51_04i/2012Inside Cover: Light-Driven Molecular-Crystal Actuators: Rapid and Reversible Bending of Rodlike Mixed Crystals of Diarylethene Derivatives (Angew. Chem. Int. Ed. 4/2012)

Light-driven actuators can be potentially used in various micro- and nanomechanical applications. In their Communication on page 901 ff., M. Irie and co-workers describe the preparation of robust molecular-crystal actuators with interesting mechanical properties. Two-component mixed crystals of photochromic diaryl ethenes exhibit rapid, reversible, and fatigue-resistant bending upon photoirradiation and carry out mechanical work, such as lifting weights and rotating gears.
