采用固相合成法,分别用4,7-二噻基-2,1,3-苯并噻二唑,1,4-二噻基-苯和3,6-二噻基-哒嗪与三联噻吩反应合成了三种三联噻吩与噻吩衍生物共聚物(2a~2c),其结构和电化学性质经UV-Vis,IR,SEM和CV表征。结果表明:与均聚物相比,2a~2c的最大吸收峰无明显红移;氧化电位(0.53~0.51 V)较均聚物负移。
Solid phase synthesis method was used respectively with 4,7-dithiyl-2,1,3-benzothiadiazole, 1,4-dithiyl-benzene and 3,6-dithiopyridazine and tris Thiophene reaction of three kinds of thiophene and thiophene derivatives copolymer (2a ~ 2c), its structure and electrochemical properties by UV-Vis, IR, SEM and CV characterization. The results showed that the maximum absorption peak of 2a ~ 2c showed no red shift compared with that of the homopolymer. The oxidation potential (0.53 ~ 0.51 V) was more negative than that of the homopolymer.
