摘要：

Monomethyl ether of monodeoxycalix[4]arene (2) is found to be a good receptor of small neutral organic guest molecules in carbon tetrachloride solution. The host has an open-ended narrow necked cone shape so that the solvent inaccessible cavity facilitates the inclusion of the guests. Since the guest with highly acidic C-H bonds binds strongly in the cavity, the C-H acidity of the guests rather than van der Waals interaction plays a dominant role in the stability of the complexes.
