Herein, A single\u2010component azobenzene crystal is reported to exhibit an abrupt and reversible stretching of over 8% along its long axis, driven by a thermally induced single\u2010crystal\u2010to\u2010single\u2010crystal phase transition. Single\u2010crystal X\u2010ray diffraction revealed a significant change in molecular packing distance along the long axis accompanied by the reorientation of CH\u2013\u03c0 interactions, leading to large macroscopic stretching\/shrinking. Furthermore, visible light (435\u00a0nm) induced rapid, localized, and reversible stretching of the crystal via the photothermal effect, enabling the remote control of microparticle motion. This study reveals a rare combination of large anisotropic deformation, reversibility, and light responsiveness in a single\u2010component organic crystal, offering a new molecular platform for advancing micro\u2010energy conversion and soft robotics.<\/jats:p>","DOI":"10.1002\/advs.202512603","type":"journal-article","created":{"date-parts":[[2025,10,14]],"date-time":"2025-10-14T12:28:13Z","timestamp":1760444893000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Abrupt
