摘要: 应用循环伏安、现场紫外可见光谱和红外光谱电化学技术确认了四(对-硝基)苯基卟啉锰配合物产生不同氧化态锰卟啉的电位及其电子光谱和振动光谱特征,发现卟啉周环上硝基的还原发生在Mn2+还原之后,金属价态变化敏感带出现在1597、1523、1207、825和806cm-1附近。

Abstract: The electrochemical and spectroelectrochemical behaviour of tetrakis(4-nitrophenyl) porphyrin manganese complex was studied by cyclic voltammetry in situ FTIRand UV-visible spectroelectrocliemistry.The obtained conditions of different oxidation states, chracteristics of electronic spectra and molecular vibration spectra of the prophyrin manganese complex were indicated.The reduction of nitrobenzene in porphyrin occured after the reduction of central manganese ion.Sensitive bands for the valence state changes of central manganese ion were found at 1597, 1523, 1207, 835 and 806 cm-1.

Key words: Cyclic voltammetry, UV-visible spectroelectrochemistry, FTIR specroelectrochemistry, Porphyrin manganese complex
