A Synthetic illustration of the desired Ag6 clusters. Colour codes: S, orange; Ag, blue; N, blue; and C, grey. H atoms are omitted for clarity. B Positive mode ESI‒MS spectra of S-Ag6 dissolved in DMF. Insets: Enlarged portion of the ESI‒MS exhibiting the measured (green line) and simulated (red line) isotopic distribution patterns in the m/z range of 1100–2500 with a charge state of + 1. The dominant peak for S-Ag6 can be assigned to [S-Ag6(S2C6H10N)5]+ (m/z = 1448.6220). C Normalised absorption and emission spectra of S-Ag6 (λex = 370 nm) in DCM solution. (Inset: image of S-Ag6 under UV light in DCM at room temperature). D PXRD patterns of simulated and as-prepared crystals of S-Ag6. E CD spectra of (S/R)-Ag6 in DCM solution. F CPL spectra of (S/R)-Ag6 in DCM solution (λex = 370 nm). G glum curves of (S/R)-Ag6 in DCM solution.
