Fig. 3: An interconversion mechanism for structural analysis of Au138(SR)48.

a Highly symmetrical [Au–S–Au–S–Au]2 moiety supporting the dynamic behaviors of aromatic rings. Color labels: Au, green and orange; S, yellow; C, red, blue, and gray; H, white. b A schematic representation of the interconversion process between two enantiomers of Au138(SR)48. c Variable-temperature ¹H-NMR spectra covering both aromatic and aliphatic regions. Pink dashed lines highlight the migration of aromatic proton peaks influenced by π–π stacking interactions. Black dashed lines illustrate the configurational dynamics in methyl groups.
