Solid Phase Synthesis of Polythiophene Derivatives

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.
