Abstract: Three novel 3-[omega-(p-methoxyphenoxy)alkyllthiophene monomers were synthesized and electrochemically polymerized on ITO electrodes by potentiodynamic or potentiostatic methods. Potentiostatic deposition provided films with better stabilities and had smaller quantities of soluble oligomers formed during polymerization. We also observed that derivatives with shorter alkyl chains in the substituted thiophene are difficult to polymerize by electrochemical methods. Spectroelectrochemical characterization of the polymer films obtained showed that their colors depend on the alkyl chain length in the substituted monomer. This demonstrates that the electrochromic behavior of these polymers can be tailored by means of the chemical synthesis of the monomers. The electrochromic properties presented by these new polymers motivate their future application in electrochromic devices. (C) 2004 Elsevier B.V. All rights reserved.
