Abstract

Poly(1-napthylamine) (PNPA) was modified by incorporation of diphenylamine (DPA) to result copolymer film on the indium tin oxide (ITO) coated glass electrode using cyclic voltammetry. Detailed static and dynamic UV-Vis spectroelectrochemical studies were performed on the copolymer films to identify the electrochromic sites corresponding to individual DPA and NPA units. Absorbance-wavelength-potential (AWP) profiles were constructed from the dynamic spectroelectrochemical results to infer the electrochromic sites. The advantages of using AWP profile in the analysis of electrochromic sites are discussed.
