Abstract

A novel heterocyclic compound is provided. A novel heterocyclic compound that can be used for a light-emitting element is provided. A novel heterocyclic compound that can improve the reliability of a light-emitting element when used for a light-emitting element is provided. A light-emitting element, a light-emitting device, an electronic appliance, or a lighting device which includes the novel heterocyclic compound and is highly reliable is provided. One embodiment of the present invention is a heterocyclic compound represented by a general formula (G0). In the general formula (G0), A represents a dibenzo[f,h]quinoxalinyl group, B represents a substituted or unsubstituted fluorenyl group, and Ar represents a substituted or unsubstituted arylene group having 6 to 25 carbon atoms.

A-Ar—B  (G0)

First claim

2. The compound according to claim 1 , wherein B is a substituted or unsubstituted 2-fluorenyl group.

3. The compound according to claim 1 ,
wherein B is represented by a formula (α):

and
wherein each of R 11 to R 19 independently represents hydrogen, an alkyl group having 1 to 6 carbon atoms, or an aryl group having 6 to 12 carbon atoms.

4. The compound according to claim 1 ,
wherein B is represented by a formula (β):

and
wherein each of R 17 and R 18 independently represents hydrogen, an alkyl group having 1 to 6 carbon atoms, or an aryl group having 6 to 12 carbon atoms.

5. The compound according to claim 1 ,
wherein the compound is represented by a formula (G1):

wherein one of R 1 to R 10 is represented by a formula (G1-1) and the others of R 1 to R 10 independently represent hydrogen or an alkyl group having 1 to 6 carbon atoms, and
wherein B represents a substituted or unsubstituted fluorenyl group, and Ar represents a substituted or unsubstituted arylene group having 6 to 25 carbon atoms.

6. The compound according to claim 5 , wherein B is a substituted or unsubstituted 2-fluorenyl group.

7. The compound according to claim 5 ,
wherein B is represented by a formula (α):

and
wherein each of R 11 to R 19 independently represents hydrogen, an alkyl group having 1 to 6 carbon atoms, or an aryl group having 6 to 12 carbon atoms.

8. The compound according to claim 5 ,
wherein B is represented by a formula (β):

and
wherein each of R 17 and R 18 independently represents hydrogen, an alkyl group having 1 to 6 carbon atoms, or an aryl group having 6 to 12 carbon atoms.
