Abstract:
The purpose of the present invention is to provide a compound which exhibits high luminous efficiency and excellent durability and has green light emission characteristics. The present invention is a compound which has a structure represented by general formula (1). In general formula (1), ring A1 and ring B1 are each a substituted or unsubstituted aromatic hydrocarbon ring having 6-30 ring-forming carbon atoms or a substituted or unsubstituted aromatic heterocyclic ring having 5-30 ring-forming atoms. Ring C1 is a substituted or unsubstituted polycyclic aromatic hydrocarbon having 11-20 ring-forming atoms. Ring D1 is a substituted or unsubstituted polycyclic aromatic hydrocarbon having 7-20 ring-forming atoms. X is O, N-RA or S, and RA is an alkyl group, a cycloalkyl group, an alkenyl group, an imino group, an aryl group or a heteroaryl group. These groups may have substituent groups. In addition, RA may bond to ring A1 or ring B1 via a linking group to form a ring. In this case, the linking group is a single bond, -O-, -S-, >CRA1RA2 or >SiA3RA4. RA1 to RA4 are each independently hydrogen, a halogen, an alkyl group, a cycloalkyl group, an aryl group or a heteroaryl group, and these groups may have substituent groups. In addition, RA1 and RA2 or RA3 and RA4 may be bonded via a linking group. L is a single bond, O, S, >CRA5RA6 or >SiRA7RA8. RA5 to RA8 are each independently selected from the group consisting of a hydrogen atom, a halogen atom, an alkyl group, a cycloalkyl group, an aryl group and a heteroaryl group, and these groups may have substituent groups. In addition, RA5 and RA6 may be bonded via a linking group, and RA7 and RA8 may be bonded via a linking group.
