Abstract

Layered Bronsted acids, $HMMoO_6$·$H_2O$ (M=Nb, Ta) possessing a rutile-related structure, readily intercalates aniline giving $(C_6H_5NH_3)_xH_{1−x}MMoO_6·H_2O (x˜0.35)$. Oxidation of the latter in air at 130°C polymerizes the interlayer aniline to give $(PANI)_xH_{1−x}MMoO_6$ nanocomposites (PANI=polyaniline). Characterization of the composites by various physical methods reveals that the polymerization is near-quantitative, occurring within the galleries of the inorganic host. EPR spectroscopy shows a single resonance at g=2.003 which is characteristic of PANI, indicating that the inorganic host does not participate in the oxidative polymerization of aniline.
