    • The guest is rather short to span the two calix[5]arene cavities, and the shielding experienced by the included chain is less effective than that observed with the longer, more tightly bound guest salts.

    • Again, a possible chloride-driven self-assembly of the various capsular complexes is clearly indicated by the presence of mixed assemblies (see Supporting Information).
