Materials that convert heat into bulk mechanical motion are promising candidates for actuators, sensors, and memory devices. Dicyanomethylenated acridone showed crystal jumping upon heating. Variable‐temperature X‐ray analyses revealed that the collective fluctuation/flipping motion of the molecule‐induced crystal jumping. This motion is represented as a bouncing disc‐ball toy in the cover picture. More information can be found in the Full Paper by T. Takeda and T. Akutagawa on page 7763 ff.
