Host-guest inclusion complex of an ionic solid (tetrabutyl ammonium iodide) with α- and β- cyclodextrin has been explored by various physicochemical and spectroscopic methods. Surface tension and conductivity studies indicated 1:1 stoichiometry of the inclusion complexes and ¹H NMR and FT-IR studies substantiated the inclusion phenomenon. Density, viscosity and refractive index studies characterized the interactions of cyclodextrin with tetrabutyl ammonium iodide, which also indicated greater extent of encapsulation in β-cyclodextrin than in α-cyclodextrin. Hydrophobic effect, structural effect, electrostatic force and H-bonding interactions were mainly exploited to explicate the formation of inclusion complex.
