    • A process for preparing a regioregular homopolymer or copolymer of 3-substituted thiophene, 3-substituted selenophene, 3-substituted thiazol or 3-substituted selenazol by a) reacting a 3-substituted 2,5-dihalothiophene, 2,5-dihaloselenophene, 2,5-dihalothiazol or 2,5-dihaloselenazol with reactive zinc, magnesium and/or an organomagnesium halide to give an organozinc or organomagnesium intermediate containing one halozinc or one halomagnesium group, b) bringing the organozinc or the organomagnesium intermediate into contact with a Ni(II), Ni(O), Pd(II) or Pd(0) catalyst to initiate the polymerization reaction, and c) polymerizing the organozinc or the organomagnesium intermediate to give a regioregular head-to-tail homopolymer or copolymer of 3-substituted thiophene, 3-substituted selenophene, 3-substituted thiazol or 3-substituted selenazol characterized in that the polymerization reaction is carried out at a temperature rising from a lower temperature T 1 to a higher temperature T 2 during a time t 1 , wherein T 1 is in the range of from - 40 to 5 °C and T 2 is in the range of from -20 to 40 °C, wherein T 2 - T 1 is at least 10 °C and the average rate of increase (T 2 -T 1 )/t 1 is in the range of from 0,05 °C/min to 1 °C/min.
    • 制备3-取代噻吩,3-取代的硒吩,3-取代的噻唑或3-取代的硒吩的区域性均聚物或共聚物的方法,通过以下步骤a)使3-取代的2,5-二卤代噻吩,2,5-二卤代硒吩,2 ,5-二卤噻唑或2,5-二卤代硒唑与反应性锌,镁和/或有机卤化镁反应,得到含有一个卤素或一个卤代镁基团的有机锌或有机镁中间体,b)使有机锌或有机镁中间体与Ni (II),Ni(O),Pd(II)或Pd(O)催化剂以引发聚合反应,和c)使有机锌或有机镁中间体聚合,得到区域性的头 - 尾均聚物或3- 取代噻吩,3-取代硒吩,3-取代噻唑或3-取代硒吩,其特征在于聚合反应在从较低温度T1升高至更高温度T2 dur的温度下进行 时间t1,其中T1在-40至5℃的范围内,T2在-20至40℃的范围内,其中T2-T1至少为10℃,平均增加率 (T2-T1)/ t1的范围为0.05℃/分钟至1℃/分钟。
