Evolution from superatomic Au₂₄Ag₂₀ monomers into molecular-like Au₄₃Ag₃₈ dimeric nanoclusters.

ABSTRACT: Hierarchical assembly of nanoparticles has been attracting wide interest, as advanced functionalities can be achieved. However, the ability to manipulate structural evolution of artificial nanoparticles into assemblies with atomic precision has been largely unsuccessful. Here we report the evolution from monomeric Au₂₄Au₂₀ into dimeric Au₄₃Ag₃₈ nanoclusters: Au₄₃Ag₃₈ inherits the kernel frameworks from parent Au₂₄Ag₂₀ but exhibits distinct surface motifs; Au₂₄Ag₂₀ is racemic, while Au₄₃Ag₃₈ is mesomeric. Importantly, the evolution from monomers to dimers opens up exciting opportunities exploring currently unknown properties of monomeric and dimeric alloy nanoc
