    • note
    • It is interesting to notice that all the substrates belonging to the first subset possess a poorly hydrophobic, conformationally flexible ancillary chain able to donate/accept two hydrogen bonds simultaneously. On the other hand, the substrates belonging to the second subset have ancillary chains unable to form multiple hydrogen bonds for various reasons: 4 and 5 possess only one donor/acceptor site, whereas the ammonium cationic head group of 6-8, presumably, is too strongly solvated. Moreover, the occurrence of particularly effective hydrophobic interactions between the CD cavity the ancillary chains of 7 and 8 is likely.

    • Of course, the binding equilibrium is per se a dynamic process. Therefore, it is implicit that the solvent swap process is 'fast' in the lifetime scale of the inclusion complex.
