Comparison of optical properties and doping behavior of -[(p-C6H4)mNH]n-(m = 1-4) type polymers
Poly(p-oligophenylene amine)s, -[(p-C 6 H 4 ) m NH] n - (m = 2-4), receive electrochemical and chemical oxidation similar to polyaniline (m = 1). In the electrochemical oxidation (or p-doping) in aqueous media and acetonitrile, the oxidation of the polymer with m = 3 occurs at higher potentials by about 1.0 and 0.6 V, respectively, compared with that of polyaniline.
