Cover Picture: Mechanically Interlocked Molecules Assembled by π–π Recognition (ChemPlusChem 3/2012)
The cover picture shows the construction of mechanically interlocked molecules comprising aromatic π–π stacking interactions which have attracted a vast amount of interest during the past decade. The template-directed synthetic protocols and recognition motifs including donor-acceptor, neutral, and radical interactions are discussed, as well as the potential applications of the resulting mechanically interlocked molecules. Further details can be found in the Review by J. F. Stoddart et al. on page 159 ff.
