Compound, light-emitting element, display device, electronic device, and lighting device
A compound includes a benzofuropyrimidine skeleton or a benzothienopyrimidine skeleton, a first substituent, and a second substituent. Each of the first substituent and the second substituent includes a furan skeleton, a thiophene skeleton, or a pyrrole skeleton. The first substituent is bonded to a pyrimidine ring included in the benzofuropyrimidine skeleton or a pyrimidine ring included in the benzothienopyrimidine skeleton. The second substituent is bonded to a benzene ring included in the benzofuropyrimidine skeleton or a benzene ring included in the benzothienopyrimidine skeleton. The light-emitting element includes the compound.
1. A light-emitting element comprising a compound,
wherein the compound comprises a skeleton that is one of a benzofuropyrimidine skeleton and a benzothienopyrimidine skeleton; a first substituent; and a second substituent,
wherein the first substituent comprises any of a furan skeleton and a thiophene skeleton,
wherein the second substituent comprises any of a furan skeleton, a thiophene skeleton, and a pyrrole skeleton,
wherein the first substituent is bonded to a pyrimidine ring of the skeleton,
wherein the second substituent is bonded to a benzene ring of the skeleton,
wherein the skeleton is one of a benzofuro[3,2-d]pyrimidine skeleton and a benzothieno[3,2-d]pyrimidine skeleton,
wherein the first substituent is bonded to the 2- or 4-position of the skeleton, and
wherein the second substituent is bonded to the 6-, 7-, 8-, or 9-position of the skeleton.
2. The light-emitting element according to claim 1 ,
wherein the skeleton is one of a benzofuro[3,2-d]pyrimidine skeleton and a benzothieno[3,2-d]pyrimidine skeleton;
wherein the first substituent is bonded to the 4-position of the skeleton, and
wherein the second substituent is bonded to the 8-position of the skeleton.
3. The light-emitting element according to claim 1 ,
wherein each of the first substituent and the second substituent comprises a furan skeleton or each of the first substituent and the second substituent comprises a thiophene skeleton.
4. The light-emitting element according to claim 1 ,
wherein the first substituent comprises any of a dibenzofuran skeleton and a dibenzothiophene skeleton, and
wherein the second substituent comprises any of a dibenzofuran skeleton, a dibenzothiophene skeleton, and a carbazole skeleton.
5. The light-emitting element according to claim 1 ,
wherein each of the first substituent and the second substituent comprises a dibenzofuran skeleton or each of the first substituent and the second substituent comprises a dibenzothiophene skeleton.
6. The light-emitting element according to claim 1 ,
wherein the first substituent and the second substituent are the same substituent.
