Abstract

A dinuclear ruthenium complex [Ru₂(dhpta)(μ-O₂CCH₃)₂]⁻ (H₅dhpta = 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 acetate in the complex by terminal benzoate in a self-assembled monolayer with 4-(6-mercaptohexoxy)benzoic acid. The accumulated complex, which shows a surface redox couple corresponding to Ru^IIIRu^III/Ru^IIIRu^II, covers the gold surface completely. The ligand substitution reaction is applicable for the accumulation of other complexes and useful for the designing of functional electrodes.
