A new inorganic-organic hybrid self-assembled film was prepared by alternative adsorption of polyoxometalate (K10P2W18Cd4(H2O)2O68) and dipolar hemicyanine dye (H6) and studied by UV-Vis spectroscopy and photoelectrochemistry. The film was uniformly deposited with controllable layer number, red-shifted visible absorption band, and stable and large photoelectric signal. The effects of bias voltages, electron donor and electron acceptor on the photocurrent generation were discussed.

Key words: hemicyanine, polyoxometalate, self-assembled film, UV-Vis spectroscopy, photoelectric conversion
