Enhanced removal of organic dyes from aqueous solutions by new magnetic HKUST-1: facile strategy for synthesis.

A novel, magnetic HKUST-1 MOF based on MgFeO-NH was designed and synthesized in two steps and applied effective removal of malachite green (MG), crystal violet (CV), and methylene blue (MB) from water samples. Characterization of the newly synthesized MgFeO-NH-HKUST-1 was performed by various techniques such as Fourier transform infrared spectroscopy, X-ray diffraction, Field emission scanning electron microscopy, Brunauer-Emmett-Teller, Thermal gravimetric analysis, and Vibration sampling magnetometry. Malachite green, crystal violet and methylene blue are toxic and mutagenic dyes that can be released into the water in different ways and cause many problems for human health and the environment.

Ln Based Metal-organic Framework for Fluorescence "Turn Off-On" Sensing of Hg.

A highly luminescent Ln-MOF [La(NDC)(DMF)(HO)], (NDC = 2, 6 naphthalen dicarboxylic acid) was designed and synthesized. The structure was characterized by x-ray single structure determination, TGA, IR spectra and PXRD and fluorescence spectroscopy. The structure shows high fluorescence intensity based on the presence of lanthanide metal and ligand.

HKUST-1 metal-organic framework for dispersive solid phase extraction of 2-methyl-4-chlorophenoxyacetic acid (MCPA) prior to its determination by ion mobility spectrometry.

The authors describe a method for the extraction of the herbicide 2-methyl-4-chlorophenoxyacetic acid (MCPA) from agricultural products. The metal organic framework (MOF) HKUST-1 (a copper(II) benzene-1,3,5-tricarboxylate) was used as a sorbent for efficient clean-up and preconcentration of MCPA. The effects of pH value, stirring time, amount of sorbent on extraction were optimized by central composite design.

Sonochemical synthesis and characterization of a new nano Ce(III) coordination supramolecular compound; highly sensitive direct fluorescent sensor for Cu.

Micro and nano-structures of a new Ce(III) Coordination supramolecular compound, [Ce (1,5-NDS)(HO)],1, (1,5-Naphthalenedisulfonic acid), were prepared using hydrothermal and sonochemical approaches, respectively. These new micro and nano structures were characterized by elemental analysis, IR spectra, thermal gravimetric analysis (TGA), scanning electron microscopy (SEM), and powder X-ray diffraction. The X-ray single crystal structure determination of 1 shows that it features a neutral 2D framework based on the [CeHOS] clusters as a secondary building unit (SBU) which shows a sql/Shubnikov tetragonal plane net.

Potassium ion-mediated non-covalent bonded coordination polymers.

Crystal structures and vibrational spectra of three related network-forming coordination complexes have been studied. Two novel thermodynamically stable pseudo-polymorphic solvated rhodium chloro compounds, [cis-RhCl(4)(DMSO-κS)(2)K](n), 1, and [cis-RhCl(4)(DMSO-κS)(2)K·3H(2)O](n), 2, and one metastable compound [trans-RhCl(4)(DMSO-κS)(2)K·0.25H(2)O](n), 3, crystallize at ambient temperature in the orthorhombic space group P2(1)2(1)2(1) for 1, and the monoclinic space groups P2(1)/n and P2(1)/c for 2 and 3, respectively.
