Project

The aim of this project is the systematic study of the recently discovered “rider” coordination behaviour of surface-adsorbed porphyrines towards carbon monoxide. The study of this fundamentally new effect clearly constitutes an important and interesting long-term research program that should significantly push forward the state-of-the-art in this field. This may in turn open a new chapter in the coordination chemistry of porphyrins, with potentially important outcomes, for example in catalysis.

Preliminary results have been already published in the prestigious Nature Chemistry, and here systematic variations of the substrates, adsorbed species, porphyrin metal centers and ligands are proposed in order to understand the formation of saddle-shape configuration, and how it affects the binding of the absorbed gaz.

This project opens interesting new perspectives in the field of porphyrin’s chemistry. From the “technological” point of view, it seems that the most important applications are to be found in the field of catalysis. Indeed, the existence of a new coordination mode means that a different catalytic behaviour is to be expected, with probably an increased reactivity considering the strain associated with the “rider” ligation mode.
