We demonstrate thermosalient behavior in anthracene-9-thiocarboxamide. Upon cooling, the crystalline material spontaneously fractures and jumps. Strong anisotropic thermal expansion precedes thermosalience, and the combination of hydrogen bonds and weaker interlayer interactions affords the macroscopic response. By incorporating structural moieties from different classes of thermosalient solids and using an underexplored supramolecular synthon, a dynamic, multi-functional material is achieved.
我们展示了蒽-9-硫代甲酰胺中的热突出行为。冷却时，晶体材料会自发断裂并跳跃。热突出之前存在强烈的各向异性热膨胀，氢键和较弱的层间相互作用共同导致了宏观响应。通过引入不同类型热突出固体的结构部分，并使用一种未充分探索的超分子合成子，获得了一种动态、多功能材料。
