Cover Feature: Stimuli Induced Reversible Switching Between a Self‐Assembled 2‐Catenane and the Constituent Coordination Rings (Chem. Eur. J. 7/2025)

A magician entertains spectators by linking a pair of metal rings followed by unlinking those using mechanical tricks. The cover artwork illustrates the linking and unlinking of a pair of self-assembled dynamic coordination rings (molecular magic rings). The rings are interlocked when taken in water and separated by applying a chemical trick in the form of stimulus-I, which is a guest molecule suitable for occupying the inner-space of the rings. Such a guest can be sequestered by stimulus-II, which is a more powerful host. More information about the tricks can be found in the Research Article by D. K. Chand and co-workers (DOI: 10.1002/chem.202403837).
