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 has high electron transport efficiency, which can prevent crystallization during the formation of the device; is effective in forming a layer(s) to improve the current property of the device, and thus reduces the driving voltage of the device; and has the advantages of providing an OLED device having advanced power efficiency. 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 have to comprise a hole blocking layer, and thus can decrease the voltage needs of the device.
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具有高电子传输效率,可以防止在器件形成过程中发生结晶;在形成一层或多层以改善器件的电流特性方面有效,并因此降低器件的驱动电压;并具有提供具有先进功率效率的OLED器件的优点。虽然包括传统有机电致发光化合物的有机电致发光器件需要孔阻挡层,但包括本发明的有机电致发光化合物的有机电致发光器件不需要包括孔阻挡层,因此可以降低器件的电压需求。
