Abstract
A high triplet energy hole transport material with pyrroloacridine core was synthesized and the device performances of green and blue phosphorescent organic light-emitting diodes were studied. The pyrroloacridine type hole transport material showed high triplet energy of 2.90 eV for triplet exciton blocking in phosphorescent organic light-emitting diodes. Green and blue PHOLEDs fabricated using the pyrroloacridine core based hole transport layer showed high quantum efficiency of 17.2% and 20.3%, respectively.
