To determine specifics of aromatic polyimides as a new class of polymeric photoconductors, spectroscopic and photoelectric properties of two soluble aromatic polyimides were examined. These polyimides differ in the bridge group in the diimide fragments. The photoconductivity of polyimide films and its spectroscopic distribution, kinetic features of increase and decay of photocurrent were examined with continuous and impulse (third harmonic of a neodymium laser) light, according to light intensity, electric field strength and temperature. Possible mechanisms of forming and transferring charge carriers in polyimides were investigated.
