A novel polycyclic aromatic compound in which plural aromatic rings are linked via boron atoms, oxygen atoms and the like is provided, and therefore, the range of selection of the material for organic electroluminescent elements can be widened. Also, an excellent organic electroluminescent element is provided by using the novel polycyclic aromatic compound as a material for an organic electroluminescent element.
提供了一种新的多环芳香化合物,其中多个芳香环通过
硼原子、氧原子等连接。因此,有机电致发光元件材料的选择范围可以扩大。同时,通过使用新的多环芳香化合物作为有机电致发光元件的材料,提供了一种优秀的有机电致发光元件。
