To provide a novel heterocyclic compound that can be used as a host material in which a light-emitting substance of a light-emitting layer is dispersed. A heterocyclic compound comprising a dibenzo[f,h]quinoxaline ring and two hole-transport skeletons, where the dibenzo[f,h]quinoxaline ring and the two hole-transport skeletons are bonded to an aromatic hydrocarbon group. A heterocyclic compound represented by the following general formula (G1) is provided.
Note that in the formula, A
1
and A
2
each independently represent any of a substituted or unsubstituted carbazole skeleton, a substituted or unsubstituted dibenzofuran skeleton, and a substituted or unsubstituted dibenzothiophen skeleton; B represents a substituted or unsubstituted dibenzo[f,h]quinoxaline skeleton; and Ar represents an arene skeleton having 6 to 13 carbon atoms. A light-emitting element including the heterocyclic compound is provided.
提供一种新颖的杂环化合物,可用作其中光发射层的发光物质被分散的宿主材料。包括一个二苯并[f,h]喹喔啉环和两个传输空穴骨架的杂环化合物,其中二苯并[f,h]喹喔啉环和两个传输空穴骨架与芳香烃基结合。提供了由以下通用公式(G1)表示的杂环化合物。请注意,在该公式中,A1和A2分别独立表示任何取代或未取代的咔唑骨架、取代或未取代的二苯并呋喃骨架和取代或未取代的二苯并噻吩骨架;B表示取代或未取代的二苯并[f,h]喹喔啉骨架;Ar表示具有6至13个碳原子的芳香烃骨架。提供包括该杂环化合物的发光元件。
