Title:
AROMATIC AMINE DERIVATIVE AND ORGANIC ELECTROLUMINESCENT DEVICE USING SAME
Document Type and Number:
WIPO Patent Application WO/2007/100096
Kind Code:
A1
Abstract:
Disclosed is an aromatic amine derivative represented by the general formula (I) below. Also disclosed is an organic electroluminescent device wherein an organic thin film composed of one or more layers including at least a light-emitting layer is interposed between a cathode and an anode. Since at least one layer of the organic thin film contains the aromatic amine derivative by itself or as a component of a mixture, the organic electroluminescent device is able to obtain blue light emission with high color purity, while having long life and high luminous efficiency. Namely, the aromatic amine derivative enables to realize such an organic electroluminescent device. [In the formula, R1-R10 independently represent a hydrogen atom, an alkyl group, an aryl group, an aralkyl group, a cycloalkyl group, an alkoxyl group, an aryloxy group, an arylamino group, an alkylamino group, a silyl group, or a heterocyclic group; and Ar1-Ar4 independently represent an alkyl group, an aryl group, an aralkyl group, a cycloalkyl group or a heterocyclic group.]
