Due to the significant relationships between structure and properties, controlled construction of atomically precise metal clusters presents both a formidable challenge great importance. The innovative synthesis well-defined silver nanoclusters with near-infrared II (NIR-II) luminescent properties may inspire further exploration functional for bioimaging applications. In this study, we employed multidentate chelating nitrogen ligand 3,5-di(2-pyridyl)pyrazole (Hbpypz) construct three unprecedented nanoclusters: [Ag27(bpypz)14]3+ (Ag27), [Ag62(bpypz)18]6+ (Ag62), [Ag91(bpypz)24]5+ (Ag91). Single-crystal X-ray analysis indicated that these cluster structures stem from Ag13 units, exhibiting cluster-of-cluster configurations. By modulating stoichiometry centers, achieved size growth reversible cluster-to-cluster conversions among nanoclusters. Notably, Ag27 nanocluster exhibits an interesting thermally activated delayed fluorescence (TADF) based luminescence in second region demonstrates high catalytic efficiency oxidative coupling benzylamines via singlet oxygen (1O2) oxidation mechanism.

Chiral gold nanomaterials have promising applications in biomedicine, catalysis, optics and other fields. However, the complexity of their chiral sources has led to many challenges terms functional design controlled synthesis. In this paper, we systematically review development history Au nanomaterials; deeply analyze synthesis strategy, construction mechanism, performance optimization pathway; discuss formation mechanism light progress cutting-edge research look into future direction development. The aim is provide theoretical methodological support for controllable nanomaterials.
