Solid-state H-2 NMR determination of poly(aniline) conformation within a MoO3 nanocomposite

The conformation of poly(aniline) (PANI) within a MoO3, nanocomposite is investigated by solid-state H-2 MMR (see also cover). This technique is demonstrated to be highly suited to providing information about the structure of polymers intercalated within transition metal oxide hosts that cannot be obtained by other methods. Through a series of 1D and 2D experiments it is shown that PANI is organized within the interlayer regions of the inorganic host and that order within the composite is not determined solely by the oxide layers.
