    摘要： In OLEDs, improved efficiency is obtained by using compounds of formula [Ar](CH═CH—R1)n wherein n is an integer from 1 to 4; [Ar] is a polycyclic aromatic or heteroaromatic scaffold optionally substituted with one or more alkyl or alkoxy groups; and R1 is a 5-membered heteroaryl group optionally substituted with methyl, methoxy, aryl or heteroaryl, or is phenyl or naphthyl optionally substituted with methyl, methoxy, trifluoromethyl or cyano or is biphenyl or substituted biphenyl. The compounds are believed to be novel and can be made by condensing a compound of formula wherein [Ar] and n are as defined above with a compound of formula [Ar](CH3)nR1CHO in the presence of an acid catalyst e.g. an anhydride of an organic acid.

    摘要翻译： 在OLED中，通过使用式[Ar]（CH = CH-R 1）n的化合物，其中n是1至4的整数，可以获得提高的效率; [Ar]是任选被一个或多个烷基或烷氧基取代的多环芳族或杂芳族支架; 并且R 1是任选被甲基，甲氧基，芳基或杂芳基取代的5元杂芳基，或者是被甲基，甲氧基，三氟甲基或氰基任选取代的苯基或萘基，或是联苯基或取代的联苯基。 这些化合物被认为是新的，并且可以通过在酸催化剂的存在下将下式化合物其中[Ar]和n如上所定义的化合物与式[Ar]（CH 3）n R 1 CHO的化合物缩合制备。 有机酸的酸酐。

    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.
