title: Ring-in-ring structures from phenanthroline macrocycles with exo- and endotopic binding sites.
abstract: [structure: see text] Three metallosupramolecular ring-in-ring structures are assembled using the HETPHEN concept (in the presence of copper(I)) with macrocyclic phenanthrolines exhibiting exotopic and endotopic coordination sites.
