The 16e square-planar bis-thiolato-Au(iii) complexes [AuIII (1,2-dicarba- closo -dodecarborane-1,2-dithiolato)2 ][NBu4 ] (Au-1) and [AuIII (4-methyl-1,2-benzenedithiolato)2 ][NBu4 ] (Au-2) have been synthesized and fully characterized. Au-1 and Au-2 were encapsulated in the symmetrical triblock copolymer poloxamer (Pluronic®) P123 containing blocks of poly(ethylene oxide) and poly(propylene oxide), giving micelles AuMs-1 and AuMs-2. High electron flux in scanning transmission electron microscopy (STEM) was used to generate single gold atoms and gold nanocrystals on B/S-doped graphitic surfaces, or S-doped amorphous carbon surfaces from AuMs-1 and AuMs-2, respectively...
