以Herrmann催化剂和三（2-二甲氨基苯基）膦为催化剂前体，成功地进行了2-溴-3-己基噻吩的脱卤缩聚反应，得到了高分子量（M（n）= 30，600，M（w）/M（n）= 1.60）和高区域规整度（98%）的头-尾型聚（3-己基噻吩）（HT-P3 HT），产率几乎为99%。
Dehydrohalogenative polycondensation of 2-bromo-3-hexylthiophene was successful with Herrmann's catalyst and tris(2-dimethylaminophenyl)phosphine as catalyst precursors, giving head-to-tail poly(3-hexylthiophene) (HT-P3HT) with high molecular weight (M(n) = 30,600, M(w)/M(n) = 1.60) and high regioregularity (98%) in almost quantitative yield (99%).
