A novel amine derivative is represented by the following Formula 1:
An organic electroluminescent (EL) device includes: an anode, a cathode, an emission layer between the anode and the cathode, and a plurality of layers between the anode and the emission layer, wherein a material for an organic EL device including the amine derivative is in at least one layer selected from the plurality of layers between the anode and the emission layer. In a blue to bluish green region of an organic EL device, the driving voltage of the organic EL device may be decreased, and the emission efficiency thereof may be significantly improved.
一种新型胺衍生物由以下化学式1表示:一种有机电致发光(EL)器件包括:阳极、阴极、位于阳极和阴极之间的发射层,以及位于阳极和发射层之间的多层,其中包括该胺衍生物的有机EL器件材料至少在所选多层之一中。在有机EL器件的蓝色至蓝绿色区域,有机EL器件的驱动电压可能降低,其发射效率可能显著提高。
