The purpose of this work was to prepare efficient models of cytochrome P450, hemoglobin and cytochrome c oxidase, by various synthetic modifications on a phenanthroline-strapped porphyrin (Porphen). In particular, a new model of cytochrome c oxidase was analyzed here. This compound was obtained by substitution of both meso positions of a Zn-Porphen. Dynamics phenoma were observed and analyzed by 1H NMR, showing the presence of atropoisomers and coordination-decoordination of the proximal pyridine on zinc. Zinc was then replaced by iron, which allows the coordination of a sixth exogenous ligand in the dynamic distal site. The evolution of the complexes’ geometry was monitored by UV-Visible spectrophotometry and EPR. In the presence of imidaz...
