摘　　要：在室温下,首次采用新型聚噻吩衍生物3,6-二噻基-哒嗪,1,4-二噻基-苯和4,7-二噻基-2,1,3-苯并噻二唑分别与2,1,3-苯并硒二唑(BS)通过固相反应制得共聚物。并以FT-IR,UV-Vis,SEM,循环伏安等测试对共聚物进行表征。结果表明:共聚物紫外-可见吸收光谱的最大吸收峰较均聚物有红移,说明共轭链节增长,共轭性能变好。共聚物无特殊形貌。循环伏安测试表明,此三种共聚物均具有较好的电化学活性。The copolymer I of 3,6-dithiophenyl-pyridazine and 2,1,3-benzoselenadiazole, the copolymer Ⅱ of 1,4-dithiophenyl-benzene and 2,1,3-benzoselenadiazole, the copolymer Ⅲ of 4,7-dithiophenyl-2,1,3-benzothiadiazole and 2,1, 3-benzoselenadiazole were firstly prepared by a novel solid-state reaction method at room temperature and were characterized. The SEM images showed that copolymers had no especial sructure. The UV-vis showed that the maximal absorbance of copolymers were all Einstein shift, which illuminated that the chain unit of conjugate was increased and the capability of conjugate become better. These copolymers prepared by the method had good electrochemical properties.
