SCHIFF BASE HAVING TRIPHENYLAMINE SKELETON AND PRODUCTION THEREOF

摘要

NEW MATERIAL:A Schiff base having a triphenylamine skeleton of formula I, wherein Ar is a group of formula II or III [wherein R1 is H, halogen, lower alkyl, lower alkoxy; R2, R3 are each (substd.) alkyl, (substd.) phenyl]. EXAMPLE:Compd. of formula IV. USE:It has all of the desired properties as basic electrophotographic characteristics such as chargeability, dark attenuation, light attenuation, etc. and is suitable for use as photoconductive material having excellent flexibility. PREPARATION:4-Aminotriphenylamine of formula V is condensed with an aldehyde of formula VI (wherein Ar is as defined above) to produce a compd. of formula I.
