Preparation and characterization of 1⊃S12. a Schematic representation of the transformation from two S6 clusters into a S12 cluster within matrix 1 upon light irradiation and b the proposed intermediate. c 1H NMR spectra (500 MHz, D2O, room temperature) of 1⊃S12 (red line) and 1⊃(S6)2 (gray line). Raman spectra (He−Ne laser, λ ex = 632.8 nm, room temperature) of d 1, e 1⊃(S6)2, and f 1⊃S12. g ESI-TOF MS spectrum (H2O) of 1⊃S12. h Optimized structure of 1ʹ⊃S12 (R = −OCH3): cylindrical and space-filling representation (left) and ball-and-stick representation (right)
