| 摘要 |
The present invention relates to a cyclic tertiary amine compound represented by a formula (1) and an organic luminescent device. 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, 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.
