Abstract:
This work reports on the electrochemical behaviour of Fe and Zn based metal organic framework (MOF) compounds, which are “doped” with chiral molecules,
namely: cysteine and camphor sulfonic acid. Their electrochemical behaviour was
thoroughly investigated via “solid-state” electrochemical measurements,
exploiting an “ad hoc” tailored experimental set-up: a paste obtained by
carefully mixing the MOF with graphite powder is deposited on a glassy carbon
(GC) surface. The latter serves as the working electrode (WE) in cyclic voltammetry
(CV) measurements. Infrared (IR), X-ray diffraction (XRD) and absorbance (UV-Vis)
techniques are exploited for a further characterization of the MOFs’ structural and
electronic properties. The experimental results are then compared with DFT based
quantum mechanical calculations. The electronic and structural properties of the
MOFs synthesized in this study depend mainly on the type of metal center, and to a
minor extent on the chemical nature of the dopant.
