Abstract

The relative widths of Iπ bands in poly-(p-phenylene) , polyphenylene sulfide and polyphenylene oxide are deduced from electron energy loss experiments. From measurements of the chemical shift of the carbon K absorption edge, the charge on carbon atoms in different coordination is estimated. In AsF₅doped poly-(p-phenylene) two states inside the gap have been seen, consistent with a bipolaron model for the conductivity.
