Organic Compound, Light-Emitting Element, Light-Emitting Device, Electronic Device, and Lighting Device

Abstract

To provide a novel fluorescent organic compound (a fluorescent compound). The organic compound is a substance that emits fluorescence and an organic compound (a host material) in which FIA can occur efficiently. In the organic compound, triplet excitons, which do not contribute to light emission, can be efficiently converted into singlet excitons. The use of such an organic compound can increase emission efficiency of a light-emitting element.
