PHOSPHORYL SUBSTITUTED TRIAZINE DERIVATIVES AND ORGANIC ELECTROLUMINESCENT DEVICE INCLUDING THE SAME

摘要

Provided is triazine derivative bonded with a phosphoryl group. The trazine derivative is represented by chemical formula 1. In chemical formula 1, the definition of each substituent group is as same as in the specification. Provided are novel triazine derivative having excellent current density and durability in comparison to a conventional material, and an organic electroluminescent device comprising the same. The organic electroluminescent device has low operating voltage and improved luminescence efficiency while having long lifespan.
