Oxadiazole Derivative, and Light-Emitting Element and Light-Emitting Device Using Oxadiazole Derivative |
摘要 |
An object is to provide a novel oxadiazole derivative that has high excitation energy, particularly high triplet excitation energy, or to provide a new oxadiazole derivative that is a bipolar substance. An oxadiazole derivative represented by General Formula (G1) is provided. In the formula, R1 and R2 independently represent a hydrogen atom, an alkyl group having 1 to 4 carbon atoms, or a substituted or unsubstituted aryl group having 6 to 10 carbon atoms. At least one of R1 and R2 represents a substituted or unsubstituted aryl group having 6 to 10 carbon atoms in a ring. Ar1 represents a substituted or unsubstituted aryl group having 6 to 10 carbon atoms in a ring.
