2,2?:5?,2??-Terthiophene undergoes electrochemical copolymerization along with carbazole and in sodium perchlorate/acetonitrile was reported. Electrochromic copolymer based on TTh and 3, 4-ethylenedioxythiophene has been reported. It acts as a monomer precursor for polythiophene and as a dopant for polycarbonate. It may function as a photosensitizer. It also exihibits antifungal activity.
