Sensitization in the Photoconductance of Polyacenaphthylene

Abstract

Abstract The sensitization of the photoconductivity in polyacenaphthylene by a dye and/or a Lewis acid was investigated. The most effective materials are methylene blue (E1⁄2=1500 lux. sec.), rhoda-mine 6G (6000 lux. sec.), and victoria pure blue (6500 lux. sec.) in the dye sensitization, and 1-nitroanthraquinone (1200 lux. sec.), 2, 3-dichloronaphthoquinone (1400 lux. sec.), 1, 5-dichlo-roanthraquinone (1500 lux. sec.), chloranil (1800 lux. sec.), and 2-chloroanthraquinone (1900 lux. sec.) in the Lewis-acid sensitization. The combined effects of a dye and a strong acid were determined in the case of polyacenaphthylene as well as poly-N-vinylcarbazole.
