Abstract
A dinuclear ruthenium complex [Ru-2(dhpta)(mu-O2CCH3)(2)](-) (H(s)dhpta = 1 ,3-diamino-2-hydroxypropane-N,N,N', N'-tetraacetic acid) is accumulated on a gold surface by using the ligand substitution reaction of bridging acetat e in the complex by terminal benzoate in a self-assembled monolayer with 4- (6-mercaptohexoxy)benzoic acid. The accumulated complex, which shows a surf ace redox couple corresponding to (RuRuIII)-Ru-III/(RuRuII)-Ru-III, covers the gold surface completely. The ligand substitution reaction is applicable for the accumulation of other complexes and useful for the designing of fu nctional electrodes.
