AI Technical Summary
The lack of silver nanoclusters constructed using polyoxometalates with classic saturated Keggin configuration as anionic templates in the existing technology leads to a complex and unstable assembly process for silver nanoclusters.
Using saturated Keggin-configured polyoxometalates soluble in organic phases as anionic templates, Keggin-configured BW12@Ag48 silver nanoclusters were prepared. Through the core-shell structure of [BW12O40]5- core and Ag48 shell, combined with the selective coordination of CyhS- and p-TOS- ligands, stable silver nanoclusters were formed.
BW12@Ag48 silver nanoclusters with high stability and symmetry were successfully prepared, which enhanced the structural stability and silver ion aggregation ability of silver nanoclusters and provided more diverse structural and application prospects.
