摘要: A novel, bipolar polymeric host based on a poly(aryl ether) containing phosphine oxide units in the electron-transporting main chain and carbazole hole-transporting side chains is designed synthesized for blue electrophosphorescence. This possesses character high E(T) of 2.96 eV. The efficiency blue-emitting PhPLEDs this doped with Flrpic reaches 23.3 cd A(-1) (EQE = 10.8%).
