, (2014/06/24)
A nitrogen-containing aromatic heterocyclic derivative in which a nitrogen atom of an indenocarbazole skeleton optionally having a hetero atom or an indenoindole skeleton optionally having a hetero atom is bonded to a dibenzofuran or a dibenzothiophene directly or indirectly. The derivative realizes an organic EL device with a high emission efficiency and a long lifetime.
