Abstract
Photoconductive composition comprising an insulating polymeric matrix and a compound of the formula ##STR1## WHEREIN Ar is anthryl; naphthyl; pyrenyl; indolyl; N-alkyl 2-CARBAZYL; JULOLIDINYL; AND THE SUBSTITUTED ANALOGUES THEREOF, WHEREIN SAID SUBSTITUENTS ARE CAPABLE OF RELEASING ELECTRONS TO THE RELATIVELY ELECTRON DEFICIENT CENTERS WITHIN THE COMPOUND; X is --NO.sub.2 or halogen; and N can range from 1 to 5. These compositions have good spectral response in the visible region of the electromagnetic spectrum and are suitable for use in electrostatographic imaging members and methods.
Claims9
A photoconductive composition comprising a solid solution of at least one photogenerator compound represented by the formula ##STR3## wherein Ar is indolyl, N-alkyl 2-carbazyl, julolidinyl and the substituted analogues thereof, wherein said substituents are capable of releasing electrons to the relatively electron deficient centers within the compound;
- X is --NO.sub.2 or halogen;
- and
- n is from 1 to 5
- and an insulating polymeric matrix, said polymeric matrix being capable of rapid and efficient transport of charge carriers of at least one polarity.
A composition comprising from about 0.1 to about 99.9 weight percent of at least one photogenerator compound represented by the formula ##STR4## wherein Ar is indolyl, N-alkyl 2-carbazyl, julolidinyl and the substituted analogues thereof, wherein said substituents are capable of releasing electrons to the relatively electron deficient centers within the compound;
- X is --NO.sub.2 or halogen;
- and n is from 1 to 5
- in an insulating polymeric matrix, the minimum concentration of photogenerator compound relative to polymeric matrix being sufficient to render the composition photoconductive.
An electrophotographic imaging member comprising a conductive substrate and a photoconductive insulating layer operatively disposed in relation thereto, said photoconductive insulating layer comprising a composition containing from about 0.1 to about 99.9 weight percent of at least one photogenerator compound of the formula ##STR5## wherein Ar is indolyl, N-alkyl 2-carbazyl, julolidinyl and the substituted analogues thereof, wherein said substituents are capable of releasing electrons to the relatively electron deficient centers within the compound;
- X is --NO.sub.2 or halogen;
- and
- n is from 1 to 5
- in an insulating polymeric matrix, the minimum concentration of photogenerator compound relative to polymeric matrix being sufficient to render the composition photoconductive.
