Adaptive crystals have attracted significant attention from solid-state chemists and crystal engineers for their promising applications in memories, capacitors, sensors, actuators. Among them, thermosalient are particularly favored thanks to efficient energy conversions rapid responses. However, the mechanisms mechanical responses of remain largely unclear. Herein we demonstrate that effects molecular could be driven by thermoelastic twisting behaviors. The crystal, based on a model compound with rigid dibenzothiophene sulfone planes flexible ethoxy chains, can spontaneously self-heal fractures. Upon heating, undergoes remarkable behaviors distinctive left- or right-handed twisting. This converts thermal into elastic potential energy, which is further released as kinetic upon untwisting drive jump. Our demonstration twisting–induced jumping offers different perspective origins provide inspiration future engineering application dynamic crystals.

The cornerstones of the advancement flexible optoelectronics are design, preparation, and utilization novel materials with favorable mechanical advanced optoelectronic properties. Molecular crystalline have emerged as a class underexplored yet promising due to reduced grain boundaries defects anticipated provide enhanced photoelectric characteristics. An inherent drawback that has precluded wider implementation molecular crystals thus far, however, been their brittleness, which renders them incapable ensuring compliance required for even simple elastic or plastic deformation device. It is perplexing despite plethora reports in meantime become available underpinning flexibility crystals, "discovery" elastically plastically deformable remains limited cases serendipitous laborious trial-and-error approaches, situation calls systematic thorough assessment these properties correlation structure. This review provides comprehensive concise overview current understanding origins crystal flexibility, working mechanisms deformations such bending behaviors, insights into examples specifically concerning photoelectronic changes occur deformed crystals. We hope this summary will reference future experimental computational efforts aimed towards improving behavior properties, ultimately intending advance technology.
