NOVEL ORGANIC ELECTROLUMINESCENCE COMPOUNDS AND ORGANIC ELECTROLUMINESCENCE DEVICE CONTAINING THE SAME

摘要

The present invention relates to novel organic electroluminescent compounds and an organic electroluminescent device comprising the same. The organic electroluminescent compounds according to the present invention have high luminescent efficiency and a long lifespan, and thus an organic electroluminescent device having a long operating lifespan can be prepared by using the organic electroluminescent compounds according to the present invention.
