ABSTRACT
The amalgamation of different components into a giant and intricate structure that makes quantitative spontaneous assembly through molecular design is indispensable but challenging. To construct novel metallo-supramolecular architectures, here we present an architectural principle based on multicomponent self-assembly. Using carefully designed hexatopic terpyridine-based metallo-organic ligand (MOL), [Ru2T2K], report the formation supramolecular trapezoid Zn5[Ru2T2K]V2, hollow hexagon Zn15[Ru2T2K]3K3, star-shaped supramolecule Zn18[Ru2T2K]3[Ru2X2V]3, all which were assembled by one-pot, nearly [Ru2T2K] with ditopic 60°-directed bisterpyridine V, tetrakisterpyridine K, MOL [Ru2X2V], respectively. complementary ligands selected basis size- shape-fit principles, actually similar to mortise–tenon joint aligns locks two wood components. This strategy expected open door sophisticated designer supramolecules nonbiological materials. multivalent connections within mutual give rise stable assemblies, are unambiguously characterized NMR, ESI-MS, TWIM-MS, TEM analyses.
