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.

蒽-9-硫代甲酰胺的现成热显着性


我们证明了蒽-9-硫代甲酰胺的热凸行为。冷却后，晶体材料会自发破裂并跳跃。强的各向异性热膨胀先于热凸性，氢键和较弱的层间相互作用的结合提供了宏观响应。通过结合来自不同类别热凸固体的结构部分并使用尚未充分探索的超分子合成子，获得了动态多功能材料。
