title: Anion binding motifs: topicity and charge in amidocryptands.
abstract: An expanded amidocryptand with propyl linkages provides multitopic sites for binding anions and water molecules. Upon quaternization of the two bridgehead amines, the molecular shape changes from an inverted Y to that of a bowl, which is filled with water and topped by the anion.
