|Abstract:||X-Ray photoelectron spectroscopy (XPS) studies have been performed on conductive polypyrrole (PPY)-halogen complexes, such as PPY-I//2, PPY-Br//2, and PPY-Cl//2 complexes, prepared by the simultaneous chemical polymerization and oxidation of pyrrole by the respective halogens. Substantial halogenation of the pyrrole ring was observed in the case of PPY-Cl//2 and PPY-Br//2 complexes. In the case of PPY-Br//2 complex, the ratio of covalent to ionic bromide content can be effectively varied over a wide range by varying the bromine to monomer ratio used for polymerization. The increase in covalent bromide content causes a decrease in the electrical conductivity of the complex.|
