摘要： Kelet等[1]研究CoTMAPI催化水制取氢气的反应时指出,活性中心是一价钴卟啉。曹锡章等[2]研究钴卟啉催化CO2电化学还原时指出,活性中心也是一价钴卟啉。然而,不稳定价态的金属卟啉配合物的制备和性质研究较为困难。

Abstract: The electrochemical and spectroelectrochemical behaviour of tetra (α-naphythyl) tetrabenzoporphyrin cobalt complex, TNTBPCo, was studied by cyclic voltammetry, in situ FTIR and in situ UV-V is spectroelectrochemistry. The different oxidation states of the complex were obtained by controlling potential electrolysis at different potentials, and this electronic spectra and molecular vibration spectra were studied. The first and second redox processes of TNTBPCo(Ⅱ) correspond to the centre metal cobalt(Ⅱ) to form TNTBPCo(Ⅲ)+or TNTBPCo(Ⅰ)-. The third reduction step is the addition of one electron to the porphyrin ring. The Soret band of TNTBPCo moves to low wavelength as the oxidation state of the complex decreases. The oxidation state sensitive bands of TNTBPCo were found to be in the 1660, 1476, 1142, 924 and 998 cm-1and these bands shift to low frequency as the oxidation state of the centre metal decreases.

Key words: Tetra-(α-naphythyl)tetrabenzoporphyrin cobalt complex, Cyclic voltammetry, In situ UV-V is spectroelectrochemistry, In situ FTIR spectroelectrochemistry
