title: Recognition of guests by water-stabilized cavitand hosts.
abstract: Water stabilized, deep cavitands with three walls and an open side are shown to be receptors for amines and ammonium cations bearing bulky aliphatic groups. The missing wall allows the binding of guests not accommodated by the four-walled counterparts.
