摘要
能够发生光扭曲和光弯曲的超弹性有机晶体的发现是光响应材料领域的一大进步。这项研究的重点是三氟甲基取代酰腙衍生物（又称 TBMP）晶体的合成和表征。这些晶体在沿其（010）结晶平面受到机械力时表现出显著的超弹性，而沿其（001）平面则有断裂倾向。单晶分析表明，氢键，尤其是C-H--F、C-H--O和C-H--N相互作用，是晶体具有超弹性特性的关键。此外，在紫外线照射和加热条件下，TBMP 分子会发生 E ↔ Z 的可逆异构化，从而导致晶体的光机械（扭曲或弯曲）和热恢复行为。由于其优异的性能，这些晶体在机械臂技术中具有巨大的应用潜力。
Superelastic and Photomechanical Behavior of Acylhydrazone Derivative Crystals
The discovery of superelastic organic crystals capable of phototwisting and photobending represents a significant advance in the field of light-responsive materials. This research focused on the synthesis and characterization of crystals derived from trifluoromethyl-substituted acylhydrazone derivatives, known as TBMP. These crystals exhibited remarkable superelasticity when subjected to mechanical forces along their (010) crystallographic plane while showing a tendency to fracture along the (001) plane. Single-crystal analysis revealed that hydrogen bonds, especially C–H···F, C–H···O, and C–H···N interactions, are crucial in providing the crystals with superelastic properties. In addition, reversible E ↔ Z isomerization of TBMP molecules occurred under UV irradiation and heating, resulting in photomechanical (twisting or bending) and thermal recovery behavior of the crystals. Due to their exceptional properties, these crystals possess significant potential for application in robotic arm technology.
