摘要

Four PPV polymers have been synthesized through Witting reaction, I = poly(p-phenylene vinylene), II = poly(p-phenylene vinylene-co-w-phenylene vinylene), III = poly(p-phenylene vinylene-co-o-phenylene vinylene) and IV = poly(p-phenylene-l ,5-hexadiene). Electrical conductivity measurements show that the conductivity of polymer HI is higher than that of polymers I and II. The dihedral angle measurements indicates that the irregularity of polymer chains is the main reason for this fact. The interruption of chain conjugation by aliphatic segments (polymer IV) will increase the conductivity by increasing the chain mobility. The electrical conductivity of the polymers is increased by doping with iodine and by raising the temperature. The effect of annealing with different temperatures on conductivity was studied; the results show that structural conformation of polymeric chain is the main factor affecting electrical conductivity.
