Abstract

original image

Ligands as Stabilizers The cover picture represents a ligand-coated nanoparticle that is switched off (closed shell) and on (open shell showing the nanoparticle) when the ligand partially dissociates. In their Communication on page 1907 ff., P. J. Dyson et al. describe how the partial dissociation of the ligand endows the nanoparticle with stability, thus high catalytic activities can be achieved in the hydrogenation of toluene without compromising the overall stability of the catalyst, thanks to the modified bis-bipyridine ligand.
