Fabrication, Structure and Conductivity of Hybrid Organic/Inorganic Langmuir-Blodgett Films of Polyquinoline/Octadecylamine/Rare Earth-substituted Heteropolyanion

Abstract

Abstract: Three kinds of hybrid organic/inorganic Langmuir-Blodgett films are obtained by the compact organization of poly(1,2 dihydro-2,2,4-trimethyl)quinoline(abridged as PQ), octadecylamine(abridged as OA) and rare earth substituted heteropolyanions[abridged as RE(PW₁₁ )₂, RE=Ce^Ⅲ, Eu^Ⅲ, Gd ^Ⅲ] using the Langmuir-Blodgett technique. They are characterized by the π-A isotherms, the absorption spectra, the fluorescence spectra and the atomic force microscope. The scanning tunneling microscopy shows that the conductivity of the hybrid LB films is much better after heteropolyanions having been incorporated in the films.

Key words: Polyquinoline, Heteropolyanion, LB film, Morphology, Conductivity
