Well-defined poly(2,5-dihexyloxyphenylene-1,4-diyl) (PPP) is successfully synthesized by the Negishi catalyst-transfer polycondensation (NCTP) using dilithium tetra(tert-butyl)zincate ( Bu ZnLi ). The obtained PPP possesses the number-averaged molecular weight (M ) values in the range of 2100-22 000 and the molar-mass dispersity (Ð ) values in the range of 1.09-1.23. In addition, block copolymers containing PPP and poly(3-hexylthiophene) (P3HT) segments (PPP-b-P3HT) are synthesized to confirm the feasibility of chain extension between the different monomers based on NCTP.
通过使用四（叔丁基）锌酸二锂（BuZnLi）的根岸催化剂转移缩聚反应（NCTP）成功合成了结构明确的聚（2,5-二己氧基亚苯基-1,4-二亚基）（PPP）。所获得的PPP的数均分子量（M）值在2100至22000范围内，摩尔质量分散度（Ð）值在1.09至1.23范围内。此外，合成了含有PPP和聚（3-己基噻吩）（P3HT）链段的嵌段共聚物（PPP-b-P3HT），以确认基于NCTP的不同单体之间链增长的可行性。
