Abstract: The gold electrodes modified with 2-picolinic acid,nicotinic acid,iso-nicotinic or thiophene were prepared using membrane transfer method.The electrochemistry of di-μ-oxodimanganese 2,2'- bipyridine complex was studied in the acetic acid buffer solution at different modified gold electrodes.It was found that the modifiers which can promote the electrochemical reaction of the complex should be of at least two functional groups.One group can be bound to the electrode surface and the other can form electron transfer pathway between the modifier and the complex through salt bridge or hydrogen bond.In addition,the mechanism of the electrochemical reaction was discussed.

Key words: Di-μ-oxodimanganese 2,2'- bipyridine complex, Nicotinic acid, Iso-nicotinic acid, 2-Picolinic acid
