Electrochemistry of Mono- and Bis-CN Ligated Cobalt Corroles

International audience; The electrochemical properties of numerous transition metal corroles have been examined under a variety of<br&gtsolution condition with special emphasis being placed on the innocent or non-innocent nature of the corrole<br&gtmacrocycle. This property, as well as the half-wave potentials and sites of electron transfers, are known to be<br&gtstrongly influenced by the type of central metal ion and degree of axial coordination, namely 4, 5 or 6-coordinate.<br&gtThe redox potentials of metallocorroles are also dependent upon the solvent and inductive, resonance or steric<br&gteffects dictated by peripheral substituents at the meso or β-pyrrole positions of the corrole li…
