a Raman spectra of 3·6Cl before and after I2 adsorption. b Cl 2p XPS spectra of pristine 3·6Cl and I2@3·6Cl. c Partial 1H NMR spectra of 3·6X (X = Cl−, Br−, I−, PF6−) (black line) and corresponding samples with 6 equiv of I2 (red line) in DMSO−d6. Chemical shifts of imidazolium proton Hc induced by addition of I2 are indicated by black dashed lines.
