Supramolecular triangular orthobicupola: Self-assembly of a giant Johnson solid J27

Twisted rectangular subunits self-assemble into a ferritin-like capsule

“…24 As with natural protein cages, the symmetry elements of the overall structure do not emerge from the individual subunits, which are in low local-symmetry configurations, but rather from how they come together. 2,26,27 Unlike other large metal-organic capsules, [9][10][11][12][13][14]19,28 Here, we report the assembly of a large metal-organic capsule from simple subcomponents. Instead of single ligands spanning its vertices, each face of the tetrahedral capsule is paneled by three ligands, thus leading to a much larger framework than would otherwise be observed.…”

Supramolecular cuboctahedra with aggregation-induced emission enhancement and external binding ability

“…Using terpyridine monomers coordinated with transition metal ions [ i.e. , <tpy-M 2+ -tpy> (M = transition metal ion)] as linking units 36 and inspired by Archimedean solids, a series of Archimedean-shaped supramolecular cages, such as tetrahedra, 37–39 octahedra, 40,41 and cuboctahedra, 42 were reported. Based on a similar design principle, we report two cuboctahedral-shaped supramolecular cages S1 and S2 .…”

Metal ion determined self-assembly using terpyridine building blocks

“…2,2′:6′,2′′-Terpyridines are widely used as tridentate ligands due to their ability to coordinate with various transition metals, 22,23 and the binding ability with different metal ions increases in the order of Mn < Cu < Cd < Zn < Co. 24 This unique characteristic supports the primacy of the terpyridyl ligand in enhancing the complexity of complexes. Inspired by this fact, it was aimed to investigate the influence of using metals with different binding capacities on the structure of metal–organic supramolecular cages.…”
