Abstract

Conductive poly(<i>o</i>-toluidine) polymer has been synthesized by both chemical and electrochemical polymerization methods. The presence of methyl group affects not only the electrochemical polymerization window but also brings about drastic changes in the optical and electronic properties of parent polymer polyaniline. Poly(<i>o</i>- toluidine) (POT) shows multiple colour transition (Yellow → Green → Blue → Violet) on switching the potential between reduced and oxidized state with a better electrochromic response time. The present paper addresses the spectroscopic studies on conductive polyanilines.
