UV-visible absorption spectroelectrochemistry elucidated the different redox behaviours of Fe^III- and Co^III-mimochrome VI artificial enzymes, adsorbed on mesoporous conductive films of ITO. The reduction of the ferric complex was rapid and reversible, while the cobaltic complex exhibited irreversible processes probably related to multiple coordination states.
