From: Self-assembly of chiroptical ionic co-crystals from silver nanoclusters and organic macrocycles

UV-vis-NIR absorption spectra of a, Ag25(SR)18−PPh4+, b, Ag25(SR)18−TATA3C3+, and c, Ag25(SR)18−TATA3C7+ in CH2Cl2 solution at different time points. Spectra in b and c are offset vertically for clarity.
