A novel dicoumarin-derived hydrogen sulfide (H2S) selective fluorescent “turn-on” probe 3-(2,4-dinitrobenzenesulfonate)-dicoumarin (DC-HS) created by covalent bonding between the 2,4-dinitrobenzenesulfonyl (DNBS) and the 3-hydroxy-dicoumarin (DC-OH) units. Upon the addition of H2S, the probe DC-HS solution's fluorescence significantly increased, and its appearance is changed from practically colorless
一种新型双香豆素衍生硫化氢 (H 2 S) 选择性荧光“开启”探针 3-(2,4-二硝基苯磺酸盐)-双香豆素 (DC-HS) 由 2,4-二硝基苯磺酰基 (DNBS) 之间的共价键合产生和 3-羟基双香豆素 (DC-OH) 单元。加入H 2 S后,探针DC-HS溶液的荧光显着增强,外观由几乎无色变为亮黄色。探针 DC-HS 还显示出显着的荧光放大,可在 0–1.5 μM 的浓度范围内定量检测,并且具有低检测限或 0.2 nM 的检测限。此外,所开发的荧光分子回收率高、准确度高,成功用于H 2的分析。红酒样品中的 S。
