Patent ID: 10468608

Abstract:
Provided are an organic EL device having high efficiency and high driving stability, and a compound suitable for the device. Provided is a material for an organic electroluminescent device formed of a carborane compound having a structure in which: one or two boron atoms of a carborane ring C2B10H12 are substituted with an aromatic hydrocarbon group or an aromatic heterocyclic group; and the two carbon atoms of the carborane ring are each bonded to an aromatic hydrocarbon group or an aromatic heterocyclic group, or are each bonded to any other carborane ring when a plurality of carborane rings are present. Also provided is an organic electroluminescent device in which the material for an organic electroluminescent device is used in a light-emitting layer, an electron-transporting layer, or a hole-blocking layer.
