    • An apohost is defined as the state of the host component from the crystallized host 1-AcOH after the removal of the guest.

    • The average size of the crystals including a standard deviation was ∼(250 ± 90)μM × (3 ± 1)μM. The smallest dimension of the crystal could not be accurately measured from the SEM image.

    • The average size of unground apohost 1 crystals was estimated by SEM as ∼(260 ± 100) μM × (3 ± 2) μM.

    • This experiment was also reported in our earlier J. Am. Chem. Soc. communication, ref 6. There appears to have been an impurity present in the earlier study in both the apohost 1 and filled host 1·AcOH that was not observed in these experiments.

    • The distances were calculated from the X-ray structure, CCDC reference number 228322, using the intemuclear distances - the sum of van der Waals radii of the atoms involved. The van der Waals radii used to define the surfaces were H = 1.20 Å, C = 1.70 Å.

    • Table 2 reports the average binding stoichiometry for a minimum of three absorption-desorption experiments. The exact number of binding experiments measured was 71 for acetic acid, 8 for propanoic acid, 8 for butanoic acid, 3 for pentanoic acid, and 4 for acrylic acid.
