摘要 | Metal-free and metal-containing molecular trefoil knots are fascinating ensembles that are usually covalently assembled, the latter requiring the rational design of di- or multidentate/multipodal ligands as connectors. In this work, we describe the self-assembly of pentadecanuclear Au-I trefoil knots [Au-15(C equivalent to CR)(15)] from monoalkynes HC equivalent to CR (R=9,9-X-2-fluorenyl with X=nBu, n-hexyl) and [Au-I(THT)Cl]. Hetero-bimetallic counterparts [Au9M6(C equivalent to CR)(15)] (M=Cu/Ag) were self-assembled by reactions of [Au-15(C equivalent to CR)(15)] with [Cu(MeCN)(4)](+)/AgNO3 and HC equivalent to CR. The type of pentadecanuclear trefoil knots described herein is characterized by X-ray crystallography, 2D NMR and HR-ESI-MS. [Au9Cu6(C equivalent to CR)(15)] is relatively stable in hexane; its excited state properties were investigated. DFT calculations revealed that non-covalent metal-metal and metal-ligand interactions, together with longer alkyl chain-strengthened inter-ligand dispersion interactions, govern the stability of the trefoil knot structures. |
