Theoretical study of the structure and tautomerism of an asymmetric diimine Schiff base, preparation and characterization of its modified electrode

Year 2017, Volume: 30 Issue: 4, 124 - 138, 11.12.2017

Abstract



An asymmetric diimine
Schiff base,
2-((E)-4-((E)
-2-hydroxybenzylideneamino) benzylideneamino) phenol, was covered to a glassy carbon (GC) electrode
surface in nonaqueous medium to fabricate a modified electrode.
Cyclic
voltammetry was applied for
the surface modification experiments in 1
mM diimine solution. Cyclic voltammetry
, contact angle measurement, electrochemical
impedance
spectroscopy and X-ray
photoelectron spectroscopy techniques were employed to characterize
the modified GC (diimine-GC)
surface. Electrochemical impedance results showed that the modified surface
blocked the electron transfer with a 98.9% surface coverage value.
Additionally, theoretical study was performed to gain
insight into the structural and tautomeric aspects of the
diimine Schiff base. The phenol-imine and keto-amine tautomerism forms of the diimine Schiff base were investigated by using DFT calculations.
