A macrocyclic supramolecular complex obtained from a fullerene ligand bearing two pyridine substituents and a bis-Zn(II)-porphyrin receptor

A fullerene derivative bearing two pyridine subunits has been designed to allow assembly with a bis-Zn(II)-phorphyrin receptor with two equivalent Zn binding sites separated by about 20 A. Owing to the complementarity between the bis-Zn(II)-porphyrin receptor and a fullerene ligand bearing two pyridine substituents, the substrate can be clicked on the ditopic receptor, thus leading to a stable non-covalent macrocyclic 1:1 complex.
