The covalent linkage between caffeine units and a benzothiadiazole core lead to molecules with electrochemical properties that differ from both individual components and is therefore an interesting strategy to modulate and tune the reactivity of small molecules for applications in catalysis. Cyclic voltammetry (CV, Figure ) and differential pulse voltammetry (DPV, Figures and) were performed to study the electrochemical properties of BT-MCAF and BT-DCAF. As shown in Figure , molecular caffeine does not have a reduction peak within the electrochemical potential window of DMSO.
