Cover Explanation:

The figure on the cover is a Van der Waals radii space-filling image of one of the many diverse reaction products of the polymerizable cyclodextrin derivative synthesis described in the article by Bowen et al. of this issue. This synthesis produced a family (group, ensemble, or collection) of copolymerizable cyclodextrin derivatives having many combinations and permutations; one family member is illustrated here.
