Influence of ionic forms of polymethine dyes on the photoconductivity of doped films of poly-N-epoxypropylcarbazole

Thr features of photoconductivity of the films of poly-N-epoxypropylcarbazo le doped with cationic. squarylium and merocyanine dyes are investigated. U nder temperature growth starting from room the photoconductivity of the fil ms with cationic anti squarylium dyes increases more strongly as compared t o the similar films with merocyanine. It was explained by a destruction of structural traps close to electrically charged fragments of dyes. In contra st to the films of the first two types, the photoconductivity of the films with merocyanine dye depends sublinearly on incident light intensity due to an effective bimolecular charges recombination.
