| 摘要 |
A host compound for a light emitting layer, which is excellent in electron transporting capability and hole blocking capability, has a high triplet excitation level and is capable of completely confining triplet excitons of a phosphorescent material, is provided as a material for an organic electroluminescent device having a high efficiency, and an organic electroluminescent device having a high efficiency and a high luminance is provided by using this compound. The compound having a triazole ring structure to which a pyridyl group substituted with a carbazolyl group is bonded, is represented by the following general formula (1), and the organic electroluminescent device containing a pair of electrodes and at least one organic layer sandwitched therebetween is characterized in that the compound, which is represented by the following general formula (1) and has a triazole ring structure to which a pyridyl group substituted with a carbazolyl group is bonded, is used as a constitutional material of at least one organic layer in the organic electroluminescent device.
