Immobilization of a binuclear ruthenium(III) complex on a gold (111) surface: Observations of proton-coupled electron transfer and electrochemical durability in aqueous media
An oxo-bridged diruthenium(III) complex was immobilized on a Au(111) electrode through the coordination by terminal pyridyl groups of self-assembled monolayer of alkyl chains, and the immobilized complex underwent proton-coupled electron-transfer reactions in a very wide pH range (2-12) with remarkable monolayer durability for multiple potential cycles.
