Six novel 2,5-bis[4-(2-arylvinyl)phenyl]-1,3,4-oxadiazoles were designed and synthesized through Wittig-Horner reaction by embedding electron-transporting 1,3,4-oxadiazole in PPV oligomer, which are one kind of blue luminescence materials with highly hole injection, and their chemical structures were also determined to show trans-vinylene character according to IR and 1H NMR spectra.
二乙烯联苯及其衍生物是一种可发射蓝光的小分子空穴型有机发光材料,通过Wittig-Horner反应,将电子传输型噁二唑环“嵌入”其中,设计合成了6个2,5-二[4-(2-芳基乙烯基)苯基]-1,3,4-噁二唑化合物。

Horner反应
1.
2,5-Dicyano-4-[(diethoxyphosphoryl)methyl]-4′-(N,N-diphenyl)aminostilbene, a key intermediate of organic two-photon absorption material, was synthesized by NBS bromization, Abuzov reaction and Horner reaction.
以2,5-二氰基对二甲苯为起始原料,通过NBS溴化,Abuzov和Horner反应合成了一种D-π-A型不对称有机双光子吸收材料的关键中间体2,5-二氰基-4-[(二乙氧基磷酰)甲基]-4′-(N,N-二苯基)氨基二苯乙烯,其结构经NMR,IR和MS表征。
补充资料:Horner Emmons reaction
分子式:
CAS号:

性质:又称沃兹沃思-埃蒙斯反应(Wadsworth-Emmons reaction),霍纳-埃蒙斯反应(Horner Emmons reaction)。是维蒂希反应的改进。卤代烃与三烷氧基磷反应生成膦酸酯,在碱的作用下与羰基化合物反应生成烯烃。与维蒂希反应比较,碳负离子反应性高,制备方便,生成的膦酸盐易除去,有利于烯烃的提纯。常用的溶剂有二噁烷、二甲基甲酰胺、四氢呋喃等。常用的碱与维蒂希反应所用的相同。
