Single‐crystal to single‐crystal transformations are possible by ion‐exchange and transport reactions through supramolecular channels that are composed of crown ether molecules and use trihalide ions as scaffolds. Kinetic measurements of ion transport at different temperatures provide activation energy data and show that a very fast exchange of K + ions with Na + ions occurs.
