Abstract The synthesis and electrochemical characterization of a new azulene‐thiourea like complexing monomer namely, (2E)‐2‐(azulen‐1‐ylmethylidene) hydrazinecarbothioamide ( L ) is reported. electropolymerization in acetonitrile on glassy carbon electrodes, put evidence by EQCM ferrocene redox assay probe, led to the immobilization electrode surface. poly modified electrodes were electrochemically characterized their morphology was evaluated using scanning electron microscopy. abilities...
A computational study on three related derivatives of 5-[(azulen-1-yl)methylene]-2-thioxoimidazolidin-4-one was conducted using density functional theory by calculating a series molecular descriptors and properties their optimized geometries (electrostatic local ionization potentials, frontier orbitals, etc.). Thermodynamic (zero-point energy, enthalpy, constant volume heat capacity, entropy Gibbs energy) for these have been calculated to ligands electrochemical behavior. Reduction oxidation...
A new azulene (L 2352) synthesized in the laboratory was used for design of a stochastic sensor. L 2352 physically immobilized graphite paste. Four metallic cations: Cu(II), Pb(II), Hg(II) and Cd(II) served as model analytes. The sensor reliable to prove behavior proposed microsensors. metal cations were determined directly from nine waste water.
This paper focuses on electrochemical characterization of new azulene compound 2,6-bis((E)-2-(thiophen-3-yl)vinyl)-4-(4,6,8-trimethylazulen-1-yl)pyrylium (L) by cyclic voltammetry (CV), differential pulse (DPV), rotating disk electrode (RDE) glassy carbon working electrodes. The character redox processes was established CV and RDE using increasing scan rates at different domains. PolyL modified electrodes have been prepared scanning or controlled potential electrolysis (CPE). complexing...
This study develops a new electrochemical method for quantification of Pb in soft water using stripping voltammetry with glassy carbon electrode modified the functionalized azulene: (2E)-2-(azulen-1-ylmethylidene) hydrazine carbothioamide (L) as complexing polymer film. The optimized steps proposed consisted experimental establishing four parameters, namely: reduction time; potential; complexation pH acetate buffer and phosphate buffer. electrodes were prepared L solutions (1mM) acetonitrile...
