COMPOUND FOR ORGANIC ELECTROLUMINESCENT DEVICE AND ORGANIC ELECTROLUMINESCENT DEVICE USING THE SAME

摘要

Disclosed is an organic electroluminescent device (organic EL device) which is improved in luminous efficiency, fully secured of driving stability, and of simple constitution. Also disclosed is a compound useful for the fabrication of said organic electroluminescent device. This compound for organic electroluminescent device is a bipyrimidyl compound which has a basic skeleton of 2,2'-bipyrimidyl and is substituted by an aromatic hydrocarbon group, an aromatic heterocyclic group, or a substituted amino group. The aforementioned organic electroluminescent device has a light-emitting layer between an anode and a cathode which are piled one upon another on a substrate and the light-emitting layer contains a phosphorescent dopant and the aforementioned bipyrimidyl compound as a host material.
