Abstract
In this paper, we review our recent works on the preparations of some Au electrodes modified with self-assembled monolayers of functional metal complexes. such as molecular recognition, electron transfer, bacteria immobilization, and dioxygen activation, from the viewpoint of the construction of chemical/energetic conversion devices. (i) A new-classed promoter electrode bearing optically-active CoIII complexes containing (S)-/(R)-phenylalaninc derivative ligands as the molecular recognition site has been constructed: the chirality and/or orientation of promoter on Au electrode surface have affected the electron transfer rate of cytochrome c. (ii) The FelII-artificial siderophore-modified Au electrode surface has been prepared as an immobilizing tool of microorganisms toward the bacteria sensor and bio-reactor, whose adsorption ability for microorganisms has been studied. (iii) For a purpose of fixation and activation of dioxygen at room temperature, the self-assembled monolayer of dinuclear iron complex has been modified on Au electrode, and its reaction with dioxygen has been studied.
