Abstract

The conformations and properties of benzimidazole cavitand with four benzimidazole flaps are studied by (super 1)H NMR. The benzimidazole cavitand could form very stable vase structures with an enforced concave cavity by intermolecular hydrogen bonding with four hydroxyl-containing molecules, X-OH, such as methanol, acetic acid, and trifluoroacetic acid.
