2-(PHENYLSULFONYL)PYRIDINE DERIVATIVES AND ORGANIC ELECTROLUMINESCENT DEVICE COMPRISING SAME

摘要

The present invention relates to 2-(phenysulfonyl)pyridine derivatives represented by the following chemical formula 1 and an organic light emitting diode having excellent efficiency by comprising the same 2-(phenysulfonyl)pyridine derivatives in one or more organic layers. The 2-(phenysulfonyl)pyridine derivatives and the organic light emitting diode comprising the same according to the present invention are excellent in luminous efficiency and heat stability and applicable to all luminous layers ranging between red and blue phosphorescence, thereby being able to be used in various organic light emitting diodes for a flat panel display of a wall-mountable TV, lights, or a backlight of a display. [Chemical formula 1] In the chemical formula 1, R1 is anyone selected from the group comprised of phenyl, dibenzo[b,d]furanyl, and dibenzo [b,d]thienyl, and R2 is anyone selected from the group comprised of tert-butyl, trimethylsilanyl, phenyl, and mesityl.
