Signal amplification has been demonstrated with surface-bound electrochromic complexes that can exist in one of two oxidation states (M(2+/3+)). Reaction of FeCl(3) with covalently immobilized Os(2+) complexes on glass substrates converts the metal centers. from one oxidation state to the other. The formed Fe(2+) reduces a series of Ru(3+)-based monolayers. The absorption of light is coupled with the oxidation state of the complexes and provides the Output for the monolayer-based device. The gain of the setup can be controlled by the addition of a Fe(2+) chelating ligand.
