dc.description.abstractNietalloporphyríns and related tetra -azamacrocyclic complexes fulfil a wide range of bioactive roles. They are employed extensively in electron -transfer catalytic cycles and as such they can exist in a variety of oxidation states. The work presented in this thesis is devoted to a study of the redox properties of series of model transition - metal porphyrin and porphyrin -like complexes.en
dc.description.abstractDetailed voltammetric studies have uniquely enabled us to evaluate the importance of back -bonding from the metal to the chelating ligand. In addition, in situ spectroelectrochemical techniques, incorporating both electronic absorption spectroscopy and ESR spectroscopy, have allowed us to unambiguously assign the electron- transfer step occurring as a metal -based or macrocycle -based redox couple. A rationalisation of the electronic spectral properties of the electrode products is presented. A re- examination of the electrochemistry of some iron and ruthenium porphyrins leads us to disagree, to a significant extent, with previous reports. We also discuss in detail the redox properties of a series of metallochlorins and utilise the results to explain the spectroelectrochemical behaviour of bonellin, a most remarkable naturally occurring macro-cycle.en
