Cysteamine, which is an inexpensive and non-toxic aminothiol, was successfully employed as a photo-selective chain end transformation agent of iodo-terminated polymer chains (polymer-I). Polymer-I was selectively transformed to hydrogen-terminated (polymer-H) and thiol-terminated (polymer-SH) polymers with and without UV irradiation, respectively. This method is applicable to acrylate polymers. This photo-selective reaction offered a single-step preparation of patterned polymer brushes with SH and H chain end functionalities as a unique application.
半胱胺是一种廉价无毒的氨硫醇，成功地被用作碘端聚合物链（聚合物-I）的光选择性链末端转化剂。聚合物-I 在有无紫外光照射的情况下，分别选择性地转化为氢端（聚合物-H）和巯基端（聚合物-SH）聚合物。该方法适用于丙烯酸酯聚合物。这种光选择性反应提供了一种独特的应用，可一步制备具有 SH 和 H 链末端官能团的图案化聚合物刷。
