Photoconductive, photovoltaic and information properties of new carbazole-based oligomeric film compositions doped with 2,2-diphenyl-1-picrylhydrazyl

The novel photosemiconducting magneto-sensitive thin film structures based on carbazole-containing oligomer doped by stable organic radical 2,2-diphenyl-1-picrylhydrazyl as the photoconductivity sensitizer have been prepared. Their spectral, photoconductive, photovoltaic and information properties were investigated. It was shown, that the investigated composites exhibit photoconductivity and photovoltaic properties under illumination by light from the respective stable radical absorption region. The features of the photoconductive and photovoltaic properties of the investigated composites, as well as the possible mechanisms of the photovoltaic effect and charge carriers photogeneration were discussed. It was shown that the prepared films can be used as reversible holographic recording media.
