A fluorescent probe for gold ion, Au(III), is developed based on Au(III)-induced disaggregation of AIEgen for the first time. Although many contributions have been made to develop fluorescent probes for sensing Au(III), many of them were faced with limitations such as complex mechanism, slow response time, and sophisticated synthetic procedure. In current work, an AIEgen disaggregation based fluorescent probe for Au(III) was simply prepared, and it showed high sensitivity and selectivity with fast response time toward Au(III). Moreover, probe can be utilized to monitor Au(III) in cells as well as paper-based strip for detecting of Au(III).

首次基于Au（III）诱导的AIEgen分解，开发了一种用于金离子的荧光探针Au（III）。尽管已经为开发用于感测Au（III）的荧光探针做出了许多贡献，但许多探针都面临着局限性，例如复杂的机制，响应时间慢和合成方法复杂。在当前工作中，仅制备了基于AIEgen分解的Au（III）荧光探针，该探针显示出高灵敏度和选择性，并且对Au（III）的响应时间短。此外，探针可用于监测细胞中的Au（III）以及用于检测Au（III）的纸条。
