Mechanoluminescence (ML) is the production of light from materials in response to the external stimulus of mechanical action. For organic compounds, the production of ML is tightly associated with fracture and plastic deformation of materials with piezoelectric effect in crystal lattice, and the ML property is highly dependent on the molecular packing mode, spatial conformation, and intermolecular interaction in the solid state. In the past few years, our group focused on the molecular design of pure organic ML compounds, with an attempt to discover different features of ML in pursuing the inherent emission mechanism and potential practical applications. We successfully found polymorph-dependent ML, ML with a phosphorescent property, conformation-dependent ML, ML with odd–even effect, wearable ML devices applied in heartbeat and pressure detection, etc. In this Perspective, we aim to deepen the understanding of ML and provide some guidance for the molecular design of organic light-emitting materials through the combination of our contributions.

纯有机机械发光材料研究进展

机械发光 (ML) 是材料响应机械作用的外部刺激而产生的光。对于有机化合物，ML的产生与晶格中具有压电效应的材料的断裂和塑性变形密切相关，ML性质高度依赖于分子堆积方式、空间构象和固态分子间的相互作用。在过去的几年中，我们小组专注于纯有机ML化合物的分子设计，试图发现ML的不同特征，以追求其固有的发射机制和潜在的实际应用。我们成功地发现了多晶型依赖性 ML，具有磷光特性的 ML，构象依赖性 ML，具有奇偶效应的 ML，可穿戴式 ML 设备应用于心跳和压力检测，
