Effects of the Cationic Structure on the Adsorption Performance of Ionic Polymers toward Au(III): an Experimental and DFT Study was written by Kou, Xin;Ma, Yutian;Pan, Congming;Huang, Yong;Duan, Yulai;Yang, Ying. And the article was included in Langmuir in 2022.Related Products of 628-13-7 This article mentions the following:

Ionic polymers have been proven to be promising adsorbents in recovering Au(III) due to their advantages of simple synthesis and high adsorption efficiency. However, the unclarity of the relationship between the adsorption ability of ionic polymers and their cationic structures hinders further optimization of their adsorption performance. This study synthesized a series of ionic polymers with pyridinium, imidazolium, piperidinium, pyrrolidinium, and triethylammonium cations to discover the effects of the cationic structure on their adsorption properties. Exptl. results show that the existence of anion-π interaction between aromatic cations and [AuCl4]– makes the aromatic cations-anion interaction stronger, which does not enhance the adsorption performance of the aromatic-based ionic polymer. This is due to the charge delocalization in the aromatic ring, resulting in a lower electrostatic potential (ESP) of aromatic cations than that of aliphatic cations with a localized charge. The higher the ESP of cations, the better the adsorption performance of the corresponding ionic polymer. This study serves as a deep understanding of the cationic structure-adsorptive performance relationship of the ionic polymer at the mol. level and further provides a theor. guidance to optimize the adsorption performance of ionic polymers.

CuI incorporated cobalt ferrite nanoparticles as a magnetically separable catalyst for oxidative amidation reaction

A Cu-incorporated magnetic nanocatalyst (CoFe2O4@SiO2-SH-CuI) has been developed by immobilizing CuI on the modified surface of CoFe2O4 magnetic nanoparticles. The surface of the silica coated cobalt ferrite magnetic core was first treated with 3-mercaptopropyl triethoxysilane to produce the thiol functionalized nanoparticle CoFe2O4@SiO2-SH. Further treatment of the nanoparticle with CuI produced the desired magnetic nanocatalyst. The versatility of the catalyst has been demonstrated for the synthesis of N-(pyridin-2-yl) benzamide via oxidative amidation of aryl aldehydes with 2-amino pyridine in the presence of an oxidant. The reaction was carried out in DMSO at 80 degrees C using TBHP (70% aqueous) in the presence of 20 wt% of the catalyst. Notably, the catalyst could be separated from the reaction mixture in the presence of an external magnetic field. During the study, a new compound N-(pyridin-2-yl)anthracene-2-carboxamide has been synthesized and its turn on fluorescence sensing properties towards various metal ions have been studied. Fluorescence experiments and theoretical studies indicated that the newly synthesized carboxamide molecule can be used for fluorescence sensing of the Hg2+ ion in aqueous solution.

Development of Sensor Based on Copper(II) Thiocyanate Pyridine Polymeric Complex for Detection of Catechol

The reaction of copper(I) thiocyanate with triphenylphosphine, in pyridine, in air and at room temperature, led to the formation of the copper(II) thiocyanate pyridine polymeric complex [Cu-2(mu 3CO3)(NCS)(2)(Py)(4)] n in the form of deep blue needle-like crystals. Fourier transform infrared spectroscopy (FTIR), elemental analysis (EA), thermogravimetric analysis (TGA) and single crystal X-ray diffraction analysis (XRD) were performed in order to reveal the identity of the obtained complex. The complex is a coordination polymer that crystallizes in the orthorhombic space group Pnma and has a one-dimensional linear structure running along the crystallographic a axis. Here, we report the investigation of the electrochemical properties of this polymeric compound, collected in acetonitrile solution and KClO4 as electrolyte, by cyclic voltammetry and square wave voltammetry. The voltammograms showed four peak pairs related to redox processes of copper ion and electroactive ligands. Moreover, we used this compound as modifier of carbon paste electrodes, whose electrochemical properties were studied in different electrolytes and electrochemical redox probes. These studies demonstrate the valuable electrochemical and electrocatalytic properties of the [Cu-2(mu(3)-CO3)(NCS)(2)(Py)(4)](n) polymerimmobilized in the carbonaceous matrix. The sensor developed by using the carbon paste method has shown excellent sensitivity for catechol, good repeatability, selectivity, stability, and applicability in detection of catechol in water samples.

Coordination behavior of succinylsulfathiazole – Crystal structure of [Cu(SST)(center dot)(Pyridine)(3 center dot)H2O](n), DNA interaction and cytotoxic studies

Mononuclear copper complex of succinylsulfathiazole has been synthesized and characterized using relevant spectroscopic and X-ray diffraction techniques. EPR data and X-ray structural analysis confirmed that Cu(II) ion exhibits an intermediate geometry between trigonal and square bipyramid. Succinylsulfathiazole (SST) ligand behaves as a head-to-tail bridging moiety linking two metal (Cu) cations via carbonyl oxygen and thiazolate nitrogen atom, resulting one dimensional polymeric chain running along [010] direction. In the mononuclear copper complex formulated as [Cu(SST)(center dot)(Pyridine)(3 center dot)H2O](n), three nitrogen atoms of three secondary ligand pyridines coordinated to copper at the equatorial plane, the fourth coordination of distorted pentadentate copper is due to thiazolate nitrogen (N3) occupying the apical position and carbonyl oxygen (O1) of SST ligand at x + 1/2, y-1/2, z-1/2 remaining at fifth coordination site completes the coordination sphere of copper. The inversely related Cu-SST molecular complexes are held together by pair of N-H center dot center dot center dot O dimer forming R-2(2) (14) graph set motif which are further connected by water oxygen (O6) via O-H center dot center dot center dot O interactions. Quantitative contributions of intermolecular interactions are worked out using Hirshfeld surface (HS) and 2D fingerprint plots. Lipophilicity index (Log P), correlates well with the% contribution of C-H center dot center dot center dot pi interaction. To evaluate the binding capabilities and binding mode of molecular complex with CT-DNA, absorption study and viscosity measurement are carried out, confirming the intercalation mode of binding which is further supported by molecular docking studies. In vitro cytotoxicity screening of the complex have been performed on zoological species Artemia cyst. (C) 2020 Elsevier B.V. All rights reserved.

Copper complexes for the promotion of iminopyridine ligands derived from beta-alanine and self-aldol additions: relaxivity and cytotoxic properties

In the study presented herein, we explore the ability of copper complexes with coordinated pyridine-2-carboxaldehyde (pyca) or 2-acetylpyridine (acepy) ligands to promote the addition of amines (Schiff condensation) and other nucleophiles such as alcohols (hemiacetal formation). Distinct reactivity patterns are observed: unlike pyca complexes, acepy copper complexes can promote self-aldol addition. The introduction of a flexible chain via Schiff condensation with beta-alanine allows the possibility of chelate ring ring-opening processes mediated by pH. Further derivatization of the complex [CuCl(py-2-C(H)?NCH2CH2COO)] is possible by replacing its chloride ligand with different pseudohalogens (N-3(-), NCO- and NCS-). In addition to the change in their magnetism, which correlates with their solid-state structures, more unexpected effects in their cytotoxicity and relaxitivities are observed, which determines their possibility to be used as MRI contrast agents. The replacement of a chloride by another pseudohalogen, although a simple strategy, can be used to critically change the cytotoxicity of the Schiff base copper(ii) complex and its selectivity towards specific cell lines.
