摘要：

Hydroxymethyl functionalized 3,4-ethylenedioxythiophene (EDOT-MeOH) monomer was synthesized according to a previously reported procedure. Electropolymerization of EDOT-MeOH was performed in acetonitrile (ACN) containing tetrabutylammonium perchlorate (Bu4NClO4) as the supporting electrolyte by chronoamperometry on platinum (Pt) and fluorine-doped tin oxide-coated glass substrates. The resulting conjugated polymer (PEDOT-MeOH) was characterized by cyclic voltammetry and UV–Vis spectrophotometer techniques. The polymer showed a deep HOMO energy level of −5.31 eV with a very low band gap of 1.54 eV. Spectroelectrochemical study revealed that the PEDOT-MeOH has interesting electrochromic properties.
