Cyclic tertiary amine compound and organic electroluminescent device containing the compound

Abstract

The present invention relates to a cyclic tertiary amine compound represented by a formula (1) and an organic luminescent device. 1 wherein A represents an alkyl group having 1 to 6 carbon atoms, a substituted or unsubstituted aryl group, a substituted or unsubstituted aralkyl group, or a substituted or unsubstituted heterocyclic group, and four As may be all the same or partly different; y1 represents a substituted or unsubstituted arylene group, or a substituted or unsubstituted heterocyclic divalent group; y2 represents a group represented by a formula (2), a substituted or unsubstituted condensed ring arylene group, or a substituted or unsubstituted heterocyclic divalent group, 2 wherein R1 to R8 in the formula (2) independently represents a hydrogen atom, a halogen atom, an alkyl or alkoxy group having 1 to 6 carbon atoms, an aryl group or a heterocyclic group; and Z represents single bond, an arylene group, —CH2—, —CH═CH—, —C≡C—, —C(CH3)2—, —CO—, —O—, —S— or —SO2—. Use of the cyclic tertiary amine compound as a hole transport material, a hole injection material or an organic electroluminescent material can provide organic EL devices having high luminous efficiency and a long service life.
