Studies on the Preparation, Structure and Properties of LB films of 12-Tungstomolybdophosphheteropolyacid with Dimethyldioctadecylammonium

Abstract

Abstract: The LBfilms of two amphiphilic complexes, DODA/PW₉Mo₃O₄₀ and DODA/PW₆Mo₆O₄₀, were prepared from 12-tungstomolybdophosphheteropolyacid with dimethyldioctadecylammonium and their properties and the structure were characterized by UV-Vis absorption spectra, fluorescence spectra, low angle X-ray diffraction(LAXD) and π-A isotherms curves. The results showed that the molecular areas for each comlex are 0.56 nm², and all of them could form an idealized structure with a stability of the Langmuir-Blodgetl films.

Key words: 12-Tungstomolybdophosphheteropolyacid, Dimethyldioctadecylammonium, LB films, Low angle X-ray diffraction, Fluorescence emission spectrum
