| Abstract: | Aromatic polyimide based materials have being investigated widely because of their versatile properties including their photoconductivities. It is proved that the photoconductivities of the polyimides origin from the charge transfer complexes(CTCs) formed among the adjacent polyimide molecules in polymer bulk. When electron donors are doped into the polymer matrices or incorporated into the main chains of polyimides, the photoconductivty of aromatic polyimides improves greatly. At the same time, the CTCs formed and the charge carriers transfer easily in the polyimides with ordered aggregatn structure, and in result excellent photoconductive properties result. The infuences of molecular chain structure, charge transfer complexes, chain orientaton, and doping on the photoconductive properties of the polyimides were describd extensively. |
