Cover Feature: Supramolecular Coordination Cages Based on N‐Heterocyclic Carbene‐Gold(I) Ligands and Their Precursors: Self‐Assembly, Structural Transformation and Guest‐Binding Properties (Chem. Eur. J. 29/2021)

Systematic design and self-assembly of complex supramolecular coordination cages with predictable configurations has been a long-standing challenge in chemistry, which is as mysterious as the starry sky depicted in the cover image. This work reports a trackable CpZr-involved cage to cage conversion to generate a heteroleptic V2E3 cage from two homoleptic cages with different geometries of V2E3 and V4E6. Moreover, SCC-2 cage possesses a cationic cavity allowing the encapsulation of a series of sulfonate anionic guests. More information can be found in the Full Paper by S. Bai, Y.-F. Han, et al.
