A bipolar host material with a phenyl‐modified acridine core and a pyridine unit in the molecular structure was synthesized as the host material for green phosphorescent organic light‐emitting diodes (PHOLEDs). A high triplet energy of 2.76 eV was obtained from the host and a high quantum efficiency of 13.5 % was achieved in green PHOLEDs using the acridine‐based host material.
