Abstract:
A resonant Raman scattering and optical absorption study of self-assembled (PAH-Os/PVS)n and (PAH-Os/GOx)m multilayers was presented. It was found that a single monomolecular layer of PAH-Os deposited on a smooth gold surface shows resonant Raman scattering. The strong Raman resonance was observed around 515 nm and was assigned to a metal-to-ligand charge transfer (MLCT) transition involving the metal complex. The results show a blueshift of the bipyridine modes and quenching of the Raman resonance upon oxidation of the self-assembled layers in an electrochemical cell.
