Abstract:
Provided is a bipolar substance having high excitation energy, in particular, high triplet-excitation energy. An oxadiazole derivative represented by General Formula (G1) below is provided In the formula, Ar represents a substituted or unsubstituted aryl group having 6 to 10 carbon atoms in a ring. R1 represents an alkyl group having 1 to 4 carbon atoms or a substituted or unsubstituted aryl group having 6 to 10 carbon atoms in a ring. R2 represents hydrogen, an alkyl group having 1 to 4 carbon atoms, or a substituted or unsubstituted aryl group having 6 to 10 carbon atoms in a ring.
