Ionic fluorophores are powerful tools for the study of environmental science and bio‐imaging. However, traditional ionic dyes usually require long synthetic steps and suffer from a quenching effect caused by aggregation. A water‐soluble ionic aggregation‐induced emission luminogen called DBTA is presented, which is readily accessed by a one‐step reaction. The switchable emission manipulated by hydrogen bonding provided solid evidence for the restriction of intramolecular motions as the mechanism of aggregation‐induced emission. DBTA can not only differentiate solvents with different H‐bond donor acidities but also capable of wash‐free imaging in living HeLa cells and fish larva.

具有氢键切换发射和免洗成像能力的易于接近的离子聚集诱导的发射发光剂

离子荧光团是用于环境科学和生物成像研究的强大工具。但是，传统的离子染料通常需要很长的合成步骤，并且会因聚集而产生猝灭作用。介绍了一种水溶性离子聚集诱导的发光剂，称为DBTA，可通过一步反应轻松获得。通过氢键操纵的可转换发射为分子内运动的限制提供了有力的证据，这是聚集诱导发射的机制。DBTA不仅可以区分具有不同H键供体酸度的溶剂，而且还可以在活的HeLa细胞和鱼幼体中进行免洗成像。
