In this article, we present a facile, direct, synthetic approach of preparing monodisperse [Au25(SePh)18]− nanoclusters in high yield. In this synthetic approach, two-phase Brust-Schiffrin method is used. Both PhSeH and NaBH4 should be added drop-wise to the solution of Au (III) at the same time. The formula and molecular purity of [Au25(SePh)18]−TOA+ clusters are characterized by MALDI-TOF mass spectrometry,...
