Abstract:
Ag nanoclusters have received increasing attention due to their atomically precise and diverse structures and intriguing optical properties. Nevertheless, the inherent instability of Ag nanoclusters has seriously hindered their practical application. In this work, for the first time, Ag clusters are collaboratively protected by hydrophobic Ti‐oxo clusters and alkyne ligands. Initially, a pyramidal Ag 5 cluster terminated with t BuC≡C − and CH 3 CN was inserted into the cavity of a Ti 8 ‐oxo nanoring to form Ag 5 @Ti 8 . To overcome the instability of acetonitrile‐terminated silver site, such two Ag 5 @Ti 8 clusters could sandwich an Ag 4 unit to form Ag 14 ‐nanorod@Ti 16 ‐oxo‐nanoring (Ag 14 @Ti 16 ), which is peripherally protected by fluorophenyl groups and alkyne caps. This threefold protected (hydrophobic fluorinated organic layer, Ti‐O shell, and terminal alkyne ligands) Ag 14 @Ti 16 exhibits superhydrophobicity and excellent ambient stability, endowing it with solid‐state optical limiting characteristics.
