Flexible porphyrin covalent cages behave as allosteric receptors and control guest encapsulation through large conformational changes. In the closed state, the cage cavity is restricted preventing guest molecules to be captured. Coordination of silver ions to the allosteric sites switches the cage to an open state allowing for the encapsulation of guest molecules. For more details, see the Full Paper by K. Rissanen, V. Heitz and co‐workers on page 1481 ff.
