PHOSPHORYL SUBSTITUTED TRIAZINE DERIVATIVES AND ORGANIC ELECTROLUMINESCENT DEVICE INCLUDING THE SAME

摘要

The present invention relates to phosphoryl group bonded triazine derivatives represented by chemical formulas 1 and 2. In the chemical formulas 1 and 2, the definitions of the substituent groups are the same as defined in the specification. The triazine derivatives have excellent current density and durability in comparison to a conventional material. The organic electroluminescent device has reduced driving voltage, improved luminous efficiency, and extended lifespan.
