The present invention relates to a novel organic electroluminescent compound and an organic electroluminescent device comprising the same. The organic electroluminescent compound according to the present invention improves the current property of the device thereby reducing the driving voltage of the device. While organic electroluminescent devices comprising conventional organic electroluminescent compounds need hole blocking layers, the organic electroluminescent device comprising the organic electroluminescent compound of the present invention does not need to comprise a hole blocking layer and has an improved lifespan.
本发明涉及一种新型有机电致发光化合物和包括该化合物的有机电致发光器件。根据本发明的有机电致发光化合物改善了器件的电流特性,从而降低了器件的驱动电压。传统有机电致发光化合物构成的有机电致发光器件需要孔阻挡层,而本发明的有机电致发光化合物构成的有机电致发光器件不需要包括孔阻挡层,并且寿命得到了改善。
