HOST-GUEST INCLUSION COMPLEXATION BETWEEN Β-CYCLODEXTRIN AND SOME CHROMENONES: 2D ROESY INVESTIGATION

摘要: Cyclodextrin can act as a host and form Host: Guest inclusion complexes with chromenones. The spectroscopic response, crystallite size, and the structural orientation of β-cyclodextrin-Chromenones inclusion complex are resolved by fluorescence, X-ray diffractometry, and nuclear magnetic resonance spectroscopy. The bond length and width of the chromenones for their encapsulation towards β-cyclodextrin are checked by Rasmol 2.7. 5.2. Concrete evidences of the Host: Guest inclusion complexes formed between β-cyclodextrin and chromenones are acquired from Two dimensional rotating-frame nuclear over-hauser effect correlation spectroscopy and the supported structures are reported.
