧化淬灭机制催化原子转移自由基聚合，而无需任何添加剂。可以获得转化率高、控制性好的聚合物。动力学研究、光开/关实验和嵌段共聚物合成显示了聚合的 "活"/可控性。该光催化剂可重复使用五次，聚合过程无明显失控。生成的聚合物中未检测到金属残留。这一策略为利用可回收的可见光光催化技术很好地合成聚合物提供了一条新途径。
