Anthracene derivative, light-emitting element, light-emitting device, and electronic appliance

摘要

Novel anthracene derivatives are provided. Further, a light-emitting element, a light-emitting device, and an electronic appliance each using the novel anthracene derivative are provided. Anthracene derivatives represented by general formulae (G11) and (G21) are provided. The anthracene derivatives represented by the general formulae (G11) and (G21) each emit blue light with high color purity and have a carrier-transporting property. Therefore, each of the anthracene derivatives represented by the general formulae (G11) and (G21) is suitable for use in a light-emitting element, a light-emitting device, and an electronic appliance.;

1. An anthracene derivative represented by a formula (G21), wherein: Ar1, Ar2, Ar4, and Ar5 independently represent a substituted or unsubstituted aryl group having 6 to 13 carbon atoms; Ar3 represents a substituted arylene group having 6 to 13 carbon atoms; and Ar4 and one of Ar3 and Ar5 are bonded to each other to forms a five-membered ring.
