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