Description

Electrochemical systems underpin a wide range of modern energy technologies by enabling efficient energy conversion and storage. Interfacial electrochemical processes can be broadly classified into charge-transfer reactions and charge-accumulation phenomena. Charge-transfer processes, governed by electrocatalysts, dictate reaction kinetics in energy-related devices, whereas charge accumulation arises from the formation of an electrical double layer, leading to capacitive currents whose relevance depends on the application. Suppressing capacitive contributions is essential for improving sensitivity in electrochemical sensing, while enhancing them is advantageous for maximizing energy storage in supercapacitor systems. Consequently, precise control over both charge-transfer and charge-storage mechanisms is critical for optimizing electrochemical performance.

Molecular systems, such as phthalocyanines and porphyrins, provide versatile platforms for modulating electrochemical behavior due to their high chemical and thermal stability, as well as tunable optoelectronic properties. Among these, metal phthalocyanines are of particular interest owing to their superior electrochemical performance compared to metalloporphyrins, arising from enhanced π-conjugation that facilitates electron transfer and a rigid macrocyclic framework that ensures greater stability under electrochemical conditions. This work highlights the role of molecular systems in regulating charge-transfer and charge-storage processes and identifies existing gaps in structure–activity relationships. To address these gaps, a combined electrochemical and spectroscopic approach is employed, focusing on ligand-assisted modulation of interfacial processes to elucidate ligand-dependent electrochemical behaviour.
