Abstract:
A novel compound in which a delayed fluorescence component due to TTA accounts for a high proportion of emissive components is provided. The organic compound includes an anthracene skeleton, an arylene group, and a substituted or unsubstituted heterocyclic group including a carbazole skeleton. The anthracene skeleton and the substituted or unsubstituted heterocyclic group including the carbazole skeleton are bonded to each other through the arylene group. The anthracene skeleton includes an aryl group at the 2-position or the 3-position.
