Patent ID: 8367222

Claim:
An organic electroluminescence device, comprising: (a) an anode; (b) a cathode; and (c) organic thin film layers provided between the anode and the cathode, wherein the organic thin film layers (c) comprise (c1) a light emitting layer, and (c2) a hole injecting layer and (c3) a hole transporting layer, or (c4) a hole injecting/transporting layer on a side which is closer to the anode (a) than the light emitting layer (c1) is, wherein the hole injecting layer (c2) or the hole injecting/transporting layer (c4) comprises an aromatic amine derivative (i) comprising a substituent of formula (1): wherein L 12 is a substituted or unsubstituted arylene group comprising 6 to 60 atoms forming a ring, a substituted or unsubstituted fluorenylene group, or a substituted or unsubstituted heteroarylene group comprising 5 to 60 atoms forming a ring, and R 5 is a hydrogen atom, a substituted or unsubstituted aryl group comprising 5 to 14 atoms forming a ring, a substituted or unsubstituted aryloxy group comprising 5 to 14 atoms forming a ring, a substituted or unsubstituted arylthio group comprising 5 to 14 atoms forming a ring, a branched or linear, substituted or unsubstituted alkyl group comprising 1 to 6 carbon atoms, or a branched or linear, substituted or unsubstituted alkoxycarbonyl group comprising 1 to 6 carbon atoms, a is 1, 2, or 3, and, when a is 2 or 3, multiple R 5 's are identical or different, and wherein the hole transporting layer (c3) or the hole injecting/transporting layer (c4) comprises an aromatic amine derivative (ii) comprising a substituent of formula (2): wherein X is NR 1 , L 1 is a substituted or unsubstituted arylene group comprising 6 to 60 atoms forming a ring, a substituted or unsubstituted fluorenylene group, or a substituted or unsubstituted heteroarylene group comprising 5 to 60 atoms forming a ring, R 1 is a substituted or unsubstituted aryl group comprising 5 to 14 atoms forming a ring, or a branched or linear, substituted or unsubstituted alkyl group comprising 1 to 6 carbon atoms, R 2 is a hydrogen atom, a substituted or unsubstituted aryl group comprising 5 to 14 atoms forming a ring, a substituted or unsubstituted aryloxy group comprising 5 to 14 atoms forming a ring, a substituted or unsubstituted arylthio group comprising 5 to 14 atoms forming a ring, a branched or linear, substituted or unsubstituted alkyl group comprising 1 to 6 carbon atoms, or a branched or linear, substituted or unsubstituted alkoxycarbonyl group comprising 1 to 6 carbon atoms, and n is an integer of 1 to 7, wherein the aromatic amine derivative (i) does not comprise the substituent of formula (2) in its structure, and wherein the aromatic amine derivative (ii) does not comprise the substituent of formula (1) in its structure.
