Abstract
A light-mediated method for the facile removal of polymer end groups that are common to controlled radical polymerization techniques is presented. This metal-free strategy is general, being effective for chlorine, bromine, and thiocarbonylthio moieties as well as a number of different polymer families (styrenic, acrylic, and methacrylic). In addition to solution reactions, this process is readily translated to thin films, where light mediation allows the straightforward fabrication of hierarchically patterned polymer brushes.
摘要
本文提出了一种光介导的方法，可轻松去除可控自由基聚合技术中常见的聚合物端基。这种无金属策略具有通用性，对氯、溴和硫代羰基硫部分以及许多不同的聚合物家族（苯乙烯类、丙烯酸类和甲基丙烯酸类）均有效。除了溶液反应外，该过程还很容易转化为薄膜，其中光介导允许直接制造具有分级图案的聚合物刷。
