Synthesis of atom‐precise alloy nanoclusters with uniform composition is challenging when the alloying atoms are similar in size (for example, Ag and Au). A galvanic exchange strategy has been devised to produce a compositionally uniform [Ag24Au(SR)18]− cluster (SR: thiolate) using a pure [Ag25(SR)18]− cluster as a template. Conversely, the direct synthesis of Ag24Au cluster leads to a mixture of...
Die Synthese atompräziser Legierungs‐Nanocluster mit gleichförmiger Zusammensetzung ist anspruchsvoll, wenn die legierenden Atome ähnliche Größe haben. O. M. Bakr et al. beschreiben in der Zuschrift auf S. 934 ff., wie es ihnen mithilfe von galvanischem Austausch gelang, das zentrale Silberatom in [Ag25(SR)18]− selektiv durch ein Goldatom zu ersetzen. Die verbesserten optischen Eigenschaften und die...
