- Abstract
- Resorcin[4]arene-based tetrakis(N-hydantolnylamido)cavitand 1 forms a stable molecular capsule in the presence of suitable anionic guests such as CH3OSO3- or BF4- in C2D2Cl4. Molecular capsule G(2)@1(2) is stabilized by the eight intermolecular hide N-H center dot center dot center dot O=C hydrogen bondings, two from each four paired hydantoinyl units, and the eight intramolecular amide N-H center dot center dot center dot OCH2-O hydrogen bondings, four on each two cavitands. The formations of molecular capsules were confirmed by H-1, 2D NOESY, and 2D-DOSY NMR.
