The present invention is directed to a carbazole containing compound and an organic electroluminescent display device using the same. In particular, the carbazole containing compound may be a blue phosphorescent host material having a large triplet energy gap compared to 4,4′-N,N′-dicarbazole-biphenyl (CBP) and effectively transfers energy to a blue dopant. An organic layer formed using the carbazole containing compound may be used in an organic electroluminescent display device in order to provide high efficiency, improved color purity, and improved power consumption characteristics.
本发明涉及一种含有
咔唑基的化合物以及使用该化合物的有机电致发光显示装置。具体来说,该含有
咔唑基的化合物可能是一种蓝色
磷光主体材料,其与4,4′-N,N′-二
咔唑基
联苯(CBP)相比具有较大的三重态能隙,并有效地将能量转移给蓝色掺杂剂。使用该含有
咔唑基的有机层可用于有机电致发光显示装置,以提供高效率、改善色彩纯度和改善功耗特性。
