Title:
MATERIAL FOR ORGANIC ELECTROLUMINESCENT ELEMENT, AND ORGANIC ELECTROLUMINESCENT ELEMENT USING SAME
Document Type and Number:
WIPO Patent Application WO/2011/125680
Kind Code:
A1
Abstract:
Disclosed is a material for an organic electroluminescent element, which has a specific structure wherein a dibenzothiophenyl group or a carbazolyl group is bonded directly or via a linking group at the N-position (the 9-position) of a carbazolyl group. Also disclosed is an organic electroluminescent element, which comprises one or more organic thin film layers including a light emitting layer between the negative electrode and the positive electrode, and which is characterized in that at least one organic thin film layer contains the above-described material for an organic electroluminescent element.
