Abstract

A novel organic compound is provided. Moreover, a light-emitting element with high emission efficiency and a long lifetime is provided. A novel organic compound having a bicarbazole skeleton and a benzofuropyrimidine skeleton or a benzothienopyrimidine skeleton that includes at least one condensed ring or two condensed rings is provided. Moreover, a light-emitting element including the organic compound is provided.

Claims (24)

1. An organic compound represented by General Formula (G0):

wherein A represents a substituted or unsubstituted benzofuro[3,2-d]pyrimidine skeleton having a carbazole ring as a substituent; each of R 1 to R 15 independently represents any of hydrogen, an alkyl group having 1 to 6 carbon atoms, a substituted or unsubstituted cycloalkyl group having 3 to 7 carbon atoms, and a substituted or unsubstituted aryl group having 6 to 13 carbon atoms;

and Ar represents a substituted or unsubstituted arylene group having 6 to 25 carbon atoms, or a single bond.

2. The organic compound according to claim 1 , wherein the Ar is bonded to a 4-position of the benzofuro[3,2-d]pyrimidine skeleton.

3. The organic compound according to claim 1 , the organic compound is represented by General Formula (G1):

wherein Q represents oxygen; any one of R 16 to R 20 represents a substituent having a carbazole ring as a substituent and each of the others independently represents any of hydrogen, a substituted or unsubstituted alkyl group having 1 to 6 carbon atoms, a substituted or unsubstituted cycloalkyl group having 3 to 7 carbon atoms, and a substituted or unsubstituted aryl group having 6 to 13 carbon atoms.

4. An organic compound represented by General Formula (G2):

wherein Q represents oxygen; each of R 1 to R 19 independently represents any of hydrogen, an alkyl group having 1 to 6 carbon atoms, a substituted or unsubstituted cycloalkyl group having 3 to 7 carbon atoms, and a substituted or unsubstituted aryl group having 6 to 13 carbon atoms; Ar represents a substituted or unsubstituted arylene group having 6 to 25 carbon atoms, or a single bond; and B represents a substituent having a carbazole ring as a substituent.

5. The organic compound according to claim 4 , the organic compound is represented by General Formula (G3):

6. The organic compound according to claim 5 , the organic compound is represented by General Formula (G4):

wherein each of R 20 to R 27 independently represents any of hydrogen, an alkyl group having 1 to 6 carbon atoms, a substituted or unsubstituted cycloalkyl group having 3 to 7 carbon atoms, and a substituted or unsubstituted aryl group having 6 to 13 carbon atoms.

7. The organic compound according to claim 6 , the organic compound is represented by General Formula (G6):

8. A light-emitting element comprising:

a pair of electrode; and

a layer provided between the pair of electrode, the layer comprises an organic compound represented by General Formula (G0),

wherein A represents a substituted or unsubstituted benzofuro[3,2-d]pyrimidine skeleton having a carbazole ring as a substituent; each of R 1 to R 15 independently represents any of hydrogen, an alkyl group having 1 to 6 carbon atoms, a substituted or unsubstituted cycloalkyl group having 3 to 7 carbon atoms, and a substituted or unsubstituted aryl group having 6 to 13 carbon atoms;

and Ar represents a substituted or unsubstituted arylene group having 6 to 25 carbon atoms, or a single bond.

9. The light-emitting element according to claim 8 ,

wherein the Ar is bonded to a 4-position of the benzofuro[3,2-d]pyrimidine skeleton.

10. The light-emitting element according to claim 8 , the light-emitting element is configured to emit light containing a component including delayed fluorescence.

11. The light-emitting element according to claim 8 , further comprising a phosphorescent material.

12. A light-emitting device comprising:

a light-emitting portion comprising the light-emitting element according to claim 8 ; and

a substrate.
