    Project supported by the National Natural Science Foundation of China(Nos.20674022,20774031 and 21074039),Doctoral Fund of Ministry of Education of China(No.20090172110011)and Science and Technology Project of Guangdong Province of China(Nos.2006A10702003,2009B090300025 and 2010A090100001).

合成了两种低聚噻吩衍生物单体:2,3':4',2'-三噻吩(I3T)和5,5'-二醛基-2,3':4',2''-三噻吩(OHC-I3T-CHO).通过电化学方法对单体I3T和OHC-I3T-CHO进行了聚合,制备了相应的聚噻吩衍生物.研究了聚噻吩衍生物薄膜的电致变色性能.当外加一定电压时,基于单体I3T的聚噻吩衍生物薄膜可以在淡黄色和淡蓝色之间发生可逆的颜色变化,基于单体OHC-I3T-CHO的聚噻吩衍生物薄膜能在红色和墨绿色间发生可逆的颜色变化.

Oligothiophene derivative monomers,2,3':4',2'-terthiophene(I3T)and 5,5''-biformyl-2,3':4',2''-terthiophene(OHC-I3T-CHO),were synthesized.The corresponding polythiophene derivatives based on I3T and OHC-I3T-CHO monomers were prepared by electropolymerization.The electrochromic properties of polythiophene derivative films were investigated.When the voltage were applied between the ITO working electrode and the platinum wire counter electrode,the I3T film showed reversible,clear color changes from light yellow to light blue,while the OHC-I3T-CHO film showed reversible,clear color changes from red to greenish black.

Key words: oligothiophene derivative monomer, electropolymerization, polythiophene derivative film, electrochromic property
