Abstract
Our novel blue phosphorescent platinum complexes (BD‐01 and BD‐02) achieve high quantum yield and orientation. A BD‐02 organic light‐emitting diode (OLED) achieves an external quantum efficiency of 28.6% due to its inhibited interaction with a host molecule. This improved efficiency reduces the driving current of OLEDs and increases their lifetime.
