Cover Picture (Angew. Chem. Int. Ed. 8/1999)

38_08/1999The cover picture shows the assembly of a pseudorotaxane at the surface of a nanocrystal. A gold nanocrystal stabilized by a chemisorbed monolayer of dodecanethiol covalently linked to dibenzo[24]crown-8 recognizes and binds selectively dibenzylammonium cations in solution to form pseudorotaxanes in which 86% A of the crown units are complexed with a cation. The similarity to the binding of a drug molecule by the receptor sites on the surface of a cell is noted. Further details on this heterosupramolecular chemistry is reported by D. Fitzmaurice et al. on pages 1147 ff.
