Photoconductive Polymer: Its Preparation and Photoconductive Behavior

Abstract

Abstract A photoconductive polymer, poly[1, 3-diphenyl-5-(4-vinylphenyl)-2-pyrazoline], has been synthesized from polystyrene via polyvinyl-acetophenone and polyvinylbenzalacetophenone. Under carefully controlled preparative conditions, a high degree of substitution has been obtained without its being insoluble. The photoconductive behavior of the polymer has been measured using a sandwich-type cell. The current obeyed Ohm’s law, and the value of Ip/Id was 34 or 147 depending on whether the illuminated electrode was positive or negative respectively.
