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.
Some embodiments described herein relate to ionic liquids comprising an anion of a heteraromatic compound such as optionally substituted pyrrolide, optionally substituted pyrazolide, optionally substituted indolide, optionally substituted phospholide, or optionally substituted imidazolide. Methods and devices for gas separation or gas absorption related to these ionic liquids are also described herein.
