Abstract
Two imidazolium-based hexafluorophosphate ionic liquids (ILs), 1-butyl-3-methylimidazolium hexafluorophosphate and 1-dodecyl-3-methylimidazolium hexafluorophosphate, were used to form inclusion complexes (ICs) with α- and β-cyclodextrins (CDs). Formation of the ICs of each CD with each IL was confirmed by the appearance of a characteristic peak in the UV region. Characterisation of the ICs by NMR and FT-IR spectroscopy provided information about the interactions between the host and guest molecules and the structure of the ICs. Temperature-dependent particle size analysis by dynamic light scattering suggested that the size of the host and the guest governs their stability.
