Solid Phase Synthesis of Polythiophene Derivatives

摘要: 采用固相法在室温下制备了3,6二噻基哒嗪与1,4二噻基苯的共聚物(Ⅰ)、3,6二噻基哒嗪与4,7二噻基2,1,3苯并噻二唑的共聚物(Ⅱ)和4,7二噻基2,1,3苯并噻二唑与1,4二噻基苯的共聚物(Ⅲ)。并以FTIR、UVVis、SEM、循环伏安等测试手段对上述产物进行了表征。结果表明：这3种新型共聚物有出现层状结构的趋势，厚度达到微米级，并且均具有较好的电化学活性。

Abstract: The copolymers of 3,6dithiophenylpyridazine with 1,4dithiophenylbenzene(Ⅰ), 3,6dithiophenylpyridazine with 4,7dithiophenyl2,1,3benzothiadiazol (Ⅱ) and 4,7dithiophenyl2,1,3benzothiadiazole with 1,4dithiophenylbenzene (Ⅲ) were prepared by solid phase synthesis method at room temperature and were characterized by FTIR, UVVis, SEM and cyclic voltammogram. The SEM images reveal that these three polymers are prone to form samdwish structure with microparticals clusters and show good electrochemical activities.
