合成了一系列外金原子上带有两个富苄基配体的[core + exo]型Au8纳米簇（NCs），具有良好的光稳定性和化学稳定性。此外，富苄基配体增强了Au NCs的发射强度。富苄基配体修饰的Au8纳米碳纳米管作为细胞显像剂具有较好的性能，这意味着富苄基配体在调节金纳米簇的光物理性质方面具有潜在的用途。
A series of [core + exo]-type Au8 nanoclusters (NCs) bearing two benzyl-rich ligands on the exo gold atoms were synthesized, which exhibit significant photostability and chemical stability. Furthermore, the benzyl-rich ligands enhance the emission intensity of Au NCs. The better performance of the benzyl-rich ligand- modified Au8 NCs as cell imaging agents implies potential utility of benzyl-rich ligands for modulating the photophysical properties of gold nanoclusters.
