摘要：

A new bipolar host material (PBCz-PO) consisting a phosphinic amide is developed to show a resonance effect. It possesses quite high triplet energy (2.76 eV), and this high triplet energy make it suitable to be blue host in phosphorescent organic light-emitting diodes (PHOLEDs).  The device with PBCz-PO as a host and FIrpic as a dopant achieved a  maximum current efficiency (η_c) of 31.5 cd/A, a maximum power efficiency (η_p) of 31.0 lm/W and a maximum external quantum  efficiency (EQE) of 13.4% as well as low driving voltage.
