Abstract: Three kinds of new electrostatic self-assembled multilayer films were prepared with alternating adsorption of H3PMo12O40 and hemicyanine derivatives, and characterized with UV-visible absorption spectroscopy and cyclic voltammetry. The results show that these films are vertically uniform and electrochemically active with surface-controlled behavior, and the charge transfer may occur between H3PMo12O40 and hemicyanine derivatives in the films. The electron transfer rates of the three films are derived to be 0.0027, 0.0019 and 0.00066 s-1, respectively, which decrease with increasing the thickness of the hemicyanine layers in the films.

Key words: Heteropoly acid, Hemicyanine, Self-assembled film, Cyclic voltammetry, UV-visible spectroscopy
