Abstract
Organic electron donor compounds for use in electrophotographic constructions must ordinarily be sensitized to desired regions of the electromagnetic spectrum. Highly fluorinated aliphatic sulfonyl, carbonyl, or carbonyloxy dyes have been found to be efficient sensitizers for such organic donor compounds.
Claims15
A spectrally sensitized organic charge transport material comprising an electronically active organic donor compound sensitized with a dye of the formula ##STR14## Wherein R.sub.a represents a monovalent chromophoric radical, M represents ##STR15## R.sub.f represents a highly fluorinated aliphatic radical and R represents a monovalent electron-withdrawing radical.
A spectrally sensitized organic charge transport material comprising an electronically active organic donor compound having the formula ##STR16## wherein R.sup.1 and Y are independently selected from the group consisting of aliphatic, aromatic, heterocyclic, and mixed aliphatic-aromatic groups and a sensitizing amount of a disulfone dye having the formula:
- ##STR17## wherein R.sub.a represents a monovalent chromophoric radical, M represents ##STR18## R.sub.f represents a highly fluorinated aliphatic radical, and R represents a monovalent electron-withdrawing radical.
