　　A series of nitrogen heterocycle-containing electron-transport materials(ETMs)and host materials were developed for the FIrpic-based blue phosphorescent organic light-emitting diodes(OLEDs).Their HOMO and LUMO energy levels could be tuned by the different nitrogen heterocycles as well as their nitrogen atom orientation.
