Abstract

An organic light-emitting device comprising an anode, a cathode, and an emissive layer between the anode and cathode, wherein either the emissive layer is an oligo(phenylenevinylene) or derivative thereof is described. The device may further include a hole transport layer and/or an electron transport layer coupled with either the anode or cathode. Also described are displays employing such devices and a method of making such a device.
