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)
DBqAr1nAr2-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.
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。该杂环化合物由通式(G1)DBqAr1nAr2-A表示,在该通式(G1)中,通过一个取代或未取代的芳基烃基团将一个取代或未取代的二苯并[f,h]喹啉基团和一个取代或未取代的苯并苯并二呋喃基团连接在一起。在通式(G1)中,DBq代表一个取代或未取代的二苯并[f,h]喹啉基团,Ar1代表一个具有6至13个碳原子的取代或未取代的芳基烃基团,n代表0或1,Ar2代表一个具有6至13个碳原子的取代或未取代的芳基烃基团,A代表一个取代或未取代的苯并苯并二呋喃基团。当由Ar1和Ar2表示的芳基烃基团具有取代基时,这些取代基可以连接在一起形成环。
