D. Krois et Uh. Brinker, INDUCED CIRCULAR-DICHROISM AND UV-VIS ABSORPTION-SPECTROSCOPY OF CYCLODEXTRIN INCLUSION COMPLEXES - STRUCTURAL ELUCIDATION OF SUPRAMOLECULAR AZI-ADAMANTANE (SPIRO[ADAMANTANE-2,3'-DIAZIRINE]), Journal of the American Chemical Society, 120(45), 1998, pp. 11627-11632
The first induced circular dichroism (ICD) analyses of diazirine@cyclo
dextrin inclusion complexes are reported. The stoichiometries and asso
ciation constants of the guest@host complexes with alpha-, beta-, and
gamma-cyclodextrin were determined. In;addition, with the cl-cyclodext
rin complex, UV-vis spectroscopy of water-ethanol solutions showed rem
arkable fine structure, probably indicating that the diazirine experie
nces a:nonpolar microenvironment. These analytical methods provide det
ails about the architecture and nature of these supramolecular carbene
precursors.
