Abstract
A polymeric analogue of crystal violet in which the triarylmethane moiety is pendent from a polyester backbone has been examined as a sensitizer for photoconductivity in poly-N-vinyicarbazole. In both positive and negative surface charging modes, the dark decay rates increase linearly with sensitizer concentration, but are lower than those for monomeric crystal violet sensitization. The photodecay rates, in both modes, show optimal concentration dependence and are higher than those for monomeric crystal violet.
