Preparation and Electrochromic Properties of Polythiophene Derivatives


Article Preview

Polythiophene derivatives, poly(2,2′:5′,2″:5″,2″′:5″′,2″″-quinquethiophene) (P5T), poly (2,3,4,5-tetrathiopenyl-thiophene) (PX5T) and poly(1,3,5-tristhienyl-benzene) (P3TB), were prepared via the electropolymerization. The electrochromic properties of polythiophene derivative films were investigated. The results showed that P5T, PX5T and P3TB films exhibited reversible, clear colour change in liquid electrolyte on electrochemical doping and dedoping. Moreover, solid state electrochromic device, indium tin oxide (ITO)/polythiophene derivative films/conducting gel /ITO, were fabricated with polythiophene derivative films as the active electrochromic layer. The color change of polythiophene derivative films based on gel electrolyte on electrochemical doping and dedoping were similar with the color change based on liquid electrolyte.
