Synthesis and electrochemical properties of new tetra substituted cobalt phthalocyanine complexes, and their application in electrode modification for the electrocatalysis of l-cysteine

▶ Mercaptoquinoline cobalt phthalocyanines have been synthesised. ▶ Cyclic voltammetry shows both ring and metal based processes. ▶ Complexes were used to modify carbon or gold electrodes. ▶ Electrodes were used to electrocatalytically oxidize l-cysteine.
