The supramolecular structure of the inclusion complex of β-cyclodextrin (β-CD) with 1,1',2,2'-tetramethyl-3,3'-(p-phenylenedimethylene) diimidazolium dibromide (TetraPhimBr), a dicationic ionic liquid, has been investigated. The inclusion complex with 1:1 molar ratio was prepared by a kneading method. Fourier transform infrared spectroscopy (FTIR), powder X-ray diffraction (XRD) analysis, (1)H NMR and thermogravimetric analysis (TGA) confirmed the formation of the inclusion complex. The results showed that the host-guest system is a fine crystalline powder. The decomposition temperature of the inclusion complex is lower than that of its parent molecules, TetraPhimBr and β-CD individually.
本文研究了β-环糊精（β-CD）与 1,1',2,2'-四甲基-3,3'-(对亚苯基二亚甲基)二咪唑溴化二阳离子（TetraPhimBr），一种双离子液体，的包络复合物的超分子结构。通过捏合法制备了摩尔比为 1:1 的包络复合物。傅里叶变换红外光谱（FTIR）、粉末 X 射线衍射（XRD）分析、（1）H NMR 和热重分析（TGA）证实了包络复合物的形成。结果表明，主体-客体体系是一种精细的结晶粉末。包络复合物的分解温度低于其母体分子 TetraPhimBr 和 β-CD 各自的分解温度。
