研究了具有氟化通道的类沸石金属有机骨架 (MOF) Zn(hfipbb) 的稳定性和碳氢化合物/碳氟化合物吸附性能。通过热重分析 (TGA) 和粉末 X 射线衍射 (PXRD) 测量的结合,我们证实 Zn(hfipbb) 具有极高的水热稳定性和热稳定性。 Zn(hfipbb)对水和甲醇的吸附行为表明其具有高疏水性,但对醇类具有高吸附性。己烷和全氟己烷吸附测量表明,Zn(hfipbb)中的氟化通道与碳氢化合物和碳氟化合物具有高亲和力。通道的高亲氟性质和化合物的高稳定性表明其在实际分离应用中的潜在用途。
The stabilities and hydrocarbon/fluorocarbon sorption properties of a zeolite-like metal-organic framework (MOF) Zn(hfipbb) with fluorinated channels has been studied. By the combination of thermogravimetric analysis (TGA) and powder X-ray diffraction (PXRD) measurements, we confirm that Zn(hfipbb) has exceptionally high hydrothermal and thermal stabilities. The adsorption behaviors of water and methanol by Zn(hfipbb) indicate that it is highly hydrophobic but with high adsorption of alcohols. Hexane and perfluorohexane adsorption measurements show that the fluorinated channels in Zn(hfipbb) have high affinity with hydrocarbon and fluorocarbon. The high fluorophilic nature of the channels and the high stability of the compound suggest its potential utility in practical separation applications.
