Inclusion complex formation of 3-octyl-1-methylimidazolium bromide (OMImBr) into α- and β-cyclodextrins has been investigated with physicochemical methods and spectroscopic techniques. Spectroscopic studies like FT-IR, UV and Visible and ¹H NMR, 2D ROESY NMR were carried out to confirm the formation of inclusion complexes. The surface tension and conductivity measurements reveal the 1:1 stoichiometry of the inclusion complex. The well-known Job’s method and Benesi–Hildebrand method from UV study was also applied for confirmation the host-guest stoichiometry.
