The present invention provides a novel polycyclic aromatic compound having a plurality of aromatic rings linked by a boron atom, a nitrogen atom, and the like, and thus increases the number of alternatives of a material for an organic electroluminescent (EL) device. Furthermore, the present invention provides an excellent organic EL device by using a novel polycyclic aromatic compound as a material for an organic EL device.
本发明提供了一种新型多环芳香化合物,其中多个芳香环由
硼原子、氮原子等连接,从而增加了有机电致发光(EL)器件材料的选择。此外,本发明通过使用新型多环芳香化合物作为有机EL器件的材料,提供了优秀的有机EL器件。
