Abstract
Ambipolar photoconductive composition comprising the product of the in situ polymerization of at least one cyclic compound of the formula: ##EQU1## wherein Ar is a polyaromatic nucleus selected from the group consisting of diradicals of naphthalene, anthracene, pyrene and carbazole; PA1 X and Y are independently selected from the group consisting of halogen, NO.sub.2, NH.sub.2 ; lower alkyl, phenyl, phenoxy, lower alkoxy, carboxy, hydroxyl, lower alkyl esters and aryl esters; PA1 m and n can range from 0 to the total number of replaceable hydrogens on the polyaromatic nucleus; In a polymeric host resin. By the appropriate in situ polymerization of the above compound in the host polymer, it is possible to produce an interpretating photoconductive netword throughout the host polymer. The resulting photoconductive materials can be incorporated into an imaging member in an electrostatographic imaging system and function in either a positive or negative charging mode.
