Ruggi Group has recently published an article in the journal ChemSusChem, entitled; "Rationalizing Photo-Triggered Hydrogen Evolution Using Polypyridine Cobalt Complexes: Substituent Effects on Hexadentate Chelating Ligands". It is also highlighted on the cover feature of the journal. Congratulations!

Abstract 

The Cover Feature shows the structure–activity relationship of a family of heptacoordinate Co^II complexes for light?triggered H₂ evolution. The complexes present a ligand scaffold including bipyridines and pyridines moieties functionalized with either electron?donating or electron?withdrawing groups. Results show that position plays a predominant role with respect to the electronic effect of the substituents.
