Pseudorotaxane Ligand-Induced Formation of Copper(I) Iodide Cluster Based Assembly Materials: From Zero to Three Dimensional

In this work, we have successfully obtained a series of novel ccopper(I)opper(I)-iodideclusters(CuINCs)based assembly materials by coiodide clusters (CuI NCs) based assembly materials by commbining supramolecular bining supramolecular pseudorotaxane ligands{[Mebpe(+)] PF6- @ CB[6]@CB[6] (CB[6]=cucurbit[6]uril(CB[6] = cucurbit[6]uril)), L' center dot PFPF 66}} andlinkersand linkers {{BPHF@CB[6]BPHF@CB[6], [BPHF = C14H20N4(PF6)2], L center dot PF6}, , including discrete cluster CuI1CuI 1 and extended cluster organic frameworks MORF1 and MORF 2. CuI 1 can be described as a dumbbell -shaped molecule with its body -centered site and two vertexes respectively occupied by one [Cu(5)5I(6)](-) cluster and two CB[6] held together by two L'.PF6 ligands.The crystal structures of MORF 1 and MORF2 are1D anionic chain and four-fold interpenetrated 3D cationic diamondoid structure,respectively,which all featured intriguing alternating CB[6] and CuI NCs.structure, respectively, which all featured intriguing alternating CB[6] and CuI NCs. Furthermore, CuI1CuI 1 exhibits outstanding thermochromic and piezochromic luminescence. MORF 1 and MORF2 also are detected pressure dependent luminescence properties with an enormous blue-shift of the near-infrared(NIR)emission band under high pressure compression. These exciting and smart materials possess great potential in the application field of novel temperatureandThese exciting and smart materials possess great potential in the application field of novel temperature and pressure sensors.
