Title:
芳香族アミン誘導体及びそれらを用いた有機エレクトロルミネッセンス素子
Document Type and Number:
Japanese Patent JP5258562
Kind Code:
B2
Abstract:
A novel aromatic amine derivative which is a diamine compound having a p-terphenyl-4,4"-diyl structure. An organic electroluminescence device which is composed of one or more organic thin film layers including at least one light emitting layer sandwiched between a cathode and an anode. Since at least one of the organic thin film layers contains the aromatic amine derivative singly or combination of two or more, the tendency of molecular crystallization is reduced and the yield in the fabrication of electroluminescence devices is enhanced. The aromatic amine derivative enables the production of electroluminescence devices having a prolonged lifetime and a high efficiency even after storing at high temperatures.
