Abstract :
The photoconductivity and photodielectrical properties of films of an aromatic polyimide with the addition of cationic and anionic polymethyne dyestuffs have been studied. The sensitization of the photoeffect of the dyes with different ionicity in polyimide films with donor and acceptor units develops the possibility of photogeneration of holes and electrons from dyestuff molecules and internal bipolar conductivity of the polyimide.
