Abstract
Abstract An electropolymerization of aromatic compounds with amino groups and their derivatives (aniline, N-methyl (or ethyl) aniline, o-phenylenediamine, N,N-dimethylaniline, l-pyrenamine, etc.) led to electroactive or electroinactive polymer films on electrode surfaces. For the electroactive films (i.e., PA, PMA, PEA, PPD and PPA) + , the kinetic parameters (standard rate constant, k°, and anodic transfer coefficient, α a ) characterizing the heterogeneous electron-transfer process at the electrode/film interfaces as well as the apparent diffusion coefficient, D app , for the diffusion-like homogeneous charge-transport process within the films were estimated by normal pulse voltammetry; typically k°: 1 × 10 −5 −6 × 10 −4 cm s −1 , α a : 0.67 - 0.86, D app : 1 × 10 −10 −4 × 10 −8 cm 2 s −1 .
