Conducting poly(o-toluidine) (POT) films have been prepared on indium-tin-oxide (ITO) glass plate by electrochemical, dip-coating and Langmuir-Blodgett (LB) film deposition techniques. The electrochemical and optical properties of poly(o-toluidine) films prepared by different methods have been compared using cyclic voltammetry, UV-visible and Fourier transform infrared spectrophotometry techniques.
