Covalent macrocycles and three-dimensional cages were prepared by the self-assembly of di- or tri-topic ani- lines and 2,6-diformylpyridine subcomponents around palladium(II) templates. The resulting 2,6-bis(imino)pyridyl-PdII motif contains a tridentate ligand leaving a free coordination site on the PdII centers, which points inward. The binding of ligands to the free coordination sites in these assemblies was found to alter the product stability, and multi-topic ligands could be used to control product size. Multi-topic ligands also bridged metallomacrocycles to form higher-order supramo- lecular assemblies, which were characterized via NMR spectroscopy, mass spectrometry and X-ray crystallography. An ef- ficient method was developed to reduce the imine bonds to and cages, which were inaccessible through other means.
