Synthesis new organic azo dye as reagent 3-((4-acetyl-3-hydroxyphenyl) diazenyl)-4-amino-N-(5-methylisoxazol3-yl)benzene sulfonamide (SDA) and Analytical Study of Co(II), Ni(II) and Cu(II), metals complexes. The reagent and its complexes were characterized by elemental analysis, UV-Vis, and molar conductivity measurements. The data show that the complexes have the composition of [MR]X2 type. Th...

The temperature dependence of the density, dynamic viscosity and ionic conductivity of several deep eutectic solvents (DESs) containing ammonium-based salts and hydrogen bond donvnors (polyol type) are investigated. The temperature-dependent electrolyte viscosity as a function of molar conductivity is correlated by means of Walden's rule. The oxidation of ferrocene (Fc/Fc+) and reduction of cob...

A polymerizable ionic liquid, N,N-diethyl-N-(2-methacryloylethyl)-N-methylammonium bis(trifluoromethylsulfonyl)imide (DEMM-TFSI), was polymerized via copper-mediated atom transfer radical polymerization (ATRP). The polymerization proceeded in a living manner producing well-defined poly(DEMM-TFSI) of target molecular weight up to about 400 K (including a polycation and an counter anion). The acc...

New Pd(II) and Pt(II) complexes of the type [M(bzoS)2(diamine)] {where M = or } from treatment one mole diamine ligands {diamine , phenanthroline (Phen), bipyridine (Bipy), ethylene (en), N,N′-dimethyl (dmen)} with [M(bzoS)2] complexes. The prepared were characterization by elemental analysis (CHN), molar conductivity, infrared spectroscopy, nuclear magnetic resonance proton (1H NMR). bzoS- lig...

Graphene ink is a commercialized product in the graphene industry with promising potential application in electronic device design. However, the limitation of the graphene ink is its low electronic performance due to the ink preparation protocol. In this work, we proposed a simple post-treatment of graphene ink coating via electrochemical oxidation. The electronic conductivity of the graphene i...

Six new copper(II)–lanthanide(III) heterobinuclear complexes, described by the formula Cu(obbz)Ln(Me2-phen)2NO3 (Ln = La, Nd, Gd, Tb, Ho, Er), where obbz denotes the oxamidobis(benzoato) and Me2-phen represents 2,9-dimethyl-1,10-phenanthroline (Me2-phen), have been synthesized and characterized by the elemental analyses, spectroscopic (IR, UV, ESR) studies, magnetic moments (at room temperature...

The crystal structure of the copper(II) complex has been determine...

We describe the synthesis and characterization of two new zinc (II) and cadmium (II) complexes of the tetradentate dissymmetric Schiff base ligand 2-((E)-(2-(2-(pyridine-2-yl)ethylthio)ethylimino)methyl)-4-bromophenol (PytBrsalH), prepared from 1-(2-pyridyl)-3-thia-5-aminopentane (pyta) and 5-bromosalicylaldehyde. The complexes were synthesized by treating an ethanolic solution of the ligand wi...
