摘要 |
A novel compound having high triplet excitation energy and a bipolar property is provided. Specifically, a phenanthrene compound represented by General Formula (G1) is provided where R11 to R19 and R21 to R27 separately represent any one of hydrogen, an alkyl group having 1 to 4 carbon atoms, and a substituted or unsubstituted aryl group having 6 to 13 carbon atoms, Ar represents a substituted or unsubstituted arylene group having 6 to 13 carbon atoms, and Z represents a sulfur atom or an oxygen atom. The use of the phenanthrene compound as a host material of a light-emitting layer in the presence of a phosphorescent dopant allows the formation of a light-emitting element with high current efficiency. |
