Abstract

Two types of sol-gel derived redox modified electrodes are introduced. Anthraquinone modified silicate films were produced from 1,5-di-[(3-trimethoxysilyl)propylamino)anthraquinone derived sol by dip-coating of ITO coated microscope slides. The monomer was synthesized from commercially available 3-aminopopyltrimethoxysilane and 1,5-dichloroanthraquinone. Prussian blue modified electrodes were produced by cycling the potential of a preformed, porous Fe²⁺ doped silicate film coated on ITO substrate in a potassium ferricyanide solution. In both cases, cyclic voltammetry and electronic spectra of the films show that more than 100 layers of redox monomers are electrochemically active, which indicates long range charge transport by electron self exchange mechanism.
