摘要

Poly(phenylene vinylene) (PPV) film was synthesized via a soluble precursor poly-mer. Strong fluorescence at 500-600nm was observed in both precursor and PPV film.Room-temperature conductivity of PPV film doped with FeCl3 depends on the eliminationtemperature

the concentration of FeCl3 and doping time. The maximum conductivity ofdoped PPV at room-temperature can reach about 40 S·cm-1. The temperature depen-dence of conductivity was controlled by 1D-VRH (1 Dimension Variable Range Hopping)model with To value of 3.9×103K.Non-Ohmic conductivity resulting from Schottky effect was observed and the value of converted voltage from Ohmic region into non-Ohmic region at the current-voltage characteristic was found to be dependent upon the work function of electrodes.
