Cover Feature: Confinement Effects of Coordination Cages on the Synthesis and Application of Polyoxometalates (Chem. Eur. J. 7/2025)

The confinement effects within coordination cages unlock new possibilities for stabilizing and tuning polyoxometalates (POMs). The cover uses the metaphor of birds in a cage to illustrate these effects, with the background emphasizing the structural interplay between POMs and coordination cages. This synergy also paves the way for innovative applications in catalysis, energy storage, electronics, and magnetics, exemplifying the elegance of supramolecular design.
