46_1-2/2007Cover Picture: Inclusion of Cavitands and Calix[4]arenes into a Metallobridged para-(1H-Imidazo[4,5-f][3,8]phenanthrolin-2-yl)-Expanded Calix[4]arene (Angew. Chem. Int. Ed. 1-2/2007)

Hunter and hunted is not only a principle of nature but is also found in host–guest systems. J. de Mendoza and co-workers describe in their Communication on page 198 ff. how a host molecule (a small calix[4]arene or cavitand) can itself become the “prey” for a larger host (a metallocavitand made from a calix[4]arene with [3,8]phenanthroline subunits linked through Re atoms). The cover picture shows the complexation of a cavitand (by P. Ballester) superimposed on an underwater picture at Cap Andritxol, Mallorca (by E. Botana).

In their Communication on page 194 ff., J. K. M. Sanders and co-workers show that the helical chirality of nanotubes formed by amino acid derivatives of naphthalenediimide is determined by the constituent amino acid but is independent of the nature of the side chains.
