COMPOUND FOR ORGANIC ELECTROLUMINESCENT DEVICE AND ORGANIC ELECTROLUMINESCENT DEVICE USING THE SAME |
摘要 |
<p>Disclosed is an organic electroluminescent device (organic EL device) of a simple structure, which has improved luminous efficiency and sufficient driving stability. Also disclosed is a compound for organic electroluminescent devices which is used in the organic electroluminescent device. Specifically disclosed is a compound for organic electroluminescent devices which is a bipyrimidyl compound having 2,2'-bipyrimidyl as a basic skeleton, while comprising an aromatic hydrocarbon group, an aromatic heterocyclic group or a substituted amino group as a substituent. Also specifically disclosed is an organic electroluminescent device comprising a light-emitting layer between an anode and a cathode laminated on a substrate, wherein the light-emitting layer contains a phosphorescent dopant and the bipyrimidyl compound which serves as a host material.</p> |
