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.
提供了一种新的杂环化合物。具体来说,提供了一种可以改善发光元件特性的新型杂环化合物。提供了一种具有高发射效率和高耐热性的新型发光元件。由通用式(G1)表示的杂环化合物。A代表二苯并噻吩基团、二苯并呋喃基团和咔唑基团中的任意一种。DBq代表二苯并[f,h]喹喔啉基团。此外,n为0或1。Ar1至Ar4中的每一个独立地表示具有6到10个碳原子的取代或未取代芳基基团。在Ar1至Ar4中,相邻的芳基基团可以相互连接形成环。当Ar1至Ar4中的相邻芳基基团形成芴骨架时,芴骨架可以有取代基。
