In this work, two novel dinuclear cobalt complexes, [CoII(hbqc)(H2O)]2 (Co-Cl) and [CoII(hbqn)(H2O)]2 (Co-NO2), featuring benzimidazole derived redox-active ligand have been synthesized to investigate their catalytic activities toward electrocatalytic proton reduction (where hbqc is 2-{[6-chloro-2-(8-hydroxyquinolin-2-yl)-1H-benzimidazol-1-yl]methyl}quinolin-8-ol hbqn 2-{[6-nitro-2-(8-hydroxyquinolin-2-yl)-1H-benzimidazol-1-yl]methyl}quinolin-8-ol). The electrochemical responses in 95/5...
Two dinuclear Co II complexes 1 and 2 have been synthesized characterized using various spectroscopic methods. Both the were employed for H + reduction in organic media. Faradaic efficiency of 82–90% was obtained evolution.
The investigation into a prospective pharmaceutical chalcone derivative employs comprehensive methodology, integrating theoretical and empirical analyses. Rigorous scrutiny of the compound's distinct attributes is conducted through FT-IR, NMR UV-Vis spectroscopy. Utilizing Density Functional Theory (DFT), specifically B3LYP/6–311++G(d,p), yields crucial insights potential energy surface, molecular structure optimization, vibrational properties, electronic configuration stability. study...
Quinoline‐based benzimidazole compounds have been successfully synthesized and characterized by various spectroscopic techniques like FT‐IR, 1 H NMR, 13 C mass spectral analysis, the structures authenticated single crystal X‐ray diffraction method. Here, we report an economical, mild, efficient procedure that involves condensation of 8‐hydroxyquinoline‐2‐carbaldehyde with diamines as substrates to give bis ‐imines. A systematic study towards both aliphatic aromatic ‐imines has conducted...
A novel dinuclear copper complex, [CuII2(L1)2] (L1 = 2-{[2-(8-hydroxyquinolin-2-yl)-1H-benzimidazol-1-yl]methyl}quinolin-8-ol) was synthesised and characterised through various spectroscopic techniques. This complex (as an electrocatalyst) employed to examine the catalytic ability towards electrochemical hydrogen evolution reaction (HER). Redox studies in 95/5 (v/v) DMF/H2O with addition of 30-equivalent AcOH (acid source) led higher activities for HER. The evolved H2, as resultant product,...
The new ligand Ql-tpy (8-(2,6-di(pyridin-2-yl)pyridin-4-yl)quinoline) and the corresponding aqua complex [Ru(Ql-tpy)(bpy)(OH2)](PF6)2 (1) have been synthesized characterized by different spectroscopic methods. This shows two pKa values, pKa1 due to deprotonation from protonated N atom located on quinoline moiety at 3.0 another pKa2 10.5 ligand. catalytic activity of 1 towards water oxidation was studied in CF3SO3H solution (pH ≈ 1) using CeIV as an oxidant. free substituted gets pH acts...
Abstract The employment of manganese complexes towards electrocatalytic water oxidation has gained immense interest among the scientific communities. In this present study, reaction Mn(CH 3 COO) 2 ⋅4H O with novel ligand (2‐([2,2′:6′,2“‐terpyridin]‐4′‐yl)quinoline‐8‐ol) ( 8hq‐tpy ) affords a dinuclear complex, [Mn II (8hq‐tpy)(H O)] (PF 6 Mn 1 ). Various spectroscopic techniques have been implemented for characterization purposes, and is employed as electrocatalysts catalysis in aqueous...
