%X 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 Au60S6(SCH2Ph)36 nanoparticle. Single-crystal X-ray crystallography reveals
that the as-obtained nanoparticle consists of one Au17 kernel
protected by one Au20S3(SCH2Ph)18 and one unprecedented Au23S4(SCH2Ph)18 motif with the introduced sulfur atom included
as a tetrahedral-coordinated μ4-S. The introduced
sulfur leads to the changes of both internal structure and crystallographic
arrangement. Unlike the case of 6HLH arrangement in Au60S6(SCH2Ph)36 crystals, the “ABAB”
arrangement in Au60S7(SCH2Ph)36 crystals enhances the solid photoluminescence of amorphous
Au60S7(SCH2Ph)36 and brings
a slight redshift of the maximum emission. The extensive near-infrared
emission provides Au60S7(SCH2Ph)36 potential applications in some fields such as anticounterfeiting,
imaging, etc.
