Supramolecular assembly of ionic liquid with cyclic oligosaccharide in aqueous environments

A suitable host-guest inclusion complex has beenmade with a guest molecule, 1-methyl-3- octylimidazolium chloride ([MOIm]Cl) and a host molecule, α-cyclodextrin in aqueous medium. Formation of the host-guest inclusion complex has been established by Surface tension and conductivity readings while1H NMR and ultraviolet spectroscopy readingconfirms1:1 host-guest stoichiometry. These results have implications for the formation of host-guest inclusion complex of studied ionic liquid as guest in aqueous α–cyclodextrin media.
