An electrostatically self-assembled film of PMo12/H6 has successfully been prepared on quartz substrates by alternating adsorption of [PMo12O40(3-) (PMo12) and a bipolar hemicyanine derivative of (E)-1,1'-(hexane-1,6-diyl)bis(4-(4-(dimethylamino)styryl)pyridinium) bromide (H6Br2). The UV-visible spectra showed that the film was uniformly deposited and the
