Molecular crystal nanowires composed of an anthracene‐9‐(1,3‐butadiene) derivative exhibit a rapid transition from straight to highly coiled structures when exposed to a pulse of visible light. The curling does not depend on the direction of light illumination and occurs for nanowires composed of either the E or Z isomer. The shape change is driven by an E ⇄ Z photoisomerization reaction that generates a mixture of isomers within a single nanowire.
