Reaction control for oxygen reduction by covering the electrode with a metal chelate

Synthesis and Characterization of Co(II), Ni(II), Cu(II), Zn(II) and Cd(II) Complexes With Polydentate 14-Membered Macrocyclic Ligand

“…The chemistry of metal macrocycles is extensive because of their close relationship to molecules of biological significance (2)(3)(4)(5)(6) . The importance of these complexes is due to the role they play as models for protein metal binding sites in biological systems, as synthetic ionophores (7) , electrocatalysts in fuel cells (8) , MRI contrast agents (9,10) , luminescent sensors (11) , anticancer drugs (12) and radioimmunotherapeutic agents (13) . These extensive applications have been worth investigating for the design of new macrocyclic ligands for biological and industrial applications.…”
