Partial ¹H NMR spectra of capsular assemblies. (a) Resorcinarene 1 (2 mM) in chloroform; the formation of hexamer 1₆ occurs with 6–8 encapsulated solvent molecules. (b) Two micromolar 2 in chloroform yields the cylindrical capsule 2₂ with 3 surrounded solvent molecules. (c) Mixing 2 (2 mM) with 1 (2.5 mM) results in the formation of hybrid capsule 1.2; the original homomeric capsules are also present. (d) Tennis ball 3₂ (2 mM) in chloroform containing dissolved atmospheric gases. (e) Mixing of 2₂ (2 mM) and 3₂ (2 mM) gives the new hybrid capsule 2.3. Complete NMR peaks assignment of 2.3 are given in the SI.
