An electrophotographic method has been used to study the photoconductivity in layers of new thermally stable soluble polyimides (PIs) distinguished by the structure of the donor benzimidazole and acceptor diimide fragments of the polymer chains and its sensitization by tetranitrofluorenone and by various classes of dyes. It is shown that the synthesized polymers possess intrinsic photosensitivity at a level of 3 * 10~3 - 10~3 - 10~4 cm~2/J in the spectral region up to 450 nm. The photosensitivity achieved for the sensitized PIs (3 * 10~5 - 2 * 10~4 cm~2/J in the spectral region 400 - 700 nm) shows that the synthesized PI materials are promising for creating recording media and liquid-crystal modulators.
