A new reaction-based fluorescent probe 6-cyanonaphthalen-2-yl-2,4- dinitrobenzenesulfonate (probe 1) was designed and synthesized for detection of hydrogen sulfide (H2 S). The addition of H2 S to a solution of probe 1 resulted in a marked fluorescence increased accompanied by a visual color change from colorless to yellow. Importantly, this distinct color response indicates that probe 1 could be used as a visual tool for detection of H2 S. H2 S can be detected quantitatively in the concentration range 0 to 25 μM and the detection limit was 30 nM. Moreover, probe 1 was successfully used as a sensor to determine H2 S levels in red wine and beer. PRACTICAL APPLICATION Fluorescent probe 1 could be employed as a visible sensor for H2 S. Probe 1 could be used to detect H2 S quantitatively in food simple.

一种基于反应的新型硫化氢荧光探针及其在葡萄酒中的应用

设计并合成了一种基于反应的新型荧光探针 6-cyanonaphthalen-2-yl-2,4- dinitrobenzosulfonate（探针 1），用于检测硫化氢（H2 S）。将 H2S 添加到探针 1 的溶液中导致显着的荧光增加，同时视觉上的颜色从无色变为黄色。重要的是，这种独特的颜色响应表明探针 1 可以用作检测 H2 S 的视觉工具。H2 S 可以在 0 到 25 μM 的浓度范围内定量检测，检测限为 30 nM。此外，探针 1 成功地用作传感器来确定红葡萄酒和啤酒中的 H2 S 水平。实际应用 荧光探针 1 可用作 H2 S 的可见传感器。探针 1 可用于定量检测食品中的 H2 S。
