Abstract
Abstract Poly(phenyl-1,4-phenylene vinylene) (PhPPV) and a series of arylene vinylene copolymers containing phenyl-monosubstituted arylene units and either unsubstituted or 2,5-dialkoxy 1,4-phenylene vinylene units was prepared from water-soluble, sulfonium salt precursor polymers. The conversions of the respective precursor polymers to the conjugated polymers were studied by thermogravimetric analysis, and the arylene vinylene polymers so formed were characterized by elemental analysis and by FT-IR and UV-Vis spectroscopy. The substituted polymers could be drawn above their softening points even though some degree of crosslinking occurred during the thermal elimination step. Doping of the polymer films with either iodine or antimony pentafluoride vapor led to conductivities in the 10−4 S.cm−1 range. The low level of conductivity observed may be a result of morphological perturbations that inhibit the interchain hopping of the charge carriers.
