Electrocatalytic reduction of oxygen with phenanthroline-strapped porphyrins

Autor: Philippe Ochsenbein, Jean Weiss, Maurice Gross, Michel Bonin, Kurt Schenk, Corinne Boudon, Mamadou Lo, Frederic Melin

Publikováno v: Scopus-Elsevier

The electrochemical behavior of three cytochrome c oxidase models has been investigated. All the models are derived from a phenanthroline-strapped, porphyrin framework that binds zinc(II) or iron(III) chloride in the porphyrin subunit, and copper(I)

Publikováno v: Chemistry - A European Journal. 11:3711-3727

As an alternative to conventional charge-separation functional molecular models based on long-range ET within redox cascades, a "compact approach" has been examined. To this end, spacer elements usually inserted between main redox-active units within

Publikováno v: Angewandte Chemie International Edition. 50:11637-11639

Crystal clear: After two decades of controversy the elusive skew-boat conformation of L-iduronic acid (see picture) was finally ascertained at atomic resolution in a synthetic, substituted disaccharide. This highly flexible compound crystallizes in t

Publikováno v: Chemistry - A European Journal. 7:2676-2686

Representative metal complexes of a biconcave D4-symmetric porphyrin were synthesised by metal-ion insertion into the porphyrin ligand 1. The NMR spectra suggested D4-symmetry for the ZnII and dioxo-RuVI complexes of 1 and C4-symmetry for the unsymme
