title: Formation of a Pt12 cluster by single-atom control that leads to enhanced reactivity: hydrogenation of unreactive olefins.
abstract: A platinum subnanocluster catalyst composed of 12 atoms was synthesized using a phenylazomethine dendrimer, which can assemble twelve PtCl4 units by stepwise complexation, followed by reduction to Pt(0). Unreactive olefins that were not activated by conventional 2 nm Pt nanoparticles were successfully hydrogenated by the subnanocluster. EWG = electron-withdrawing group.
