ASYMMETRIC PYRENE DERIVATIVE AND ORGANIC ELECTROLUMINESCENT DEVICE USING SAME

Title:

ASYMMETRIC PYRENE DERIVATIVE AND ORGANIC ELECTROLUMINESCENT DEVICE USING SAME

Document Type and Number:

WIPO Patent Application WO/2005/115950

Kind Code:

A1

Abstract:

Disclosed are asymmetric pyrene derivatives having a specific structure. An organic electroluminescent device comprising an organic thin film layer which is interposed between an anode and a cathode and composed of one or more layers including at least a light-emitting layer is also disclosed wherein the organic thin film layer contains at least one of the asymmetric pyrene derivatives by itself or as a component of a mixture. Such an organic electroluminescent device has high luminous efficiency and long life due to the asymmetric pyrene derivative.
