Article Synopsis
- The dynamic crystalline material displays exceptional mechanical resilience, allowing it to undergo significant elastic deformation (up to 2.6%) and recover its original shape without damage, showcasing excellent elasticity and the ability to twist and bend.
- Its thermal mode involves precise control over phase boundaries based on temperature, leading to various motions such as shear deformation, with different effects depending on the alignment of the boundaries (thermomechanical or thermosalient).
- The material can also switch structures in response to light through photochemical processes, enabling rapid bending when exposed to UV light and contributing to its diverse mechanical responses; this is made possible by minor structural changes and weak hydrogen bonds that preserve its long-range order.

Organic molecular crystals have historically been viewed as delicate and fragile materials. However, recent studies have revealed that many organic crystals, especially those with high aspect ratios, can display significant flexibility, elasticity, and shape adaptability. The discovery of mechanical compliance in organic crystals has recently enabled their integration with responsive polymers and other components to create novel hybrid and composite materials.
