Abstract: We reported the synthesis of Au130(SPh-Br)50(Br-Ph-SH=4-bromothiophenol) nanocluster with high purity and high yield via "size focusing" and "ligand exchange" processes. The time of synthetic process was significantly reduced compared with previous synthetic routine. Au130(SPh-Br)50 was determined by UV-Vis absorption spectroscopy and matrix-assisted laser desorption ionization(MALDI) mass spectroscopy. Thermo-gravimetric analysis (TGA) and size-exclusion chromatogram(SEC) analyses confirmed the purity of Au130(SPh-Br)50. The yield of gold nanoclusters was 20% (based on HAuCl4).
