Abstract

Provided is a novel heterocyclic compound which can be used for a light-emitting element, as a host material of a light-emitting layer in which a light-emitting substance is dispersed. A heterocyclic compound represented by a general formula (G1) is provided. In the formula, A represents any of a substituted or unsubstituted dibenzothiophenyl group, a substituted or unsubstituted dibenzofuranyl group, and a substituted or unsubstituted carbazolyl group, R 11 to R 19 separately represent any of hydrogen, an alkyl group having 1 to 4 carbon atoms, and a substituted or unsubstituted aryl group having 6 to 14 carbon atoms, and Ar represents a substituted or unsubstituted arylene group having 6 to 13 carbon atoms.

First claim

What is claimed is:

1. A heterocyclic compound represented by a general formula (G1),

wherein A represents a substituted or unsubstituted dibenzothiophenyl group or a substituted or unsubstituted dibenzofuranyl group, a substituent of the substituted dibenzothiophenyl group and the substituted dibenzofuranyl group being any of an alkyl group having 1 to 4 carbon atoms and an aryl group having 6 to 14 carbon atoms,
wherein R 11 to R 19 separately represent any of hydrogen, an alkyl group having 1 to 4 carbon atoms, and an aryl group having 6 to 14 carbon atoms, and
wherein Ar represents a substituted or unsubstituted arylene group having 6 to 13 carbon atoms, a substituent of the substituted arylene group being any of an alkyl group having 1 to 4 carbon atoms and an aryl group having 6 to 14 carbon atoms.

2. The heterocyclic compound according to claim 1 , wherein Ar is a biphenyldiyl group.

3. The heterocyclic compound according to claim 1 , wherein Ar is a phenylene group.

4. The heterocyclic compound according to claim 1 , wherein Ar is an m-phenylene group.

5. A heterocyclic compound represented by a general formula (G2-1),

wherein Q 1 represents a sulfur atom or an oxygen atom,
wherein R 11 to R 19 and R 21 to R 27 separately represent any of hydrogen, an alkyl group having 1 to 4 carbon atoms, and an aryl group having 6 to 14 carbon atoms, and
wherein Ar represents a substituted or unsubstituted arylene group having 6 to 13 carbon atoms, a substituent of the substituted arylene group being any of an alkyl group having 1 to 4 carbon atoms, and an aryl group having 6 to 14 carbon atoms.

6. The heterocyclic compound according to claim 5 , wherein Ar is a biphenyldiyl group.

7. The heterocyclic compound according to claim 5 , wherein Ar is a phenylene group.

8. The heterocyclic compound according to claim 5 , wherein Ar is an m-phenylene group.

9. A heterocyclic compound represented by a general formula (G2-3),

wherein Q 2 represents a sulfur atom or an oxygen atom,
wherein R 11 to R 19 and R 41 to R 47 separately represent any of hydrogen, an alkyl group having 1 to 4 carbon atoms, and an aryl group having 6 to 14 carbon atoms, and
wherein Ar represents a substituted or unsubstituted arylene group having 6 to 13 carbon atoms, a substituent of the substituted arylene group being any of an alkyl group having 1 to 4 carbon atoms, and an aryl group having 6 to 14 carbon atoms.

10. The heterocyclic compound according to claim 9 , wherein Ar is a biphenyldiyl group.

11. The heterocyclic compound according to claim 9 , wherein Ar is a phenylene group.

12. The heterocyclic compound according to claim 9 , wherein Ar is an m-phenylene group.

13. A heterocyclic compound represented by a general formula (G3-1),

wherein Q 1 represents a sulfur atom or an oxygen atom, and
wherein R 11 to R 19 , R 21 to R 27 , and R 51 to R 54 separately represent any of hydrogen, an alkyl group having 1 to 4 carbon atoms, and an aryl group having 6 to 14 carbon atoms.

14. A heterocyclic compound represented by a general formula (G3-3),

wherein Q 2 represents a sulfur atom or an oxygen atom, and
wherein R 11 to R 19 , R 41 to R 47 , and R 51 to R 54 separately represent any of hydrogen, an alkyl group having 1 to 4 carbon atoms, and an aryl group having 6 to 14 carbon atoms.

15. A light-emitting element comprising the heterocyclic compound according to claim 1 .

16. A light-emitting device comprising the light-emitting element according to claim 15 .

17. An electronic device comprising the light-emitting element according to claim 15 .

18. A lighting device comprising the light-emitting element according to claim 15 .

19. The heterocyclic compound according to claim 5 , wherein the heterocyclic compound is represented by a chemical formula (101) or (107)

20. The heterocyclic compound according to claim 5 , wherein the heterocyclic compound is represented by a chemical formula (105) or (111)
