The present invention relates to a cyclic tertiary amine compound of formula 1 and an organic light emitting device.n n n Formula 1n n n n n n n n In Formula 1 above,n n n A is 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 all four A's may be the same or different. There is,n n n Y 1 is a substituted or unsubstituted arylene group or a substituted or unsubstituted heterocyclic divalent group,n n n Y 2 is a group of formula (2), a substituted or unsubstituted condensed ring arylene group, or a substituted or unsubstituted heterocyclic divalent group.n n n Formula 2n n n n n n n n In Formula 2 above,n n n R 1 to R 8 are independently a hydrogen atom, a halogen atom, an alkyl or alkoxy group having 1 to 6 carbon atoms, an aryl group or a heterocyclic group,n n n Z is a single bond, arylene group, -CH 2- , -CH = CH-, -C≡C-, -C (CH 3 ) 2- , -CO-, -O-, -S- or -SO 2 -to be.n n n By using the cyclic tertiary amine compound as a hole transport material, a hole injection material or an organic electroluminescent material, an organic electroluminescent (EL) device having a high luminous efficiency and a long lifetime can be obtained.n n n Cyclic tertiary amine compound, organic EL device, high luminous efficiency, extended lifetime, high performance display |
