Description
Summary:Atomic‐resolution transmission electron microscopy was used to identify individual Au9 clusters on a sulfur‐functionalized graphene surface. The clusters were preformed in solution and covalently attached to the surface without any dispersion or aggregation. Comparison of the experimental images with simulations allowed the rotational motion, without lateral displacement, of individual clusters to be discerned, thereby demonstrating a robust covalent attachment of intact clusters to the graphene surface. Auf dem Präsentierteller: Graphen wurde chemisch modifiziert und mit Au9‐Clustern funktionalisiert. Mithilfe von aberrationskorrigierter Transmissionselektronenmikroskopie konnten dann einzelne Cluster einschließlich ihrer Drehbewegung direkt beobachtet und mit einem simulierten Bild korreliert werden.
