Provided is an organic electroluminescence element having superior element service life. An anthracene compound in which an aryl group having C10 or greater is bonded to the 9-position and a naphthyl group is bonded to the 10-position, wherein a compound in which a specific aryl group has been substituted, in particular, at the 7-position of the naphthyl group (which is bonded at the 2-position thereof to the anthracene) is used as a material for a luminescence layer to produce the organic electroluminescence element.
提供的是具有优越元件使用寿命的有机电致发光元件。该元件采用一种蒽化合物,其中在9位上连接有具有C10或更多碳的芳基基团,而在10位上连接有萘基团。其中,使用一种特定芳基基团在萘基团的7位(其在2位处与蒽相连)被取代的化合物作为发光层材料,以制造有机电致发光元件。
