Abstract

Disclosed are an organic electroluminescent device (organic EL device) having improved luminous efficiency, sufficiently secured driving stability, and a simple construction, and a material for an organic EL device. The material for an organic EL device includes a carborane compound having a structure in which at least one carborane ring and at least one dibenzothiophene ring are present, and the at least one carborane ring is bonded to the at least one dibenzothiophene ring at position 1, 2, or 3. In addition, the organic EL device includes, between an anode and a cathode laminated on a substrate, at least one organic layer, in which the at least one organic layer includes the carborane compound.
