Size conversion from Au23 to Au25 nanoclusters. a Schematic illustration of size-conversion reaction from [Au23(SR)16]− to [Au25(SR)18]− (yellow, Au; wine, S), where SR denotes thiolate ligand. b,c Ultraviolet-visible absorption and d,e electrospray ionization mass spectra of b,d [Au23(SR)16]− and c,e [Au25(SR)18]−. The crystal structures of [Au23(SR)16]− and [Au25(SR)18]− are drawn according to the reported Au23S1656 and Au25S1813 skeletons, where all hydrocarbon tails are omitted for clarity. Insets in b,c are digital photos of the corresponding cluster solution. The magenta lines in d,e show simulated isotope patterns of the labeled cluster formulas, which match perfectly with the corresponding experimental data
