Abstract: The electrochemical characteristics of 5,10,15,20-tctrakis-(4-acctoxyphcnyl)-porphine and its Cu,Zn,Fe,Co,Ni complexes were investigated by Cyclic Voltammctry in CH₂Cl₂-0.1mol/1 TBAP.The heterogeneous electron exchange rate constants of above complexes were also calculated by the Cyclic Voltammctry technique of Nicholson.The experimental results demonstrated that Cu,Zn,Ni arc stable to electrochemical oxidation or reduction of the porphine ring,while Fe,Co undergo the changing of oxidation state.Furthermore the order of the first reduction and oxidaton half wave potential of the metal porphyrins as well as their K_s is proportional to the negative charge in the porphine ring.

Keywords: porphyrin electrochemical reaction electron transfer
