Abstract 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, 1H 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. View Full-Text
