We report a new synthetic protocol of Au99(SPh)42 nanoclusters with moderate efficiency (∼15% yield based on HAuCl4), 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.
