From: Asymmetric transformation of achiral gold nanoclusters with negative nonlinear dependence between chiroptical activity and enantiomeric excess

Fig. 4

a, d The asymmetric arrangement of -S-Au-S- and -S-Au-S-Au-S-Au-S- motifs on the surface of the Au13 kernel. b, e The intrinsic chirality of phosphoramidite ligand at the two vertices of the Au13 kernel. c, f The helical arrangement of nanocluster molecules. Color label: Au13 kernel = rose red; -S-Au-S- and -S-Au-S-Au-S-Au-S- staple motifs = cyan; Helical nanocluster molecules = yellow; P = green; N = orange; O = light blue; C = gray. H atoms are omitted for clarity.
