【摘要】 近几年,一些MOFs可用于液相吸附分离有机物,特别是有机小分子,但这些报道大都在单一溶液中进行,而且也仅仅关注于其选择性,而对于多种溶液混合后的研究报道却很少,还有很多问题没有解决[1]。利用MOFs材料分离纯化有机分子,尤其是有机大分子还有很大潜力[2]。通过溶剂热法合成了一个BioMOF,它对有机染料能选择性吸附和释放。主客体之间的电荷效应,孔洞尺寸的大小,以及主客体之间的相互作用是影响其吸附分离的主要因素。其中,BioMOF和染料分子之间的静电作用在选择性方面起主导作用,主客体间的氢键作用显著影响其吸附的能力和速率。因此这种金属有机框架有望成为液相色谱柱的固定相。更多还原

【Abstract】 In recent years,liquid-phase selective adsorption and separation of organic compounds,especially small organic molecules,have been tested on MOFs.Most of the reports only focus on the selective adsorption,but not the separation of mixed solution.There are still many problems unsolved.In fact,porous MOFs materials have great potentialities for adsorption and separation of organic molecules,particularly large organic compounds.We have synthesized a biological metal-organic framework by solvothermal method and demonstrated its selective adsorption organic dyes properties.Charge effect,size effect and interaction of host-guest are the most important factors for adsorption separation.They may serve as the basis for applications in liquid column-chromatographic.更多还原
