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. View Full-Text
