An anthracene derivative is disclosed, and a light-emitting element, a light-emitting device, an electronic device, and a lighting device using the anthracene derivatives are demonstrated. The structure of the anthracene derivative is described in detail in the specification. The use of the anthracene derivative enables the production of a blue emissive light-emitting element having high emission efficiency, excellent purity of emission color, and a long lifetime, which contributes to the production of a high-performance light-emitting device, electronic device, and lighting device.
A light-emitting element with high emission efficiency. The light-emitting element includes a pair of electrodes and an EL layer between the pair of electrodes. In the light-emitting element, the EL layer contains at least a light-emitting material, the light-emitting material is a 1,6-bis(diphenylamino)pyrene derivative, and a structural change between an excited state and a ground state in the 1,6-bis(diphenylamino)pyrene derivative is smaller than that in a 1,6-bis(diphenylamino)pyrene derivative in which hydrogen is bonded to ortho positions of two phenyl groups of each of two diphenylamino groups.
