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

Chem Commun (Camb). 2010 Mar 21;46(11):1833-5. doi: 10.1039/b921132b. Epub 2010 Feb 12.

Abstract

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.
