摘要:
Novel anthracene derivatives, novel materials capable of blue light emission with high color purity, and a light-emitting element, a light-emitting device, and an electronic device using any of the novel materials. The anthracene derivative represented by general formula (1) is provided. With the anthracene derivative, a light-emitting element with high emission efficiency can be provided. With the anthracene derivative, a light-emitting element emitting blue light with high color purity can be provided. In the formula, A1 represents a substituted or unsubstituted phenyl group, B1 represents any of an alkyl group having 1 to 4 carbon atoms or a substituted or unsubstituted phenyl group, α represents any of a substituted or unsubstituted phenylene group or a substituted or unsubstituted biphenyl-4,4′-diyl group, and R1 to R9 individually represent any of hydrogen, an alkyl group having 1 to 4 carbon atoms, or a substituted or unsubstituted phenyl group.
