摘要:有机多孔聚合物是一类具有较大比表面积和永久孔结构的新型多孔材料。 它的制备方法多种多样、孔径可以调控、表面可以修饰,这些特点使它在气体吸附、储能、非均相催化等方面具有非常大的应用价值,因此,近年来有关有机多孔聚合物的研究的发展速度十分迅猛,成为一大热点。本课题合成了基于1,4-二溴苯的多孔聚合物。利用单因素优化法对多孔聚合物的各步合成工艺条件进行了优化,并得到了较佳的工艺条件:三(1,2,4,5-四甲基-3-溴苯)基硼与1,4-二乙炔苯的摩尔比为1:2.25,反应温度为80℃,反应时间为24h,所得产率为82.9%。溶剂采用三乙胺和四氢呋喃。本文首次使用四三苯基磷钯和碘化亚铜复合催化剂得到较高产率的产物,此课题的研究为此类功能材料的合成提供了有价值的理论依据和实验支持。24465

Synthesis Research of Porous Polymers Based on 1,4-Dibromobenzene
Abstract: Porous organic polymer is a class of new porous material which has high specific area and permanent pore structure. There are varieties of technologies for polymers’ preparation, which make it of great value in the application of gas adsorption, energy storage and heterogeneous catalysisi. Therefore, in recent years the speed of the development of research on porous organic polymer was very fast, becoming a hot spot. The synthesis process conditions of this porous organic polymer were optimized by single factor optimization method and the optimum conditions for the process were as follows: the molar ratio of three (1,2,4,5 - methyl - 3 - bromobenzene) boron and 1, 4-2 acetylene benzene was 1:2.25, the reaction temperature was 80 ℃, the reaction time was 24h, the reaction productivity is 82.9%, reaction solvent was triethylamine and THF. At the same time,the structures of target compounds were characterized by hydrogen nuclear magnetic spectrum.This was the first time for four-triphenylophosphine palladium and cuprous iodide used together as the catalyst and it obtained high yield.The research on this topic for the synthesis of such functional materials
provides valuable theoretical and experimental support.
