A 3D Luminescent Metal‐organic Framework Constructed from Cu4I4 Cubane Clusters and Triangular Imidazole Ligand

Abstract. The solvothermal reaction between cuprous iodide and the rigid triangular imidazole ligand in mixed N,N′-dimethylacetamide (DMA)-acetonitrile solvent leads to the isolation of the 3D metal-organic framework [(Cu4I4)3(TIPA)4]·7DMA (1) [TIPA = tri(4-imidazolylphenyl) amine], which was characterized by elemental analysis, IR spectroscopy, powder X-ray diffraction, and single-crystal X-ray diffraction. Topologically, the structure of 1 is an unprecedented 3,3,4,4-connected net with a point symbol of {4.8.10}2{4.82}2{42.82.102}2{84.122}. Compound 1 exhibits orange-red photoluminescence with an emission maximum at 622 nm at room temperature.
