Formation and characterization of 1⊃(S8)2. a Schematic representation of the encapsulation of two S8 clusters within matrix 1. 1H NMR spectra (500 MHz, D2O, room temperature) of b 1 and c 1⊃(S8)2. d UV-visible spectra (room temperature) of 1 and 1⊃(S8)2 in H2O, and S8 in CH3OH. X-ray crystal structure of 1⊃(S8)2 (host and guest parts): e cylinder and space-filling representation, f ball-and-stick, and g space-filling representations (the peripheral substituents are replaced by hydrogen atoms). h MALDI-TOF MS spectrum of S8. i ESI-TOF MS spectrum (H2O) of 1⊃(S8)2 and the expansion of the [1⊃(S8)2−4•NO3 −]4+ peak
