摘要
本文以现场透射傅里叶变换-红外光谱及紫外-可见光谱电化学方法,研究了高氯酸四苯基卟啉合锰(Ⅲ)在二氯乙烷溶液中电极氧化还原的机理,发现了红外及紫外—可见光谱电化学的证据,表明该锰(Ⅲ)卟啉的第一步还原反应的电子转移发生在金属中心上,生成锰(Ⅲ)卟啉,而第一步氧化反应是发生卟啉环上,生成锰(Ⅲ)卟啉环阳离子自由基。
In situ optically transparent FT-IR and UV-visihle thin-layer spectroelectrochemistry was carried out for the elucidation of the mechanism of electrode redox reactions of tetra-phenylporphinato-manganese ( Ⅱ )perchlorate in dichloroethane solution. Both IR and UV-visible spectral evidence were found.and it is demonstrated that the first-electron-reduction is metal centered reaction of manganese ( Ⅱ )porphyrin generation and the first-electron -oxidation is porphyrin-centcred reaction of manganese ( Ⅱ )porphyrin it cation fadi-cal formation.
