The present invention provides a carbazole-containing compound and an organic electroluminescent device using the same. Such a carbazole-containing compound has a large triplet energy gap and is effective in energy transfer to a blue dopant as compared to CBP (4,4'-N, N'-dicarbazole-biphenyl) as a blue phosphorescent host material. When employing an organic film formed using such a carbazole-containing compound, it is possible to manufacture an organic EL device having high efficiency and improved color purity and power consumption characteristics. |
