COMPOUND FOR ORGANIC ELECTROLUMINESCENT DEVICE AND ORGANIC ELECTROLUMINESCENT DEVICE

摘要

Disclosed is an organic electroluminescent device (organic EL device) having a simple constitution, which is improved in luminous efficiency, while sufficiently securing driving stability. Also disclosed is a compound for organic EL devices, which is used in such an organic electroluminescent device. Specifically disclosed is an organic electroluminescent device, which comprises organic layers including a light-emitting layer between an anode and a cathode arranged on the substrate. In this organic electroluminescent device, one of the organic layers contains a compound represented by the general formula (1) below. The organic layer containing a compound represented by the general formula (1) below is preferably a light-emitting layer containing a phosphorescent dopant. In the general formula (1) below, X represents CR or N; Ar₁-Ar₃ each represents a substituted or unsubstituted aromatic hydrocarbon group or aromatic heterocyclic group, and Ar₂ and Ar₃ may form a nitrogen-containing heterocyclic ring together with a nitrogen atom to which they are bonded; and m and n each represents an integer of 1 or 2, and the sum of m and n is 3.
