Regioregular poly(3-hexylthiophene) (P3HT) has been a commonly used p-type semi-conducting material for solution processable organic electronics. To establish a living system of"Negishi-type Catalyst-Transfer Polycondensation" using zincate complex as a synthetic method for well-defined P3HT, the ligands of Ni catalyst were optimized. As a result, a ligand of 1,2-bis(dicyclohexylphosphino)ethane produced P3HTs with highly controlled number average molecular weights (1,700-33,000) and very low D values (1.03-1.17). The polymerization results were strongly influenced by steric hindrance and/or electron-donating ability of the ligands. In addition, we succeeded in the post-polymerization of P3HT and the synthesis of P3HT-b-Poly(3-octadecylthiophene), the latter of which is the first demonstration by NCTP using zincate complex. This methodology could also apply to an electron-deficient monomer containing the naphthalene bisimide group to synthesize an n-type semi-conducting material.

用于溶液可加工有机电子产品的常用P型半导体材料已常用的P型半导体材料。为了建立一个使用锌酸盐复合物作为定义明确的P3HT的合成方法的“ Negishi-Type催化剂转移多浓度”的活体系，优化了Ni催化剂的配体。结果，1,2-双（双己基）乙烷的配体产生的P3HT具有高度控制的平均分子量（1,700-33,000）和非常低的D值（1.03-1.17）。聚合结果受到配体的空间障碍和/或电子抑制能力的强烈影响。此外，我们成功地完成了P3HT的聚合和P3HT-B-POLY（3-二十二烷基噻吩）的合成，后者是NCTP使用锌酸盐复合物的首次演示。该方法也可以应用于含有萘双酰亚胺基的电子缺陷单体，以合成N型半导体材料。
