摘要: Host-guest interaction of ionic liquid (IL) 1-decyl-3-methylimidazolium tetrafluoroborate [Dmim][BF4] within α-cyclodextrin (α-CD) has been studied by different spectroscopic techniques and our investigated system is significant in the field supramolecular chemistry medicine. Benesi-Hildebrand correlation used to study stoichiometry host-guest complexation. Here concurrence with FT-IR dynamic light scattering (DLS) results, it shown that α-CD interacts [Dmim][BF4], induces compositional structural changes. Characterization [Dmim][BF4]-α-CD inclusion complex (IC) 1H NMR spectroscopy provided information about complexation among molecules structure ICs. results confirm formation while UV-vis spectroscopy, DLS FTIR studies show development IC 1:1 stoichiometry. The present can be highly applicable fields pharmaceutical science, supra-molecular material science.
