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 JP6375302
Kind Code:
B2
Abstract:
Provided are a material for an organic EL device that improves the luminous efficacy of a device, sufficiently secures its driving stability, and has a simple construction, and an organic EL device using the material. The material for an organic EL device is formed of a carborane compound having a structure in which a dibenzofuranyl group is bonded to a carborane ring. In addition, the material for an organic EL device is preferably used in a light-emitting layer, an electron-transporting layer, or a hole-blocking layer of an organic electroluminescent device having the light-emitting layer between an anode and a cathode laminated on a substrate. Also disclosed is an organic electroluminescent device using the material for an organic EL device as a host material for a light-emitting layer containing a phosphorescent light-emitting dopant and the host material.
