A number of redox-active coordination polymers (CPs) or metal- organic frameworks (MOFs) have been successfully synthesized using transition metals and bridging ligands. This article aims to deal with gathering the aforementioned disperse issues regarding the electroactive CPs. It also goes towards illustrating the effects of various factors on the electrochemical behavior of CPs including...

Here, we report a new di(hydroxyphenyl)imidazolate ligand with an N2O2 donor set synthesized by modified Debus–Radziszewski procedure. Its binuclear nickel(II) complexes feature weak antiferromagnetic interaction J12 = −3.16 cm−1 between the two ions identified magnetometry measurements. As follows from cyclic voltammetry experiments and DFT calculations, they undergo ligand-centered oxidation ...

Four novel polypyridine cobalt(II) complexes were developed based on a hexadentate ligand scaffold bearing either electron-withdrawing (−CF3) or electron-donating (−OCH3) groups in different positions of the ligand. Experiments and theoretical calculations combined to perform systematic investigation effect modification hydrogen evolution reaction. The results indicated that position, rather th...

Biological systems are often exposed to mechanical perturbations, which may modulate many biochemical processes. Ligand binding involves a wide range of structural changes in the receptor protein, from hinge movement entire domains minor sidechain rearrangements pocket residues. Hydrophobic ligand protein alters system’s vibrational free energy, allowing different conformational states alloster...

It is well known that flagellated bacteria, such as Escherichia coli , sense chemicals in their environment by a chemoreceptor and relay the signals via well-characterized signaling pathway to flagellar motor. widely accepted change rotation bias of motor without influencing speed. Here, we present results contrary show bacteria also capable modulating speed on merely sensing ligand. Step chang...

A novel ternary Schiff base ligand (HL) of ONO type and its copper (II) complex weresynthesised using 2-aminophenol and o-acetoacetotoluidide. They have been characterised by theusual analytical and spectral methods. The interaction of the complex with calf-thymus (CT)DNA has been investigated by UV-Vis, viscosity measurement, cyclic voltammetry anddifferential pulse voltammetry studies. The re...

Modafinil [2-[(diphenylmethyl)sulfinyl]acetamide] is used clinically in the treatment of narcolepsy and sleeping disorders. The synthesis of modafinil, begins with the reaction of benzhydrol and thioglycolic acid in trifluoroacetic acid to afford benzhydrylsulfinyl acetic acid. The reaction of acid with thionyl chloride in benzene followed by treatment with ammonium hydroxide gave acetamide...

In this study, the complexation of 2,3-dihydro-1H-phenothiazine-4(5aH)-one with 14 various cations were investigated by density functional theory. At the outset, the structures of the ligand, different cations and their derived complexes were optimized geometrically. Then, IR calculations were performed on them in order to acquire the formation enthalpy and Gibbs free energy values. The obtaine...
