| abstract |
The present invention provides a light-emitting element with high luminous efficacy and reliability. Specifically provided is a light-emitting element comprising, in a light-emitting layer, a light-emitting material and a material that acts as an energy donor. The material that acts as an energy donor functions to convert triplet excitation energies into light emission, and the light-emitting material produces fluorescence. The molecular structure of the light-emitting material is a structure having a luminophore and protecting groups, and at least five protecting groups are included in one molecule of a guest material. By introducing the protecting groups to the molecule, Dexter energy transfer of triplet excitation energies from the material that acts as an energy donor to the light-emitting material is suppressed. Alkyl groups or branched alkyl groups are used as the protecting groups. Light emission can be obtained from both the light-emitting material and the material that acts as an energy donor. |
