Abstract: The controlled synthesis of pure Au-25(2-Nap)(18) and Au-36(2-Nap)(24) nanoclusters were achieved via etching 2-(diphenylphosphino)pyridine protected polydispersed Au nanoclusters with a mass of 1 to 3 kDa. Au-25(2-Nap)(18) was obtained at the etching temperature of 80 degrees C, while Au-36(2-Nap)(24) was synthesized at the etching temperature of 50 degrees C. This demonstrates that the simple adjustment of the etching temperatures can realize the controlled synthesis of different atomically precise Au nanoclusters.
