A polycyclic aromatic compound in which a plurality of aromatic rings are connected by a boron atom and an oxygen atom, a sulfur atom or a selenium atom and substituted by a specific aryl such as anthracene, is useful as a material for an organic device. By the polycyclic aromatic compound, an organic EL device having at least one of efficiency and device life can be provided.
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.
