Abstract: A novel heterocyclic compound is provided. In particular, a novel heterocyclic compound which can improve the element characteristics of a light-emitting element is provided. A novel light-emitting element with high emission efficiency and high heat resistance is provided. A heterocyclic compound represented by General Formula (G1). A represents any of a dibenzothiophenyl group, a dibenzofuranyl group, and a carbazolyl group. DBq represents a dibenzo[f,h]quinoxalinyl group. In addition, n is 0 or 1. Each of Ar1 to Ar4 independently represents a substituted or unsubstituted arylene group having 6 to 10 carbon atoms. In Ar1 to Ar4, the adjacent arylene groups may be bonded to each other to form a ring. When the adjacent arylene groups in Ar1 to Ar4 form a fluorene skeleton, the fluorene skeleton may have a substituent.

Abstract: A novel heterocyclic compound is provided. In particular, a novel heterocyclic compound which can improve the element characteristics of the light-emitting element is provided. The heterocyclic compound is represented by a general formula (G1) DBq-(Ar1)-n-Ar2-A   (G1) in which a substituted or unsubstituted dibenzo[f,h]quinoxalinyl group and a substituted or unsubstituted benzobisbenzofuranyl group are bonded to each other via a substituted or unsubstituted arylene group. In the general formula (G1), DBq represents a substituted or unsubstituted dibenzo [f,h] quinoxalinyl group, Ar1 represents a substituted or unsubstituted arylene group having 6 to 13 carbon atoms, n represents 0 or 1, Ar2 represents a substituted or unsubstituted arylene group having 6 to 13 carbon atoms, and A represents a substituted or unsubstituted benzobisbenzofuranyl group. When the arylene group represented by Ar1 and Ar2 has substituents, the substituents may be bonded to each other to form a ring.

Abstract translation: 其中取代或未取代的二苯并[f，h]喹喔啉基和取代或未取代的苯并二苯并呋喃基经由取代或未取代的亚芳基彼此键合。 在通式（G1）中，DBq表示取代或未取代的二苯并[f，h]喹喔啉基，Ar 1表示取代或未取代的碳原子数6〜13的亚芳基，n表示0或1，Ar 2表示取代或未取代的 具有6至13个碳原子的亚芳基，A表示取代或未取代的苯并二苯并呋喃基。 当由Ar 1和Ar 2表示的亚芳基具有取代基时，取代基可以彼此键合形成环。
