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
