Structure and photochromic properties of two metal-viologen complexes derived from 1-amyl-4,4′-bipyridinium ligand
In this work, two metal-viologen complexes, formulated as [Zn2(AQ)2(BTEC)(H2O)8](H2BTEC)·6H2O (1) and {[Cu(AQ)(HBTEC)(H2O)]·(H4BTEC)0.5}n (2), have been designed and prepared in the reaction of the mono-substituted viologen ligand 1-amyl-4,4′-bipyridinium bromide (AQBr), 1,2,4,5-benzenetetracarboxylic acid (H4BTEC) and different metal ions. Single-crystal structure analysis reveals that compound 1 has a discrete structure and compound 2 has a layered structure. In general, incorporating the viologen ligand into the framework will result in expected photochromic behavior. However, only compound 1 exhibits obvious photochromic behavior, compound 2 is non-photochromic. In addition, compound 1 also exhibits photo-modulated luminescence properties in the solid state and can be deposited on the filter paper, showing potential applications as an inkless printing material.
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.
