Abstract

Mössbauer, far-infrared, and X-ray photoemission spectroscopy (XPS) studies have been made on doped (SnCl₂ or SnCl₄) polyethynylfluorenol (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.
