Synthesis, Characterizations and Investigation of Electrochemical Behaviours of 4-[(2-Hydroxyphenylimino)methyl]benzene-1,3-diol

Abstract

This Schiff base ligand, 4-[(2-hydroxyphenylimino) methyl]benzene-1,3-diol (HIBD) was synthesized by reaction of 2-aminophenol and 2,4-dihydroxybenzaldehyde. The ligand was characterized by elemental analysis, FT-IR and ¹H-NMR. Electrochemical behaviors were investigated on the glassy carbon electrode (GC) surface with cyclic voltammetry (CV). The modification of HIBD on the GC was performed in +0.3 V and +2,8 V potential range using 100 mV s^-1 scanning rate having 5 cycle. For the characterization of the modified surfaces 1 mM ferrocene redox probe in 0,1 M tetrabutylammonium tetrafluoroborate (TBATFB) and 1 mM ferricyanide redox probe in 0.1 M H₂SO₄ were used.
