摘要
用循环伏安法研究了氯合四-间甲基卟啉铁[Fe(Ⅲ)T(m-CH3)PPCl],间位取代四苯基卟啉锌[Zn(Ⅱ)T(m—x)PP,x=CH3,H,OCH3,Cl,NO2]的电化学性质,研究了取代基效应,轴向配体影响以及电子转移速率常数.着重讨论了轴向配体与Fe(Ⅲ)T(m-CH3)PPCl竞争配位的反应机理.
lectrochemical characterization of Zn (Ⅱ ) T (m - x)PP (x =-CH3, - H, -OCH3, -Cl, - NO2) and Fe (Ⅲ ) T (m-CH3 ) PPCl were investigated by the technique of cyclicvoltammetry. The effect of substituents on the electrode reaction of Zn(Ⅱ) T(m-x) PP,the effect of axial ligands on the electrode reaction of Fe (Ⅲ) T (m-CH3)PPCl, and thestandard rate constant of electron transfer have been studied. The mechanism of competition coordination of axial ligands with Fe(Ⅲ )T(m-CH3)PPCl were discussed emphasisly.
