Title:
AROMATIC AMINE DERIVATIVE AND ORGANIC ELECTROLUMINESCENT DEVICE USING THE SAME
Document Type and Number:
WIPO Patent Application WO/2008/032631
Kind Code:
A1
Abstract:
Disclosed is a novel aromatic amine derivative having specific structure. 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, and at least one layer of the organic thin film, especially a hole transport layer contains the aromatic amine derivative by itself or as a component of a mixture. By having such a constitution, the organic electroluminescent device is improved in production yield and has long life, while being reduced in driving voltage and suppressed in crystallization of molecules. Namely, the aromatic amine derivative enables to realize such an organic electroluminescent device.
