    摘要: Electroluminescent devices are disclosed comprising a transparent anode; a layer of a hole transporting material; a layer of an electroluminescent material; a layer of an electron transporting material; a layer of a substituted lithium quinolate; and a metal cathode. The electroluminescent device may be an organic light-emitting diode having a cathode, an electron injection layer in contact with the cathode and an electron transport layer in contact with the electron injection layer and comprising aluminum, zirconium or hafnium quinolate or a mixture thereof or a mixture of any of them with a quinolate of a metal of group 1, 2, 3, 13 or 14 of the periodic table. Such devices may be made by the steps of forming a substituted lithium quinolate having one or more substituents and depositing the substituted lithium quinolate on a cathode of the device to provide an electron injection layer.
