Let's do the twist! Molecular crystals of a diarylethene derivative exhibit photoreversible twisting upon irradiation with UV and visible light. The left‐handed and right‐handed helix formation is ascribed to the contraction of the crystal in a diagonal direction, depending on which face is irradiated with UV light.
