专利汇可以提供Organic photoconductive composition and electrophotographic member专利检索,专利查询,专利分析的服务。并且There are disclosed photoconductive insulating compositions and electrophotographic members utilizing such composition which are transfer complexes of a Lewis acid, preferably 2, 4, 7-trinitro9-fluorenone or 2, 4, 5, 7-tetranitro-9-fluoroenone combined with a dicarbazolyl compound characterized by the formula: WHEREIN R is a member selected from the group consisting of aryls, alkyls, and cycloalkyls, preferably discarbazolyl cyclobutane, and combined with a vinyl heterocyclic aromatic polymer or a vinyl polynuclear aromatic polymer which is believed to act both as a binder and a photoconductor in the combination. The preferred polymer is either a poly-N-vinyl carbazole or a halogenated poly-N-vinyl carbazole having a molecular weight high enough to impart high viscosity to the composition. The mole ratio of discarbazolyl compound to Lewis acid is from 1:0.5 to 1: 5 and preferably from 1:2 to 1:5. At mole ratios above 1:2 increased electrophotographic speed is attained.,下面是Organic photoconductive composition and electrophotographic member专利的具体信息内容。
