Cover Picture: Self-Assembled Capsules of Unprecedented Shapes (Angew. Chem. Int. Ed. 50/2011)
The self-assembly of banana- and S-shaped structures consisting of nine and eleven subunits, respectively, is reported in the Communication by J. Rebek, Jr. and co-workers on page 12003 ff. Characterization of the bent structures by NMR spectroscopic methods and shape-selective encapsulation experiments showed that the banana-shaped molecular capsule could encapsulate a complementary shaped guest that is not encapsulated in the known cylindrical capsules.
