Polymerization of aniline in the galleries of layered HNbMoO6

Insertion of aniline molecules and subsequent polymerization using FeCl3, a s an oxidizing agent were examined in the layers of rutile-type HNbMoO6. Al though the polyaniline/host ratio was variable depending on the amount of i ntercalated aniline before polymerization, the interlayer spacing was const ant as similar to 6.3 Angstrom regardless of the ratios. Comparison of FT-I R and FT-Raman spectra for (PANI)(y)NbMoO6 (0.26 less than or equal to y le ss than or equal to 0.64) clearly showed that both quinoid and benzenoid fo rms exist in the galleries of inorganic host. IR and Raman active modes of extracted PANI from the matrix were quite similar to those of emeraldine sa lt. (C) 1999 Elsevier Science BN. All rights reserved.
