Slow Magnetic Relaxation in a [Na2Dy4] Complex and Coexistence of Multiple Metal Rings

Three rare isostructural heterometallic complexes [Na-2{Ln(4)(mu(3)-OH)(2)(ppt)(4)(Hppt)(2)(OAc)(2)}(DMF)(4)] . xH(2)O (H(2)ppt=3-(2-hydroxyphenyl)-5-(pyrazin-2-yl)-1,2,4-triazole, x=2.5, Ln=Dy (1); x=2, Ln=Er (2); x=0, Ln=Yb (3)) have been obtained. The structural analysis displayed that two Na-I and four Ln(III) ions were linked together through N-N groups and O atoms to form a metallmacrocycle with the connectivity pattern [Dy-O-Na-N-N-Dy-O](2). Such cases possess rare hexametallic ring, which further displays one tetrametallic and two trimetallic cyclic units. Magnetic measurements reveal single-molecule magnet (SMM) behavior for 1 with the effective energy barrier of 51.6 K and pre-exponential factor of 6.16×10(-6) s deduced from frequency-dependent magnetic susceptibilities. Ab initio calculations prove that the weak ferromagnetic coupling mainly originats from the dipolar interaction. The transversal magnetic moments in the ground Kramers could suppressed the quantum tunneling of magnetization.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 693-23-2. SDS of cas: 693-23-2.

Enantioselective Analysis and Degradation Studies of Four Stereoisomers of Difenoconazole in Citrus by Chiral Liquid Chromatography-Tandem Mass Spectrometry

Four difenoconazole stereoisomers were well separated on a Superchiral S-OX column. The absolute configurations of the four stereoisomers of difenoconazole eluted in an orderly fashion with the chiral column were confirmed as (2S,4S), (2S,4R), (2R,4R), and (2R,4S)-difenoconazole, respectively, by single-crystal X-ray diffraction. For the first time, a simple and efficient trace detection method for the determination of residues of the four stereoisomers of difenoconazole in a plant sample by HPLC-MS/MS was developed. The mean recoveries were 78.23-104.38% with RSDs of 0.33-9.95%. The limits of detection for the four difenoconazole enantiomers were 0.0002-0.0004 mg/kg, and the limits of quantitation were 0.0044-0.011 mg/kg in citrus leaves and whole fruits. There was no obvious enantioselectivity upon degradation of the four stereoisomers in citrus leaves and whole fruits in Hunan and Guizhou. In Guangzhou, the rate of degradation of (2R,4R)-difenoconazole was the slowest among the four stereoisomers of difenoconazole.

A Cu-4 cluster-based MOF as a supercapacitor electrode material with ultrahigh capacitance

Developing new pristine metal-organic framework (MOF)-based electrode material for high-performance supercapacitors is a considerable attractive task. Herein, a Cu-4 cluster-based three-dimensional (3D) MOF ([Cu-4(mu(3)-OH)(2)(atrz)(2)(1,3-BDC)(3)]center dot 2H(2)O, Cu-atrz-BDC; atrz, 4-amino-1,2,4-triazole; 1,3-H2BDC, 1,3-benzenedicarboxylic acid) was synthesized and characterized by infrared spectroscopy, X-ray powder diffraction, thermogravimetric analysis, nitrogen adsorption-desorption, scanning electron microscopy, and X-ray photoelectron spectroscopy. The Cu-atrz-BDC firstly was used as an electrode material for supercapacitor. In a three-electrode system, the Cu-atrz-BDC electrode exhibited ultrahigh specific capacitance of 5525 F g(-1) at 1 A g(-1) and its specific capacitance can also keep about 886 F g(-1) after 1000 cycles at 3 A g(-1). Importantly, the Cu-atrz-BDC as the positive electrode and the rGO as the negative electrode were assembled into an asymmetric supercapacitor with excellent cycling stability, displaying the maximum energy density of 9.96 Wh kg(-1) at a power density of 0.81 kW kg(-1). The high supercapacitive performance might be ascribed to its porous three-dimensional structure, the nanosized particles, and better conductivity.

Stereoselective in vitro metabolism of cyproconazole in rat liver microsomes and identification of major metabolites

The vast usage of agrochemicals enhances food security globally but may pose challenge to understand the risk assessment to non-target organisms and human beings, and liver microsomes are responsible for metabolism of these agrochemicals in vivo. In this study, stereoselective metabolism of chiral triazole fungicide cyproconazole in rat liver microsomes has been investigated through chiral LC-MS/MS technique. The half-lives of four cyproconazole stereoisomers were different ranging from 95 to 187 min, and (2S, 3R)-cyproconazole preferentially metabolized in rat liver microsomes. In addition, the results from metabolism kinetic study indicated that rat liver microsomes showed the stronger potency to deplete (2S, 3R)-cyproconazole than the others. Then, homology modeling and molecular docking results revealed that the docking energy between (2S, 3R)-cyproconazole and the cytochrome P450 CYP3A1 (-7.46 kcal.mol(-1) ) was higher than the others, meaning that (2S, 3R)-cyproconazole exhibited the strongest binding ability to this enzyme. Moreover, two main metabolites of cyproconazole coming from hydroxylation and dehydration were observed, and possible metabolic reactions of cyproconazole in rat liver microsomes were identified through using an LCQ ion trap mass spectrometer. This kind of systematic metabolic investigation of cyproconazole at chiral level would provide valuable information for ecological and human health risk assessment of chiral pesticides.

Highly Selective Separation Intermediate-Size Anionic Pollutants from Smaller and Larger Analogs via Thermodynamically and Kinetically Cooperative-Controlled Crystallization

Selective separation of organic species, particularly that of intermediate-size ones from their analogs, remains challenging because of their similar structures and properties. Here, a novel strategy is presented, cooperatively (thermodynamically and kinetically) controlled crystallization for the highly selective separation of intermediate-size anionic pollutants from their analogs in water through one-pot construction of cationic metal-organic frameworks (CMOFs) with higher stabilities and faster crystallization, which are based on the target anions as charge-balancing anions. 4,4 ‘-azo-triazole and Cu2+ are chosen as suitable ligand and metal ion for CMOF construction because they can form stronger intermolecular interaction with p-toluenesulfonate anion (Ts-) compared to its analogs. For this combination, a condition is established, under which the crystallization rate of a Ts–based CMOF is remarkably high while those of analog-based CMOFs are almost zero. As a result, the faster crystallization and higher stability cooperatively endow the cationic framework with a close-to-100% selectivity for Ts- over its analogs in two-component mixtures, and this preference is retained in a practical mixture containing more than seven competing (analogs and inorganic) anions. The nature of the free Ts- anion in the cationic framework also allows the resultant CMOF to be recyclable via anion exchange.

Simultaneous enantiomeric determination of multiple triazole fungicides in fruits and vegetables by chiral liquid chromatography/tandem mass spectrometry on a bridged bis(beta-cyclodextrin)-bonded chiral stationary phase

A LC-MS/MS method for simultaneous determination of twelve triazole enantiomers (hexaconazole, tebuconazole, triticonazole, flutriafol, diniconazole, paclobutrazol) in six fruits and vegetables was established based on a stable and self-made bridged bis(beta-cyclodextrin)-bonded chiral stationary phase. Simultaneous enantio-separation of multiple analytes was achieved with resolution ca. 1.67-2.14. Magnetically assisted QuECHERS was used to simplify and optimize sample pre-treatment. The new method was validated (accuracy, precision, matrix effect, etc.). Good linearity (0.5-20 mu g/L, R-2 > 0.99) and high recoveries (76.1-103.4%) based on intra- and inter-day relative standard deviation (RSDs) (2.6-11.9%), were obtained. Furthermore, a total of 90 samples were analyzed using this method and enantiomeric fractions (EF) for tebuconazole in strawberry and cucumber (0.63 and 0.43, respectively) were determined as well as 0.57 for flutriafol in tomato. This high-throughput detection method supported a convenient enantiomeric monitoring for chiral pesticides in fruits and vegetables.
