对于 N-(3-磺丙基)苯胺 (NSPA)（一种在氮原子上含有磺烷基的苯胺衍生物），可以对阳极氧化过程中存在的中间体进行直接 UV-VIS 光谱电化学观察。来自 NSPA 的中间体相对较高的稳定性使得能够在多秒时间尺度上对中间体进行时间相关的光谱观察。观察到该中间体随后发生化学反应，产生可溶性低聚物或聚合物产物。证实了文献中提出的苯胺衍生物电聚合的两步机理。研究了NSPA中间体与苯胺的相互作用；并证实了两种单体的共聚。
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.
