提出了一种光介导的方法，用于容易地除去受控自由基聚合技术中常见的聚合物端基。这种无金属策略是通用的，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、丙烯酸和甲基丙烯酸）有效。除了溶液反应，这个过程很容易转化为薄膜，其中光介导允许直接制造分层图案化的聚合物刷。
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.
