Abstract:
Structural transformations of nanoclusters provide a platform to tune their properties and understand the fundamental science due to their intimate structure–property correlation. Here, we present an alkynyl ligand-exchange induced growth of atomically precise silver( i ) clusters, which are particularly of interest because of their luminescence response at room temperature. SCXRD and UV-vis map out the growth steps of the cluster from [Ag 32 S 3 (CCBu t ) 23 ] 3+ featuring a pseudo- D 3h concave Ag 32 S 3 to [Ag 45 S 6 (CCPhBr) 32 ] + with a pseudo- O h core–shell Ag 9 S 6 @Ag 24 @Ag 12 , which is driven by a thermodynamic route under the disruption of ligands. To our knowledge, the findings in this work establish the first example of ligand-exchange as a versatile tool for tuning the size and luminescence of semiconductor silver( i ) clusters.
