In this paper, a new 'turn-on' fluorescence probe for the rapid, sensitive, and visual detection of hypochlorite is reported. The push-pull type trianiline-tricyanofuran-based fluorescent probe was prepared using a condensation reaction between tricyanofuran and the thiophene-trianiline derivative that had high quantum yields and showed aggregation-induced emission enhanced properties. Upon exposure to hypochlorite, prominent fluorescence enhancement of the probe was observed via the release of the fluorophore from the probe. The probe showed a ratiometric absorption change at 315 nm and 575 nm. Importantly, the probe showed an excellent detection limit for hypochlorite at 1.2 × 10-7 M in solution and it was successfully applied for monitoring hypochlorite in waste water by test strip. This work reports a new fluorescence analytical sensing method for hypochlorite that has potential practical value in environmental monitoring and biological discrimination.

快速直观地检测AIE增强型荧光探针中的次氯酸盐。

在本文中，报道了一种用于快速，灵敏和视觉检测次氯酸盐的新型“开启”荧光探针。推挽型三苯胺-三氰呋喃基荧光探针是通过三氰呋喃与噻吩-三苯胺衍生物之间的缩合反应制备的，该缩合反应具有高的量子产率并显示出聚集诱导的发射增强性质。暴露于次氯酸盐后，通过从探针释放荧光团，观察到了探针显着的荧光增强。探针显示在315 nm和575 nm处的比例吸收变化。重要的是，该探针对溶液中次氯酸盐的检测极限极佳，为1.2×10-7 M，并且已成功通过试纸条成功用于监测废水中的次氯酸盐。
