The cover picture shows the supramolecular tetramer that exists as a repeating motif in crystals of the crown ether quinoxaline derivative whose synthesis is shown on the left‐hand side of the figure. As illustrated on the right‐hand side of the graphic, a water molecule, held in place by hydrogen bonds, is bound between each of the two layers that make up the tetramer. These layers are, in turn, made up of two molecules of crown ether functionalized quinoxaline. For more on the self‐assembly properties of this and related quinoxaline species, as well as a discussion of their anion and cation binding properties see the article by J. L. Sessler et al. on p. 3768 ff. We thank Mr. Gheorghe (“Dan”) Pantos for his help in generating this cover illustration.
