Constructing cerium supramolecular wheels and encapsulating uranium with a Schiff-base calixpyrrole ligand

Trinuclear, supramolecular wheel structures are formed spontaneously from the metallation of a Schiff-base-pyrrole macrocycle by Ce(3+) cations, while the related actinide U(3+) cation is instead oxidised to U(4+) and encapsulated by the macrocyclic framework.
