dc.description.abstractThe changes in the conductivity of chlorine-doped poly(seleno-p-arylen diamine)s have been studied with temperature, storage time and ambient atmosphere, The samples have also been studied using X-ray photoelectron spectroscopy (XPS) and electron spin resonance (ESR). The conductivity of the polymers with carbonyl in their backbone decreases with storage time but is insensitive to oxygen, The decrease in conductivity with time is attributed to the breaking of the Se-N bonds by chlorine attack, which induces polymer degradation as shown by XPS. The conductivity of the polymers without carbonyl in their backbone was increased by oxygen. This increase can be attributed to oxidation of these polymers and to bipolaron formation as shown by ESR measurements. (C) 1996 Elsevier Science Limited
