运用循环伏安法、电化学现场共振拉曼光谱技术和紫外一可见反射光谱技术研究了邻苯二胺导电聚合物（P－o－PD）膜在酸性溶液中的氧化还原过程．循环伏安实验结果表明：聚邻苯二胺的氧化还原过程受表面过程控制，并且在该过程中存在3种稳定的氧化还原态．现场共振拉曼光谱结果证实存在具有不同的结构和稳定性的3种稳定态，并明确指出聚邻苯二胺是一种以吩嗪环为主要结构单元的梯形聚合物．3种状态的P－o-PD表现出不同的紫外-可见光谱特点．进一步用现场时间分辨紫外可见光谱技术研究聚邻苯二胺氧化还原的动态过程，提出了聚邻苯二胺可能的氧化还原机理．
The redox process of o-phenylenediamine conductive polymer (P-o-PD) film in acidic solution was studied by cyclic voltammetry, electrochemical field resonance Raman spectroscopy and UV-Visible reflectance spectroscopy. The results of cyclic voltammetry show that the redox process of poly-o-phenylenediamine is controlled by the surface process, and there are three kinds of stable redox states in the process. In-situ resonance Raman spectroscopy confirmed the presence of three stable states with different structures and stability, and clearly pointed out that poly-o-phenylenediamine is a ladder polymer with phenazine ring as the main structural unit. The 3 states of P-o-PD show different UV-Vis spectral characteristics. Furthermore, the dynamic process of redox polymerization of poly-o-phenylenediamine was further studied by on-site time-resolved UV-Vis spectroscopy, and the possible redox mechanism of poly-o-phenylenediamine was proposed.
