Reaction of aniline with FeOCl. Formation and ordering of conducting polyaniline in a crystalline layered host

The intercalative polymerization reaction of aniline with FeOCl, an extensive physicochemical and spectroscopic characterization of the products, and their oxidative behaviour in air is reported. Conducting PANI (emeraldine salt) was found inside FeOCl by an in situ oxidative polymerization reaction. In the (PANI)(sub x)FeOCl, the reduced FeOCl framework dominates the electronic conduction. A detailed study of the reaction is discussed.
