摘要：

Manganese phthalocyanine MnPc(Sph)(4) has been synthesized and used to form self assembled monolayers on gold electrodes. The well packed SAM monolayer was characterized by analyzing the blocking of a number of Faradic processes by cyclic voltammetry, evaluating the electrical characteristics of the modified electrode by electrochemical impedance and imaging the modified surface by electrochemical scanning microscopy. Finally, MnPc(SPh)(4)-SAM modified electrode displayed an electrocatalytic behavior toward the oxidation of nitrite.
