Electrochemical Characterization of (1E)-1-N-{[4-(4-{[(E)-N-(3-aminophenyl) Carboxyimidoyl] Phenoxy} Butoxy) Phenyl] Methilidene} Benzene-1,3-diamine

Abstract

Oxido-reduction properties of a newly synthesized Schiff base were investigated  by cyclic voltammetry and differential pulse voltammetry. Measurements were conducted in a three electrode voltammetric cell in a non-aqueous media. Glassy carbon was used as a working electrode, platinum wire as counter electrode and non-aqueous Ag/Ag⁺ electrode as a reference electrode. Inert atmosphere was acomplished by system purging with high purity argon Ar 5 (f_Ar = 99,999 %),before each measurement. Cyclyc voltammograms revealed one oxidation peak of the investigated Schiff base (E_p,a = 0.69 V), which increased with increasing concentration (c = 3.1 ·10^-5 mol dm^-3...  1.25 ·10^-4 mol dm^-3) and scan rate (ν = 50...300 mV/s). Differential pulse voltammetry showed one oxidation peak E_p,a = 0,69 V, which also increased with increasing concentration.
