Communication: Polyaniline (PAN)-an electrically conductive conjugated polymer-was always of major interest due to its unique properties. However, the insolubility of PAN in common organic solvents hampered commercial exploitation. The synthesis of new copolymers of aniline and chalcophenes is reported. The Figure shows a scanning electron micrograph of a poly[4-(2-furyl)benzenamine] film cast from tetrahydrofuran.
