摘要：Four conjugated poly-Schiff bases with the same backbone but different side groups were prepared by polycondensation of 1,4-diaminobenzene with glyoxal, 2,3-butanedione, 3,4-hexanedione and 4,5-octanedione, respectively. The polymers were characterized by FT-IR, elemental analysis, etc. It was discovered that the conjugated poly-Schiff bases with alkyl side groups can be dissolved in common organic solvents. Electrical conductivities of the pristine polymers and their relationship with temperature were measured, showing that the polymers are typical semiconductors. When the polymers were doped with iodine, electrical conductivity increased by seven to nine orders of magnitude (up to 10(-3)-10(-4) S/cm). The effect of side groups on the conductivity of the I2-doped polymers is discussed.
