The practical application of mechanoluminescent luminophores has been severely limited by random crystal collapse because it would break down the quantitative relationship between pressure and brightness. In this issue of Matter, Li and co-workers designed a pure organic mechanoluminescent material, tPE-2-Th, by taking advantage of thiophene rings, which endow the molecule with a new equilibrium of orderly molecular arrangement upon force stimuli. tPE-2-Th demonstrates an unusual stable quantitative relationship between pressure and emission intensity. This enables the development of various flexible and wearable devices, which assist information conversion and storage for encrypted communication; sense external force changes for patient care; and detect weak forces such as the human heartbeat for health monitoring.

机械发光的荧光团的实际应用受到随机晶体塌陷的严重限制，因为它将破坏压力和亮度之间的定量关系。在这个问题上物Li和他的同事们通过利用噻吩环设计了纯有机机械发光材料tPE-2-Th，该环使分子在受力刺激时具有新的平衡的分子排列平衡。tPE-2-Th显示出压力和发射强度之间异常稳定的定量关系。这使得能够开发各种灵活且可穿戴的设备，这些设备有助于信息转换和存储以进行加密通信。感知外力变化以进行患者护理；并检测诸如人类心跳等微弱的力量进行健康监测。
