Abstract
The invention features organic photoreceptors that include a charge transport compound having the formula: ##STR1## PA1 where X is an N-alkyl-substituted carbazole, an N-aryl-substituted carbazole, or a p-(N,N-disubstituted)arylamine; PA1 Ar is a group having the formula: ##STR2## PA1 R.sup.1 is a hydrogen, halogen, or alkyl group; R is a hydrogen, halogen, OH, CN, OR.sup.2, or OCOR.sup.3 group; R.sup.2 is an alkyl, aryl, or alkaryl group; R.sup.3 is a hydrogen, alkyl, aryl, or haloalkyl group; n is 0 or 1; A is a group having the formula: ##STR3## PA1 Z is O or S; Q is O, S, or CH.sub.2 ; and m is 0 or 1.
