Abstract
The present invention relates to an anthracene derivative and an organic electroluminescent device using the same. More specifically, the present invention relates to: a novel compound which has a core (for example, an indenoanthracene core) where both an anthracene moiety with excellent device characteristics and a fluorene moiety with excellent fluorescent properties are fused, wherein substituents (for example, a heterocyclic group such as a benzimidazole group, a benzothiazole group, a benzoxazole group, a pyridinyl group or a bipyridinyl group) with an electron transfer capacity are substituted to the core; and an organic electroluminescence element which has improved luminous efficiency, brightness, thermal stability, driving voltage, and lifetime, by comprising an organic layer which is positioned between a positive electrode and negative electrode and contains the novel compound.
