PYRENE-BASED COMPOUND AND ORGANIC LIGHT EMITTING DIODE COMPRISING THE SAME

摘要

Disclosed are a pyran-based compound having a new structure, and an organic light emitting device comprising the same. The pyran-based compound of the present invention is represented by the following chemical formula 1. An organic light emitting device comprising the pyran-based compound comprises a first electrode, a second electrode which is opposite to the first electrode, and an organic layer located between the first electrode and the second electrode, and comprising a light emitting layer, thereby, having a low driving voltage, a high brightness, a high efficiency, and a long lifetime.
