Abstract：The organic composite materials formed by Keggin lanthanide-substituted polyoxotungstate anion [Ln(SiW11O39)2]13- (in which Ln=La, Ce, Pr, Nd, Sm) and (E)-N-methyl-4-(2-(4′-dimethylaminophenyl)ethenyl)pyridinium cation with the stoichiometry of (C16H19N2)10K3[Ln(SiW11O39)2], have been synthesized and characterized by elemental analyses, thermogravimetric and differential thermal analyses, and IR, UV-Vis, and fluorescence spectroscopy. The results of spectra show that the title compounds have Keggin structure, and inorganic-organic composite materials are formed between the hemicyanine cations and the heteropoly anions, and the charge transfer occurs from the hemicyanine cations to the the heteropoly anions in title complexes. The compounds reported in this paper are interesting as optical materils.
