title: Preparation and photocatalytic activity of an electrostatically self-assembled film made of [PMo12O40](3-) and a bipolar hemicyanine cation.
abstract: 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 charge transfer between two film-forming components might occur in the film. The photocatalytic performance of the film was studied for the degradation of aqueous dye Methyl Red (MR) under UV irradiation. The degradation of MR follows Langmuir-Hinshelwood first-order kinetics.
