Title:
有機電界発光素子用材料及びこれを用いた有機電界発光素子
Document Type and Number:
Japanese Patent JP6402177
Kind Code:
B2
Abstract:
Disclosed is an organic electroluminescent device (organic EL device) that is improved in luminous efficiency, sufficiently secures driving stability, and has a simple construction. The device is an organic electroluminescent device having organic layers including a light-emitting layer between an anode and a cathode laminated on a substrate, in which a carborane compound is incorporated into at least one layer of the organic layers, or is incorporated as a host material into a light-emitting layer containing a phosphorescent light-emitting dopant and the host material. The carborane compound has a structure in which a N-containing fused aromatic ring is bonded to a carborane ring. The N-containing fused aromatic ring is a quinoline ring or has a structure obtained by substituting 1 to 3 ring-forming carbon atoms in a quinoline ring with N atoms.
