Coordination polymer networks with s-block metal ions

Alkali and alkaline earth metal cations form the s-block elements of the periodic table where they belong to the groups 1 and 2, respectively. They play an important role in nature, for instance alkali cations Li+, Na+ and K+ have very specific functions such as the regulation of the ionic equilibrium of living cells in our body. Alkaline earth cations also have a contribution in our body, for instance calcium is the most important constituent of our organism. They above all, and always, find applications in man-made materials in a wide range of fields: catalysts, ferroelectrics, metallic conductors and superconductor materials. They are known for their mainly ionic chemistry in aqueous medium, and a varying coordination number, depending on the size of the binding partners as well as on electrostatic interactions between the ligands and the metal ions. This makes the strategic synthesis of coordination polymer networks with these metal ions a challenge and explains why few systematic results in the generation of metal-organic frameworks (MOFs) are found in the literature. This review highlights the recent results in the field, bringing together the systematic approaches with results obtained by serendipity, to give an overview on current and future possibilities.

Crystal structure, Hirshfeld surface analysis and photocatalytic activities of a cobalt(III) complex based on acid and alkaline mixed ligands

A novel Co(III) complex [Co(chda)(nta)] (1) (chda = trans-(1R,2R)-1,2-cyclohexanediamine, H3nta = nitrilotriacetic acid) was synthesized based on chda and H3nta ligands at room temperature. Complex 1 was structurally identified by single-crystal X-ray diffraction, elemental analysis, FT-IR and Raman spectrum. Complex 1 was connected by the intermolecular N?H¡¤¡¤¡¤O hydrogen bonds to form a 2D supramolecular structure. The 3D Hirshfeld surface and 2D fingerprint plots were used to further study the intermolecular interactions of complex 1. The intermolecular O¡¤¡¤¡¤H and H¡¤¡¤¡¤H contacts were the most significant interactions in the crystal, which comprised 96.6% of the total Hirshfeld surface. In addition, complex 1 exhibited excellent photocatalytic activity for the removal of methylene blue under UV light. The possible photocatalytic mechanism and reaction kinetics were also discussed.

Structure and DNA cleavage properties of two copper(ii) complexes of the pyridine-pyrazole-containing ligands mbpzbpy and Hmpzbpya

The DNA-cleavage properties of the two copper(ii) complexes, [Cu(mbpzbpy)Br2](H2O)2.5 (1) and [Cu(mpzbpya)Cl](CH3OH) (2), obtained from the ligands 6,6?-bis(3,5-dimethyl-N-pyrazolmethyl)-2,2?-bipyridine) (mbpzbpy) and 6?-(3,5-dimethyl-N-pyrazolmethyl)-2,2?-bipyridine-6-carboxylic acid) (Hmpzbpya), respectively, are reported. Upon coordination to Cu II chloride in methanol, one arm of the ligand mbpzbpy is hydrolyzed to form mpzbpya. Under the same experimental conditions, the reaction of mbpzbpy with CuBr2 does not lead to ligand hydrolysis. The ligand mpzbpya is coordinated to a copper(ii) ion generating a CuN3OCl chromophore, resulting in a distorted square-pyramidal environment, whereas with the N 4 mbpzbpy ligand, the CuII ion is four-coordinated in a distorted square planar geometry. Both complexes promote the oxidative DNA cleavage of X174 phage DNA in the absence of reductant. The oxidative nature of the DNA cleavage reaction has been confirmed by religation and cell-transformation experiments. Studies using standard radical scavengers suggest the involvement of hydroxyl radicals in the oxidative cleavage of DNA. Although both compounds do convert form I (supercoiled) DNA to form II (nicked, relaxed form), only complex 1 is able to produce small amounts of form III (linearized DNA). This observation may be explained either by the attack of the copper(ii) complexes to only one single strand of DNA, or by a single cleavage event. Statistical analysis of relative DNA quantities present after the treatment with both copper(ii) complexes supports a random mode of DNA cleavage. This journal is The Royal Society of Chemistry.

Fabrication of a molecularly imprinted polymer immobilized membrane with nanopores and its application in determination of beta2-agonists in pork samples

In this paper, a method for the synthesis of ractopamine molecularly imprinted polymers (MIPs) nanotube membranes on anodic alumina oxide (AAO) nanopore surface by atom transfer radical polymerization (ATRP) was presented, in which methacrylic acid (MAA) was selected as functional monomer with a polymerization rate of 1:6 between ractopamine and MAA by the computational investigations. The morphology of MIPs nanotube membranes characterized by scanning electron microscope (SEM) suggested a well growth in the AAO nanopore surface. A series of adsorption experiments revealed that the MIPs nanotube membranes showed better extraction capacity and good selectivity for ractopamine and its analogues than that of non-imprinted polymers (NIPs) nanotube membranes. In order to evaluate the usability of the MIPs nanotube membranes, a methodology by combining MIPs nanotube membranes extraction couple with high performance liquid chromatography (HPLC) detection for the determination of beta2-agonists in complex samples was developed. The linear ranges were 10-1000mug/L for ractopamine, 100-1000mug/L for clenbuterol, epinephrine and dopamine, and 200-1000mug/L for terbutaline. The detection limits were within the range of 0.074-0.25mug/L and the RSDs (n=3) were from 2.8% to 4.3%. The method was successfully applied to the analysis of beta2-agonists in spiked real samples, The recoveries of all the beta2-agonists at the two concentration levels were found to be within the range of 86.3-97.0% and 82.8-95.7%, respectively. The RSDs were within 2.7-5.7%. The results demonstrated that the proposed method is very suitable for the determination of beta2-agonists in pork samples.
