Preparation and Electrochromic Properties of Polythiophene Derivative Films Based on Oligothiophene Derivative Monomers

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.

Polythiophene Derivative

Electrically conducting poly[E-1,2-(4,4prime-dihexyl-2,2prime-dithienyl)ethylene] was synthesized and structurally characterized by UV-visible, 1H NMR, and FTIR spectroscopy. The head-to-head arrangement of the alkylthiophene dyads directly affects the UV-visible, photoluminescence, and electroluminescence maxima of the polymer. The conductivity of the doped polymer was measured to be ~2 S cm-1 and the stability of the oxidized polymer possessing various dopants was compared. UV-visible irradiation of PDHDTE rendered the films insoluble and photolithography was used to produce micron-size images. FTIR was used to monitor the photoproducts during photolysis of PDHDTE. Mechanisms of photooxidation were proposed, based on the photoproducts observed.Key words: polythiophene derivative, head-to-head dyad, photolithography, photooxidation, electroluminescence.
