Abstract

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.
