We present a robust manganese-catalyzed cationic reversible addition-fragmentation chain transfer (RAFT) polymerization induced by visible light. Well-defined poly(vinyl ether)s with controlled molecular weight and molecular weight distributions (MWDs) can be conveniently prepared at room temperature without monomer purification. The commercially available manganese carbonyl bromide is used as the photocatalyst for cationic RAFT polymerization. Moreover, this method has been further applied in both batch and continuous flow systems, providing a visible light induced flow cationic polymerization under mild conditions.
我们提出了一种由可见光引发的锰催化的阳离子可逆加成-断裂链转移（RAFT）聚合。通过可见光诱导，在室温下无需单体纯化，即可方便地制备具有可控分子量和分子量分布（MWD）的聚（乙烯基醚）。商业上可用的二溴化五羰基锰用作阳离子 RAFT 聚合的光催化剂。此外，该方法还进一步应用于间歇和连续流动体系中，在温和条件下提供了可见光诱导的流动阳离子聚合。
