Characterizations of interlayer organic-inorganic nanohybrid of molybdenum trioxide with polyaniline and poly(o-anisidine)

Characterizations of layered MoO₃ host with interlayer polyaniline (PANI) and poly(o-anisidine) (PoANIS), i.e. (PANI)_xMoO₃ and (PoANIS)_xMoO₃, respectively, have been carried out by means of X-ray diffraction (XRD), infrared (IR) spectra, thermogravimetry (TG), and solid-state nuclear magnetic resonance (NMR) analyses. The guest organic components, i.e. PANI and PoANIS, are accommodated into MoO₃ interlayers by ion-exchange process. From these detailed characterization studies, it is found that the interlayer PANI and PoANIS chains have neutralized units as well as cationic units. Moreover, the (PANI)_xMoO₃ and (PoANIS)_xMoO₃ hybrids have enough interlayer spaces due to almost perpendicular orientation of benzene ring into PANI and PoANIS chains to the MoO₃ layer.
