多重刺激响应有机余辉材料: 设计策略与动态响应机制

Organic afterglow materials have emerged as a research hotspot in the era of intelligent interconnection, due to their multidimensional responsive characteristics. Multi-stimulus-responsive organic afterglow materials can capture diverse environmental signals and achieve synergistic responses across multiple dimensions, enabling highly sensitive and specific integrated intelligent responses. However, their development faces challenges, including compatibility between different stimulus responses, as well as a dynamic balance between afterglow performance and response sensitivity. Recently, through regulation of molecular structures and aggregation states has achieved synergistic integration of multi-stimulus responsiveness with afterglow properties. This review summarizes recent design strategies for small-molecule (single-component/multi-component) and polymeric systems, analyzes the mechanisms underlying stimulus-induced phosphorescence variations, and explores their application potential in information encryption and environmental monitoring. It is hoped that this review can provide new insights and references for the development of intelligent, dynamic sensing afterglow materials.
