A comprehensive molecular insight into host-guest interaction of Phenanthrene with native and ionic liquid modified beta-cyclodextrins: Preparation and characterization in aqueous medium and solid state

The inclusion complexes of Phenanthrene with native beta CD and ionic liquid modified beta CD were prepared and investigated in both solid and solution states. The formation of the inclusion complexes were successfully monitored by FTIR, TGA, DSC, 1D H-1 NMR, 2D NOESY NMR and UV-vis spectroscopy. Th...
