摘要：

High efficiency blue electroluminescence is demonstrated from a polyquinoline ether, a new class of soluble, electroluminescent, polyaromatic polymer. Multilayer devices (consisting of hole and electron transport layers in addition to the emissive polyquinoline layer) show an internal quantum efficiency in excess of 4% at 450 nm. Light emitted from these devices is easily visible in room light with luminence levels of 30 cd/m2 at 55 V with a current density of 9 mA/cm2. The transport layers are shown to serve a dual function-to modify the carrier injection properties and to block passage of carriers of the opposite polarity thereby trapping carriers in the emissive layer.
