  • Publication number: 20200144515
    Abstract: 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.

  • Publication number: 20190214575
    Abstract: Provided is an organic electroluminescent element which has improved driving voltage and improved current efficiency. An organic electroluminescent element having the above-mentioned improved characteristics is provided by using, as a material for organic electroluminescent elements, a polycyclic aromatic compound in which a nitrogen atom and another heteroatom or a metal atom (X) are adjacent to each other in a non-aromatic ring.
