Title:
MATERIAL FOR ORGANIC ELECTROLUMINESCENT ELEMENTS, AND ORGANIC ELECTROLUMINESCENT ELEMENT USING SAME
Document Type and Number:
WIPO Patent Application WO/2015/045718
Kind Code:
A1
Abstract:
Provided are: an organic electroluminescent element (organic EL element) which has simple configuration and improved luminous efficiency, while ensuring sufficient operational stability; and a material for organic EL elements which is used for this organic EL element.
A material for organic EL elements, which is composed of an ortho-carborane compound having a structure wherein a silyl group (-SiR3) is bonded to a divalent ortho-carborane group represented by C2B10H10 via an aromatic group. An organic electroluminescent element which is obtained by laminating a positive electrode, an organic layer and a negative electrode on a substrate, and wherein the organic layer contains the above-described ortho-carborane compound and serves as a light emitting layer, an electron transport layer, a hole blocking layer or an exciton blocking layer.
