聚合物作为一种重要的材料, 被广泛应用于工程和医疗等多个领域. 其中, 刚性是聚合物的重要力学性能之一, 其对结构强度、流变行为及玻璃化转变温度等具有关键影响. 因此, 准确测量和表征聚合物的刚性对于材料设计和性能调控至关重要. 传统刚致荧光变色分子在刚性增强时通常表现为轻微蓝移或仅强度发生变化, 导致其灵敏度低, 信号对比度差, 限制了其应用潜力. 近年来研究者们开发了一类新型刚致荧光变色分子, 它们在高刚性环境下呈现独特的刚致红移现象, 并表现出更高的检测灵敏度. 基于此, 系统介绍了几种经典的刚致荧光变色分子的工作机理, 并深入探讨了新型刚致荧光变色分子的设计策略、制备方法及其在各领域的应用前景.

Polymers, as essential materials, have been widely utilized in multiple fields such as engineering and medicine. Among their properties, rigidity stands as a critical mechanical characteristic, which plays a decisive role in structural integrity, rheological behavior, and the glass transition temperature. Therefore, accurately measuring and characterizing polymer rigidity is crucial for material design and performance regulation. Conventional rigidochromic fluorophores typically exhibit either a slight blue-shifted emission or solely intensity variations upon rigidity enhancement, resulting in low sensitivity and poor signal contrast, which limits their application potential. However, in recent years, researchers have discovered a novel class of rigidochromic fluorophores that exhibit a unique rigidity-induced red shift in highly rigid environments, along with enhanced detection sensitivity. Based on this, the working mechanisms of several classical rigidochromic fluorophores are systematically introduced, the design strategies and preparation methods of novel rigidochromic fluorophores, and their potential applications in various fields are explored deeply.
