ORGANIC ELECTROLUMINESCENT COMPOUND AND ORGANIC ELECTROLUMINESCENT DEVICE COMPRISING THE SAME

Document Type and Number:

WIPO Patent Application WO/2020/054989

Kind Code:

A1

Abstract:

The present disclosure relates to an organic electroluminescent compound represented by formula 1 and an organic electroluminescent device comprising the same. By comprising the organic electroluminescent compound of the present disclosure having good thermal stability, it is possible to provide an organic electroluminescent device having lower driving voltage, higher luminous efficiency and/or longer lifetime properties as compared with a conventional organic electroluminescent device.
