COMPOUND FOR ORGANIC ELECTROLUMINESCENT DEVICE AND ORGANIC ELECTROLUMINESCENT DEVICE

摘要

Disclosed is an organic electroluminescent device (organic EL device) having a simple structure, which is improved in luminous efficiency while securing sufficient driving stability. Also disclosed is a compound for organic EL devices used in such an organic electroluminescent device. Specifically disclosed is an organic electroluminescent device having organic layers including a light-emitting layer between an anode and a cathode arranged on a substrate, wherein at least one of the organic layers contains a compound for organic EL devices represented by the general formula (1) below. A light-emitting layer containing a phosphorescent dopant is preferable as such one of the organic layers. In the general formula (1) below, X represents a substituted or unsubstituted methine or a nitrogen; Ar-Arrepresent a substituted or unsubstituted aromatic hydrocarbon group or aromatic heterocyclic group; and Arand Aras well as Arand Armay form a nitrogen-containing heterocyclic ring together with a nitrogen atom which is bonded thereto.
