The rich and wide redox chemistry of N4 metal macrocyclic complexes allied to the several strategies for immobilizing them on the surface of different types of solids 21/10/2019В В· A general overview of the benefits of using SECM as an alternative or as a complimentary technique to rotating-ring disk electrode (RRDE) voltammetry in studying the kinetics of the ORR is provided, with examples of this application dedicated to catalysts derived from MN 4-macrocyclic complexes.
Synthesis, Properties and Applications of Macrocyclic Azobenzenes Inauguraldissertation zur Erlangung der Würde eines Doktors der Philosophie vorgelegt der Philosophisch-Naturwissenschaftlichen Fakultät der Universität Basel von Raphael Reuter aus Weil am Rhein, Deutschland Basel, 2011 21/04/2016 · Abstract. N 4-macrocyclic complexes are among the most widely investigated molecular materials for the oxygen reduction reaction (ORR). These complexes are attractive because they inherently provide well-defined structural models for describing the ORR not only in nature, for example, in cytochrome c oxidases, but also for electrocatalysts of
25/10/2017В В· Alternatively, lead compounds may be obtained by truncation and modification of macrocyclic natural products. Selected medicinal chemistry programs are discussed, illustrating a macrocyclization approach toward ligands with improved properties. The design of such ligands is often informed by X-ray crystal structures of protein-ligand complexes. Biomedical applications of macrocyclic ligand complexes Ryan E. Mewis , Stephen J. Archibald Coordination Chemistry Reviews 2010 254 (15-16), 1686-1712
