The post-functionalization of poly(3-hexylthiophene) (P3HT) via various synthetic routes is reported. Well-defined and monofunctionalized ω-thiol-terminated P3HT, ω-carboxylic acid-terminated P3HT, ω-acrylate-terminated P3HT, and ω-methacrylate-terminated P3HT are obtained in high yields through a straightforward procedure. From those, different novel P3HT-based graft copolymers are synthesized following two routes: "grafting onto" and "grafting through" (macromonomer polymerization) methods. The synthesis of three types of graft copolymers is described. Each one has "rod" P3HT-grafted side chains on a "coil" main chain, which can be polyisoprene, poly(vinyl alcohol), or poly(butyl acrylate). Each copolymer is characterized by size-exclusion chromatography and NMR.
通过各种合成途径对聚（3-己基噻吩）（P3HT）进行了后功能化。通过简单的程序，可以高收率获得结构明确且单官能化的ω-巯基封端的 P3HT、ω-羧酸封端的 P3HT、ω-丙烯酸酯封端的 P3HT 和 ω-甲基丙烯酸酯封端的 P3HT。从这些中，通过两种方法：“接枝到”和“通过接枝”（大分子单体聚合）方法，合成了不同的新型基于 P3HT 的接枝共聚物。描述了三种类型的接枝共聚物的合成。每一种都具有“棒状”P3HT 接枝侧链和“线圈”主链，主链可以是聚异戊二烯、聚乙烯醇或聚（丙烯酸丁酯）。每个共聚物都通过尺寸排阻色谱法和 NMR 进行了表征。
