Structural distinction and highly sensitive fluorescent detection properties of Cd-based multifunctional sensors with three flexible isomers
Many environmental pollutants are found and need to be detected and treated with the rapid development of industry. Three novel Cd (II) coordination polymers (Cd-CPs) (1–3), with the formula of [Cd(2-HDBB)(4,4′-bbpy)](1), [Cd(3-HDBB)(4,4′-bbpy)](2) and [Cd(4-HDBB)(4,4′-bbpy)0.5·2H2O](3) based on three soft organic isomers: n-(3,5-dicarboxylato benzyloxy) benzoic acid (n = 2, 3 or 4-H3DBB), with one linear N-donor ligand 4,4′-bis(imidazolyl) biphenyl (4,4′-bbpy) have been synthesized hydrothermally and characterized in detail. The significant structural differences are both coordination polymers 1 and 2 featuring two-dimensional networks, while 3 with 1D ladder-like chain due to the change of isomers. Despite structural differences, the series of Cd-CPs exhibits similar fluorescence sensing properties. Fluorescent sensing properties exhibit all the Cd-CPs have been discovered to detect Fe3+, Cr2O72−, tetracycline (TET) and nitrobenzene (NB) selectively and sensitively with the low detection limits, respectively. The results of theoretical calculation verified the fluorescence detection mechanism of NB by these cadmium complexes. Therefore, the Cd-CPs might be used as an excellent multi-functional luminescent sensor in the future.
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.
