摘要
在溶剂热条件下，以4-亚砜- n -（4-羧基苯基）萘-1,8-二氧亚胺（HSCND）和Cu(NO3)2为原料合成了铜配位聚合物{[Cu3(SCND)2(OH)2(H2O)4]·4H2O}n （CP-1）。通过元素分析（EA）、单晶x射线衍射（SXRD）、傅里叶变换红外光谱（FT-IR）、热重分析（TGA）、粉末x射线衍射（PXRD）等手段对其结构进行了表征。单晶x射线分析表明，CP-1具有独特的1D [CuOCu]∞链状结构。Hirshfeld分析表明，这些链可以通过OH··O和CH··O氢键相互作用，形成三维超分子结构。发光传感研究表明，CP-1可以灵敏地检测低浓度的Al3+、MnO4−、Cr2O72−和对硝基苯胺（p-NA），并阐明了其传感机制。CP-1可以作为荧光探针，为直接检测水溶液中有害物质提供了新的策略。
A multifunctional copper-based coordination polymer for the detection of Al3+, MnO4−, Cr2O72- and p-NA in aqueous media
Under solvothermal conditions, a copper coordination polymer {[Cu3(SCND)2(OH)2(H2O)4]·4H2O}n (CP-1) was synthesized using 4-sulfo-N-(4-carboxyphenyl)naphthalene-1,8-dicarboximide (HSCND) and Cu(NO3)2. The structure was characterized by elemental analysis (EA), single-crystal X-ray diffraction (SXRD), fourier transform infrared spectroscopy (FT-IR), thermogravimetric analysis (TGA), powder X-ray diffraction (PXRD), etc. Single-crystal X-ray analysis revealed that CP-1 exhibits a unique 1D [CuOCu]∞ chain-like structure. Hirshfeld analysis shows that the chains can interact with each other through OH···O and CH···O hydrogen bonds to form a 3D supramolecular structure. Luminescent sensing studies have shown that CP-1 can sensitively detect lower concentrations of Al3+, MnO4−, Cr2O72−, and p-nitroaniline (p-NA) and elucidate the sensing mechanism. CP-1 can serve as a fluorescent probe, providing a new strategy for directly detecting harmful substances in aqueous solutions.
期刊介绍：
The Journal of Molecular Structure is dedicated to the publication of full-length articles and review papers, providing important new structural information on all types of chemical species including:
• Stable and unstable molecules in all types of environments (vapour, molecular beam, liquid, solution, liquid crystal, solid state, matrix-isolated, surface-absorbed etc.)
• Chemical intermediates
• Molecules in excited states
• Biological molecules
• Polymers.
The methods used may include any combination of spectroscopic and non-spectroscopic techniques, for example:
• Infrared spectroscopy (mid, far, near)
• Raman spectroscopy and non-linear Raman methods (CARS, etc.)
• Electronic absorption spectroscopy
• Optical rotatory dispersion and circular dichroism
• Fluorescence and phosphorescence techniques
• Electron spectroscopies (PES, XPS), EXAFS, etc.
• Microwave spectroscopy
• Electron diffraction
• NMR and ESR spectroscopies
• Mössbauer spectroscopy
• X-ray crystallography
• Charge Density Analyses
• Computational Studies (supplementing experimental methods)
We encourage publications combining theoretical and experimental approaches. The structural insights gained by the studies should be correlated with the properties, activity and/ or reactivity of the molecule under investigation and the relevance of this molecule and its implications should be discussed.
