Abstract
Lithium(I)-based compounds are extensively utilized across various domains, however, their structural characteristics remain inadequately explored, which has hindered further development and application of their functionalities. Thus, the exploration of their structural intricacies is crucial for unlocking their full potential and paving the way for innovative applications in diverse fields. In this study, four Li(I)-based metal organic frameworks (MOFs), namely, [Li4(BNZ)4(H2O)4]n (1), [Li(HBNZ)]n (2), [Li(BNZ)(DPRO)]n (3), [Li2(MBNZ)2(DPRO)2]n (4), are synthesized through hydrothermal method, and structurally characterized by single crystal X-ray diffraction, powder X-ray diffraction, and IR, where BNZ, HBNZ, MBNZ and DPRO are benzoic acid, 4-hydroxybenzoic acid, 3-methoxybenzoic acid and d-proline, respectively. Crystallographic analysis reveals that all these complexes are two-dimensional layered architectures, of which 3 and 4 display a similar wave-like square grids network. The crystal structures of the complexes 1–4 are stabilized by one or more kinds of NH···O, CH···O, OH···O, CH···π, π-π interactions, and the intermolecular interactions and thermal stabilities of these complexes were also analyzed by Hirshfeld surface and thermogravimetric analysis, respectively. Moreover, these complexes show the great photoluminescence properties and antibacterial activities, exhibiting remarkable potential applications in both material and pharmaceutical science, and the necessity for continued research to promise a paradigm shift in the design and application of advanced materials.
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.
