摘要
The present invention relates to a highly efficient carbazole-based compound and to an organic electroluminescence device including the same. According to the present invention, provided are a compound for an organic electroluminescence device and an organic electroluminescence device including the compound, in which a carbazole-based phosphine oxide compound, which is a compound intended for an organic electroluminescence device, is employed to overcome the problems of conventional compounds for organic electroluminescence devices, i.e. those of instable thermal stability and low efficiency, and particularly, the compound of the present invention exhibits superior efficiency in pure-blue phosphorescent devices.
