Diazocines on Molecular Platforms (Eur. J. Org. Chem. 25/2014)
The cover picture shows an artistic view of paramecia with artificial cilia. Cilia were probably the first strategy towards directed motion in evolutionary biology, emerging more than a billion years ago. Tremendous developments in dynamic supramolecular chemistry notwithstanding, artificial cilia are still elusive. Chiral, unidirectional molecular switches mounted on surfaces are the prerequisite for inducing cilia-driven directed motion. The article by R. Herges et al. on p. 5456 ff outlines how simple azobenzenes are transformed into chiral switches equipped with a molecular platform to mount them on gold surfaces.
