摘要：

The electrochemical behaviour of iron phthalocyanine (FePc), adsorbed on high surface area RB carbon electrodes in contact with a 5 M KOH solution, was investigated by means of "in situ" ESR spectroscopy. It was found that the adsorbed states of FePc deposited from different solutions (FePc dissolved either in pyridine, or in chloroform, or in concentrated sulphuric acid) behave very differently. It is particularly interesting to observe that the ESR signal of the centre iron ion shifts greatly with electrode potential. Models of FePc adsorbed states and of the electron transfers involved are discussed. © 1990.
