Efficient synthesis of Au 99 (SR) 42 nanoclusters
We report a new synthetic protocol of Au 99 (SPh) 42 nanoclusters with moderate efficiency (∼15% yield based on HAuCl 4 ), via a combination of the ligand-exchange and “size-focusing” processes. The purity of the as-prepared gold nanoclusters is characterized by matrix-assisted laser desorption ioni...

42
nanoclusters with moderate efficiency (∼15% yield based on HAuCl

via
a combination of the ligand-exchange and “size-focusing” processes. The purity of the as-prepared gold nanoclusters is characterized by matrix-assisted laser desorption ionization mass spectrometry and size exclusion chromatography. |
