【Abstract】 Polyoxometalates (POMs) are a kind of attractive building blocks for functional materials because of their unique structure and outstanding properties. Hemicyanines having D-π-A structure are a class of important organic molecules which were extensively investigated because of their multifunctionality. Here, an electrostatically self-assembled film based on a vanadium-substituted tungstoborateand and a hemicyanine cation of (E)-1,1’-(propane-1,3-diyl)bis(4-(4-(dimethylamino)styryl)pyridinium) bromide (H3 ) has been fabricated by Decher’s technique. The UV visible spectra showed that the film was uniformly deposited and H3 molecules formed J-aggregates in the films. As irradiated with white light, the film gave stable cathodic photocurrent.
