A metal organic framework, UiO-66-NH, based on a molybdenum Schiff base complex for the efficient electrochemical determination of diphenoxylate.

Diphenoxylate, an agonist and opioid agent, is applied to enhance the activity of the circular muscle of the intestine. In this work, we prepared a novel electrochemical sensor for the determination of diphenoxylate based on a modified UiO-66-NH metal-organic framework (UiO-66-NH MOF) using a molybdenum Schiff base complex and NiS nanoparticles (NiSnp) in a carbon paste electrode (CPE). The UiO-66-NH MOF and UiO-66@Schiff-base-Mo were studied through advanced analysis techniques, such as X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), energy dispersive X-ray analysis (EDAX) and transmission electron microscopy (TEM), to reveal the inherent characteristics of the material.

Influence of synthesis parameters on the optical and photocatalytic properties of solvo/hydrothermal CuS and ZnS nanoparticles.

Copper sulfide and zinc sulfide nanostructures were synthesized using a solvo/hydrothermal method and a thio Schiff base ligand, N-benzylidene ethanethioamide, as a source of sulfide ions. The effects of different synthesis parameters including the type of solvent, temperature, and duration of reactions on the morphology of the CuS and ZnS products were investigated using field emission scanning microscopy and transmission electron microscopy, respectively. The structural aspects of the samples were characterized using powder X-ray diffraction, Fourier transform infrared spectroscopy, and energy dispersive X-ray analysis.

Effect of synthesis method and chemical reagents on the structural parameters, particle size, and optical and photoluminescence properties of ZnS nanostructures.

In this experimental study, ZnS nanostructures were synthesized using two hydrothermal and co-precipitation methods with different precursors. Different reagents and precursors were changed to obtain the best product size and morphology. The structure and crystal phase of the products were studied using X-ray diffraction (XRD) patterns.

Methanol{2-meth-oxy-6-[(2-oxidoprop-yl)imino-meth-yl]phenolato}dioxidomolyb-denum(VI).

In the structure of the title compound, [Mo(C(11)H(13)NO(3))O(2)(CH(3)OH)], the Mo(VI) ion is octahedrally coordinated by two oxide O atoms, the N atom and two deprotonated OH groups of the tridentate Schiff base ligand 2-meth-oxy-6-[(2-oxidoprop-yl)imino-meth-yl]phenolate and by a methanol O atom. In the crystal structure, two complexes are linked via O-H⋯O hydrogen bonds, yielding a centrosymmetric arrangement involving the methanol hydr-oxy group and one of the ligand O atoms coordinated to the Mo(VI) ion.
