It is of great significance to design a single probe, which can detect two different types of analytes. Herein, we synthesized the first dual-function fluorescent probe (probe FSQTZ) for the detection of water content and hypochlorite (ClO⁻) under different excitation wavelengths. The probe itself had strong fluorescence in four dry organic solvent, and the increase of water content could cause its fluorescence quenching and fluorescence color change. The probe was especially responsive to water in acetone (LOD = 0.014 wt %), and it can be employed to detect tiny amounts of water in commercial products such as aginomoto, salt, dried jasmine, and dried dates. Meanwhile, probe FSQTZ can selectively detect ClO⁻ in aqueous solution with a remarkable large Stokes shift (168 nm), a rapid response time (within 10 s), an obvious change of color, a wide pH range of response, and it was also applied for imaging ClO⁻ in PC12 cells. Furthermore, the CIE 1931 chromaticity diagram was successfully used to show the accurate color changes of probe.

设计一个可以检测两种不同类型分析物的探针非常重要。在此，我们合成的第一双功能荧光探针（探针FSQTZ）检测的水含量和次氯酸盐（CLO ^- ）下不同的激发波长。探针本身在四种干燥的有机溶剂中具有很强的荧光，并且水含量的增加可能导致其荧光猝灭和荧光颜色变化。该探针对丙酮中的水特别敏感（LOD = 0.014 wt％），可用于检测商品中的少量水，如味之素，盐，茉莉干和枣干。同时，探头FSQTZ可以选择性地检测CLO ^-在具有显着大的斯托克斯频移（168纳米），快速响应时间（10秒内），颜色的明显变化，在宽的pH范围的反应，和它的水溶液也适用于成像CLO ^- PC12细胞。此外，CIE 1931色度图已成功用于显示探头的准确颜色变化。
