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 13 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 compound represented by a general formula (G1),

wherein:
A represents any one of a substituted or unsubstituted dibenzothiophenyl group and a substituted or unsubstituted dibenzofuranyl group;
R 11 to R 19 separately represent any one of hydrogen, an alkyl group having 1 to 4 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 13 carbon atoms.

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

wherein:
Q 1 represents any one of a sulfur atom, an oxygen atom, and a nitrogen atom;
R 11 to R 19 and R 21 to R 27 separately represent any one of hydrogen, an alkyl group having 1 to 4 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 13 carbon atoms.

3. The compound according to claim 2 , wherein the nitrogen atom has an alkyl group having 1 to 4 carbon atoms, or a substituted or unsubstituted aryl group having 6 to 13 carbon atoms.

4. The compound according to claim 2 , wherein Ar is a substituted or unsubstituted phenylene group or a substituted or unsubstituted biphenyldiyl group.

5. The compound according to claim 2 , wherein Ar is a substituted or unsubstituted m-phenylene group.

6. The compound according to claim 2 ,
wherein:
the compound is represented by a general formula (G3-1); and

wherein:
R 51 to R 54 separately represent any one of hydrogen, an alkyl group having 1 to 4 carbon atoms; and a substituted or unsubstituted aryl group having 6 to 13 carbon atoms.

7. The compound according to claim 6 , wherein the nitrogen atom has an alkyl group having 1 to 4 carbon atoms, or a substituted or unsubstituted aryl group having 6 to 13 carbon atoms.

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

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

9. The compound according to claim 8 , wherein the nitrogen atom has an alkyl group having 1 to 4 carbon atoms, or a substituted or unsubstituted aryl group having 6 to 13 carbon atoms.

10. The compound according to claim 8 , wherein Ar is a substituted or unsubstituted phenylene group or a substituted or unsubstituted biphenyldiyl group.

11. The compound according to claim 8 , wherein Ar is a substituted or unsubstituted m-phenylene group.

12. The compound according to claim 8 ,
wherein:
the compound is represented by a general formula (G3-3); and

R 51 to R 54 separately represent any one of hydrogen, an alkyl group having 1 to 4 carbon atoms, and a substituted or unsubstituted aryl group having 6 to 13 carbon atoms.

13. The compound according to claim 12 , wherein the nitrogen atom has an alkyl group having 1 to 4 carbon atoms or a substituted or unsubstituted aryl group having 6 to 13 carbon atoms.
