ABSTRACT:
Arylamine derivatives that can be utilized as hole transport or hole injection materials of organic electroluminescence devices, electrophotographic reactors, etc., and synthetic intermediates thereof, and processes of producing those. The arylamine derivative is represented by the general formula (1):wherein R1to R4each independently represents a hydrogen atom, an alkyl group, an alkoxy group, an aryl group, an aryloxy group, a halogen atom, an amino group, etc.; Ar1and Ar2each independently represents a substituted or unsubstituted aryl group or hetero-aromatic group, and Ar1and Ar2may form a nitrogen-containing heterocyclic ring together with the nitrogen atom to which Ar1and Ar2bond; and Ar3represents a substituted or unsubstituted arylene group.
