The reduction and oxidation behaviour in alkaline solution of 3,7,13,17-tetramethyl-2,8,12,18-tetrabutylporphyrin (L) has been studied by cyclic voltammetry. The shape of I-E curves was investigated at different terminal values of electrode potential and at different scan rates. It was shown that it is possible to obtain two reversible one-electron electroreduction processes accompanied by the formation of mono- and dianion forms of the porphyrin under specific experimental conditions. The reduction potentials of the L↔L- and L-↔L2- processes are –0.67±0.02 V and –1.12±0.02 V, respectively.
采用循环伏安法研究了3,7,13,17-四甲基-2,8,12,18-四丁基卟啉(L)在碱性溶液中的还原和氧化行为。研究了不同电极电位终值和不同扫描速率下的 I-E 曲线形状。结果表明,在特定的实验条件下,可以获得两个可逆的单电子电还原过程,同时形成卟啉的单阴离子和双阴离子形式。 L↔L-和L-↔L2-过程的还原电位分别为–0.67±0.02 V和–1.12±0.02 V。
