Studying the structure and the dynamical behavior of self-assembled porphyrins is an attractive subject in many fields of research. In particular, the quest for new organometallic catalysts to reduce oxygen to water is a major challenge and has a large range of applications, especially in energy research where porphyrins and corroles have been widely studied. The selectivity towards the four-electron reduction of oxygen of synthetic binuclear complexes, such as Co2(FTF4) and Pacman porphyrins adsorbed onto edge plane pyrolytic graphite electrodes, is about 100 and 80, respective-ly.
