Abstract

Mössbauer, far-infrared, and X-ray photoemission spectroscopy (XPS) studies have been made on doped (SnCl2 or SnCl4) (PEFl) and polyphenylacetylene (PPA). The nature of the tin as it is incorporated into the polymer is examined. The resistance values of the doped polymers are followed with relative humidity. Results point to tetrahedral (SnCl4 and octahedral (SnCl4 · 2H2O) species in the SnCl4 doping. With SnCl2 doping, the nature of the species is less certain, although both Sn(II) and hexacoordinated Sn(IV) appear to be present. Index Headings: Mössbauer
