Fig. 6: Inner modification and guest encapsulation within the [6]catenane framework.
a Estimated model of the side chain positions at the Z residue using ligand 5K as an example. Lys side chains are highlighted in stick representation and the remaining [6]catenane framework (surface representation) is a cross-sectional view. Note that all of the Cbz protecting groups and some of the Lys side chains have been omitted for clarity. b Geometry-optimised structure of encapsulation complex [Ag24(9)24]24+•(G)2. The [6]catenane framework, all the side chains of Cit residues, and G are shown in surface, stick, and space-filling representations, respectively. The chemical structure of G is also shown.
