摘要：

Films of poly(p-phenylene vinylene) (PPV) were synthesized via pyrolysis of a water-soluble sulphonium polyelectrolyte, derived from p-xylylene bis(tetrahydrothiophenium chloride). The thermal elimination reaction of the sulfide group was studied by differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA). The structure of the completely converted, unoriented PPV films was characterized using IR spectroscopy and X-ray diffraction. Doping of PPV films with FeCl3 in nitromethane was studied. Films of different dopant concentrations y = (FeCl(x)/C8H6) were obtained by varying the molarity of the doping solutions and by changing the immersion time. The electrical conductivity of FeCl3-doped PPV films was measured as a function of concentration and doping time. The d.c. conductivity reached a maximum value of sigma(dc) = 35 ohm-1 cm-1.
