ABSTRACT:
New compounds of the formula ##STR1## wherein n is 1 or 2; R.sup.1 and R.sup.2 are alkyl or aralkyl; R.sup.3 is alkyl; when n is 1, R.sup.4 is alkyl, aralkyl, alkenyl, aralkenyl, aryl or a polyether radical having up to 10 ether groups; and when n is 2, R.sup.4 is alkylene, aralkylene, alkenylene, aralkenylene, arylene or a divalent polyether radical having up to 10 ether groups. The compounds are highly efficacious organic photoconductors for use in electrophotography, exhibiting improved pre-exposure fatigue resistance and blooming properties as compared with known photoconductors. Photoconductive elements containing these compounds are also described.
