Abstract Luminescent metal-organic frameworks (MOFs) have been extensively investigated as sensors for detection of various compounds. In this work, 5,5',5''-((benzene-1,3,5-tricarbonyl)tris(azanediyl))triisophthalic acid (H6L) and 1,3,5-tri(1H-imidazol-1-yl)benzene (tib) were reacted with Cd(NO3)2·4H2O under solvothermal conditions to generate a MOF [Cd3(H2O)3(L)(tib)2]·5DMA·4H2O (1) (DMA = N,N-dimethylacetamide). Single-crystal X-ray diffraction analysis revealed that 1 is a 2-fold interpenetrated three-dimensional framework composed of Cd-L and Cd-tib two-dimensional networks. Furthermore, its fluorescence and sensing capability towards common organic compounds were explored. The results indicate that 1 could function as a fluorescent probe for nitro-aromatic compounds, especially for 2,4,6-trinitrophenol (TNP) and 4-nitrophenol (4-NP). Graphical Abstract

一种新型的双重互穿 Cd(II) 基金属有机骨架作为硝基芳香化合物的荧光探针

摘要 发光金属有机骨架 (MOF) 作为检测各种化合物的传感器已被广泛研究。在这项工作中，5,5',5''-((benzo-1,3,5-tricarbonyl)tris(azanediyl))triisophthalic acid (H6L) 和 1,3,5-tri(1H-imidazol-1-基)苯 (tib) 在溶剂热条件下与 Cd(NO3)2·4H2O 反应生成 MOF [Cd3(H2O)3(L)(tib)2]·5DMA·4H2O (1) (DMA = N,N -二甲基乙酰胺）。单晶X射线衍射分析表明，1是由Cd-L和Cd-tib二维网络组成的2重互穿三维骨架。此外，探索了其对常见有机化合物的荧光和传感能力。结果表明，1可以作为硝基芳香化合物的荧光探针，尤其是2,4，6-三硝基苯酚 (TNP) 和 4-硝基苯酚 (4-NP)。图形概要
