陕西师范大学房喻团队报道了双发色荧光探针在多刺激传感和视觉识别中的作用。相关研究成果发表在2025年1月16日出版的《中国化学》。

用于监测各种环境参数的多功能荧光探针的进步至关重要。

该文中，研究人员设计了通过整合具有独特特征的官能团，来响应多种刺激的双发色团荧光探针DBT。值得注意的是，探针DBT在特定条件下表现出明显的双峰发射，其荧光在红色和蓝色之间移动，以响应溶剂组成、湿度水平和温度变化的变化。

值得注意的是，DBT有助于区分和视觉识别八种溶剂，并能定量检测有机溶剂中的痕量水含量。此外，它还对汽油进行视觉检测。

研究发现预示着能够响应多种刺激的单分子荧光材料的发展，为在各种应用中同时检测和区分多种刺激铺平了道路。

Abstract: The advancement of multifunctional fluorescent probes for monitoring diverse environmental parameters is of paramount importance. In this study, we engineered dual-chromophore fluorescent probe, DBT, that responds to multiple stimuli by integrating functional groups with unique characteristics. Notably, the probe DBT exhibits pronounced bimodal emission under specific conditions, with its fluorescence shifting between red and blue in response to alterations in solvent composition, humidity levels, and temperature variations. Significantly, DBT facilitates the differentiation and visual identification of eight solvents, and permits the quantitative detection of trace water content in organic solvents. Additionally, it allows for the visual detection of gasoline. These findings herald the development of single-molecule fluorescent materials capable of responding to multiple stimulus, paving the way for simultaneous multi-stimuli detection and discrimination in various applications.
