CARBAZOLE DERIVATIVE, LIGHT EMITTING ELEMENT, AND LIGHT EMITTING APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a substance of large excitation energy, particularly a compound having an energy gap broader than the triplet excitation energy of a phosphorescent compound emitting visible light.SOLUTION: There is provided a carbazole derivative represented by general formula (G1), comprising a heteroaromatic ring containing, in its molecule, an oxadiazole skeleton or a quinoxaline skeleton each being a heteroaromatic ring having an electron transporting property, and a carbazole skeleton having a hole transporting property [Q is a specific substituent having an oxadiazole skeleton or a quinoxaline skeleton].SELECTED DRAWING: None
