title: Complexation of triptycene-based cylindrical macrotricyclic polyether toward diquaternary salts: ion-controlled binding and release of the guests.
abstract: Triptycene-based cylindrical macrotricyclic polyether 1 has been proved to be an efficient host for the complexation with diquaternary salts in solution and in the solid state. Moreover, it was also found that binding and release of the guest molecules could be easily controlled by the addition and removal of potassium ions.
