Summary:Cobalt( iii ) tetrahedral capsules have been prepared using an assembly-followed-by-oxidation protocol from a cobalt( ii ) precursor and a readily derivatizable pyridyl-triazole ligand system. Experiments designed to probe the constitutional dynamics show that these architectures are in a non-equilibrium state. A preliminary investigation into the host-guest chemistry of a water-soluble derivative shows it can bind and differentiate a range of different neutral organic molecules. The stability of this ensemble also permits the study of guest-binding at high salt concentrations. Constitutionally non-dynamic cobalt( iii ) tetrahedral capsules have been prepared using an assembly-followed-by-oxidation protocol.
