Zhang, Ya-Wen;Bai, Sha;Wang, Yao-Yu;Han, Ying-Feng research published 《 A Strategy for the Construction of Triply Interlocked Organometallic Cages by Rational Design of Poly-NHC Precursors》, the research content is summarized as follows. Three-dimensional (3D) triply interlocked catenanes are a family of chem. topologies that consist of two identical, mech. interlocked coordination cage components with intriguingly complex structures. Although only a few successful constructions of 3-dimensional interlocked catenanes were achieved to date via metal-mediated assembly, these complex structures have thus far only been targeted by metal-N/O coordination techniques. Here, taking advantage of rational ligand design, the authors report the efficient construction of 3-dimensional triply interlocked [2]catenanes [Ag3L2]2, wherein the metal ions exclusively form bonds to N-heterocyclic carbene (NHC) units, and their subsequent transmetalation to the corresponding [Au3L2]2 Au analogs. The formation and transmetalation reactions proceed under mild conditions and are generally applicable. Characterization techniques were applied to confirm the formation and structure of the desired 3-dimensional triply interlocked architectures: multinuclear NMR spectroscopy, ESI-MS, and single-crystal x-ray diffraction anal. The solid-state structure of [Ag3(1a)2]2(PF6)6 unambiguously confirms the existence of a 3-dimensional catenane that consists of two identical, mech. interlocked trinuclear hexacarbene cage components. The interlocking of two 3-dimensional cages into a [2]catenane is driven by the efficient π···π stacking of triazine-triazine stacks with cooperative interactions between imidazo[1,5-a]pyridine subunits. Notably, the triply interlocked organometallic cages exhibit good stability toward various organic solvents, concentrations, and temperatures, and no disassembly occurred in the presence of coronene or pyrene. The future construction of mech. interlocked architectures using metal-carbene bonds rather than metal-N bonds may provide assemblies with interesting properties for as-yet-unimagined applications in fields such as sensors and mol. elec. conductors.
