Inside Back Cover: A Small Molecule that Walks Non-Directionally Along a Track Without External Intervention (Angew. Chem. Int. Ed. 22/2012)
Walking along a track is no problem for a small molecule, as described by D. A. Leigh et al. in their Communication on page 5480 ff. The synthetic small molecule walks through successive Michael/retro-Michael reactions and ultimately performs a task, namely quenching the fluorescence of an anthracene group at one end of the track.
