Abstract

Multistimuli-responsive room-temperature phosphorescence (RTP) materials have attracted significant attention for their broad application prospects, especially in the fields of anticounterfeiting, sensors, data storage, etc. However, there is still a lack of detailed information on structural changes under various stimuli, hindering a comprehensive understanding of the dynamic relationship between molecular/aggregated structure and RTP property. Herein, taking temperature and acid as external stimuli, variations in the RTP characteristics can be observed in terms of the lifetime and color scales. Moreover, the detailed variations can be controlled by the dynamic regulation of electrostatic interactions between RTP units and the pyridine core, which can be further detected by the corresponding crystal structures under any conditions. The dynamic one-to-one correspondence between molecular/aggregated structure and RTP property has been established, which can prompt the development of multistimuli-responsive materials by deep understanding of the internal mechanism of dynamic RTP property.

多刺激响应室温磷光：可调节的静电相互作用和相应的精确分子堆积

多瞬态响应室温磷光（RTP）材料因其广阔的应用前景而备受关注，尤其是在防伪、传感器、数据存储等领域。然而，目前仍缺乏各种刺激下结构变化的详细信息，这阻碍了对分子/聚集结构与 RTP 性能之间动态关系的全面了解。在此，以温度和酸作为外部刺激，可以观察到 RTP 特性在寿命和色度方面的变化。此外，RTP 单元与吡啶核心之间的静电相互作用可通过动态调节来控制细节变化，而在任何条件下，相应的晶体结构都能进一步检测到这些变化。分子/聚集结构与 RTP 特性之间建立了一一对应的动态关系，通过深入了解 RTP 动态特性的内在机理，可促进多刺激响应材料的开发。
