a 1H NMR spectra of (i) the ligand (1), (ii) [Ag512]∙[OTf]5 (Ag5L2) and (iii) [Hg512]∙[OTf]10 (Hg5L2) in 5:95 (v/v) CD3CN/CDCl3. b 1H NMR spectra of (i) the ligand (1), (ii) [Ag512]∙[OTf]5 (Ag5L2) and (iii) [Hg512]∙[OTf]10 (Hg5L2) in CDCl2CDCl2. The formations of cages give significant upfield shifts of those protons located in the inner cavity, including Ha, Hb and Hg, and a split of the Hi signals, compared to the ligand 1.
