By providing a novel polycyclic aromatic compound in which a plurality of aromatic rings are linked via a boron atom, a nitrogen atom, or the like, options of a material for an organic EL element are increased. In addition, by using the novel polycyclic aromatic compound as a material for an organic electroluminescent element, an excellent organic EL element is provided.
通过提供一种新型的多环芳香化合物,其中多个芳香环通过
硼原子、氮原子或类似物连接,增加了有机EL元件材料的选择。此外,通过将新型多环芳香化合物用作有机电致发光元件的材料,提供了优秀的有机EL元件。
