ELECTROCHEMICAL PROPERTIES OF 2,6-BIS((E)-2-(FURAN-2-YL) VINYL)-4-(AZULEN-1-YL) PYRIDINE

The electrochemical study of 2,6-bis((E)-2-(furan-2-yl)vinyl)-4-(azulen-1-yl) pyridine (L) was performed on glassy carbon working electrode by using cyclic voltammetry (CV), differential pulse voltammetry (DPV), and rotating disk electrode voltammetry (RDE). The CV, DPV and RDE curves for L were recorded at its different concentrations in 0.1M TBAP/ CH3CN non-aqueous solution. The CV curves were also recorded at variable scan rates and on precise domains of potential to estimate the degree of reversibility of the evidenced processes. Polymeric films were formed by electrochemical oxidation either by cycling the potential in the anodic scans or by controlled potential electrolysis at different anodic potentials and charges. The obtained modified electrodes were tested as sensors for heavy metal ions.
