Self-assembling molecular capsules based on noncovalent interactions have attracted considerable interest due to their potential as molecular storage, sensor, catalysts, or reaction chambers in the field of supramolecular chemistry. Cavitand having four amidobenzyl moieties on the upper rim of imino-cavitand formed stable molecular capsules in nonpolar solvents by the eight intermolecular amide N-H···O=C hydrogen bondings. The synthesis and characteristics of this amide molecular capsule toward various guests will be presented.
