摘要：

The direct UV-VIS spectroelectrochemical observation of an intermediate present during the anodic oxidation is possible in case of N-(3-sulfopropyl)aniline (NSPA), an aniline derivative containing a sulfoalkyl group at the nitrogen atom. The relatively high stability of the intermediate, derived from NSPA, enables the time-dependent spectral observation of the intermediate on a multi second time scale. The subsequent chemical reaction of this intermediate, leading to a soluble oligomer or polymer product, was observed. The two-step mechanism of electropolymerization of aniline derivatives proposed in the literature was confirmed. The interaction of the NSPA intermediate with aniline was studied; and the copolymerization of both monomers was confirmed. (C) 1998 Elsevier Science Ltd. All rights reserved.
