摘　　要：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。Three copolymers （2a ～ 2c） of 2,2＇ ： 5＇,2＇＇-terthiophene with polythiophene dervatives were prepared via solid-phase synthesis by reaction of 2,2＇ ： 5＇ ,2＇＇-terthiophene with 4,7-dithiophenyl-2,1, 3-benzothiadiazole, 1,4-dithiophenyl-benzene and 3, 6-dithiophenyl-pyridazine, respectively. The structure and electrochemical properties were characterized by UV-Vis, IR, SEM and CV. The results showed that comparing with homopolymer, the maximum absorption peak of2a ～ 2c had no obvious red shift, and the oxidation potential（0.53 ～ 0.51 V） exhibited negative shift.
