Patent ID: 8481177

Claim:
An organic electroluminescence device, comprising an organic thin film layer between an anode and a cathode, wherein: the organic thin film layer comprises a multilayer stack in which a hole-injecting layer, a hole-transporting layer, an emitting layer and an electron-transporting layer are stacked sequentially from the anode; the hole-injecting layer comprises a material for an organic electroluminescence device comprising an indenofluorenedione derivative represented by any of formulae (IIa), (IIb), (IIc) and (III): R 11 to R 50 represent, independently of one another, a hydrogen atom, an alkyl group optionally substituted by a substituent, an aryl group optionally substituted by a substituent, an alkoxy group optionally substituted by a substituent, an aryloxy group optionally substituted by a substituent, a fluoroalkyl group optionally substituted by a substituent, or a heterocycle optionally substituted by a substituent, with proviso that all of R 11 to R 50 may not be a hydrogen atom; and R 11 to R 50 are optionally bonded to each other to form a ring.
