Abstract
Mossbauer, far-infrared, and X-ray photoemission spectroscopy (XPS) studies have been made on doped (SnCl2 or SnCl2) polyethynylfluorenol (PEFI) 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 (SnCl4.2H(2)O) species in the SnCl4 doping, With SnCl4 doping, the nature of the species is less certain, although both Sn(II) and hexacoordinated Sn(IV) appear to be present.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
