Gan, Zibao Chen, Jishi Liao, Lingwen Zhang, Hongwen Wu, Zhikun Surface Single-Atom Tailoring of a Gold Nanoparticle Surface single-atom tailoring of a gold nanoparticle, that is, adding, removing, or replacing one surface atom on a structure-resolved nanoparticle in a controlled manner, is very exciting yet challenging and has not been hitherto achieved. Herein we report the first realization of the introduction of a single sulfur atom onto the surface of the structure-unraveled Au<sub>60</sub>S<sub>6</sub>(SCH<sub>2</sub>Ph)<sub>36</sub> nanoparticle. Single-crystal X-ray crystallography reveals that the as-obtained nanoparticle consists of one Au<sub>17</sub> kernel protected by one Au<sub>20</sub>S<sub>3</sub>(SCH<sub>2</sub>Ph)<sub>18</sub> and one unprecedented Au<sub>23</sub>S<sub>4</sub>(SCH<sub>2</sub>Ph)<sub>18</sub> motif with the introduced sulfur atom included as a tetrahedral-coordinated μ<sub>4</sub>-S. The introduced sulfur leads to the changes of both internal structure and crystallographic arrangement. Unlike the case of 6HLH arrangement in Au<sub>60</sub>S<sub>6</sub>(SCH<sub>2</sub>Ph)<sub>36</sub> crystals, the “ABAB” arrangement in Au<sub>60</sub>S<sub>7</sub>(SCH<sub>2</sub>Ph)<sub>36</sub> crystals enhances the solid photoluminescence of amorphous Au<sub>60</sub>S<sub>7</sub>(SCH<sub>2</sub>Ph)<sub>36</sub> and brings a slight redshift of the maximum emission. The extensive near-infrared emission provides Au<sub>60</sub>S<sub>7</sub>(SCH<sub>2</sub>Ph)<sub>36</sub> potential applications in some fields such as anticounterfeiting, imaging, etc. ABAB;6 HLH arrangement;60 S 6;20 S 3;nanoparticle;60 S 7;Single-crystal X-ray crystallography;tetrahedral-coordinated μ 4;Gold Nanoparticle Surface single-atom;Surface Single-Atom Tailoring;SCH 2 Ph;sulfur atom;36 crystals;23 S 4 2017-12-19
