Dual-mode recognition of oxalate by protonated azacryptate hosts; conformational response of the guest maximizes pi-stacking interactions.
Exceptionally large complexation constants for oxalate encapsulated within azacryptand hosts are partly explained by pi-stacking interactions between C=O and aromatic rings.
