HETEROCYCLIC COMPOUND, LIGHT-EMITTING ELEMENT, LIGHT-EMITTING DEVICE, ELECTRONIC DEVICE AND LIGHTING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a novel heterocyclic compound, a novel heterocyclic compound that can be used in a light-emitting element, or a highly reliable light-emitting device, electronic device, and lighting device in each of which the light-emitting element using the novel heterocyclic compound is used.SOLUTION: One embodiment of the present invention is a heterocyclic compound represented by General Formula (G1). In General Formula (G1), each of Aand Aindependently represents nitrogen or carbon bonded to hydrogen, and at least one of Aand Arepresents nitrogen; Ar represents a substituted or unsubstituted arylene group having 6 to 18 carbon atoms; B represents a substituted or unsubstituted fluorenyl group; and Rrepresents hydrogen, an alkyl group having 1 to 6 carbon atoms, or an aryl group having 6 to 13 carbon atoms.
