硫化氢(H2S)不仅参与人体生理调节, 也对酒的风味和口感有影响. 合成了一种2,4-二硝基苯修饰的苯并吡喃衍生物(DCM-dip), 该化合物在二甲基亚砜(DMSO)/磷酸缓冲溶液(PBS) (V:V=8:2, pH=8)溶液中没有荧光, H2S与其发生硫解反应释放出具有荧光的中间体, 进而实现荧光点亮识别H2S. DCM-dip识别H2S的响应时间为20 min, 检测限为2.82 μmol/L, pH适用范围为8~11, 且具有较大的斯托克斯位移(123 nm), 避免了背景干扰. 应用研究表明, DCM-dip可用于红酒、啤酒样品中检测H2S, 可对活细胞中H2S进行荧光成像.

Hydrogen sulfide (H2S) is not only involved in the physiological regulation of human body, but also has an impact on the flavor and taste of wine. Therefore, a benzopyran derivative modified by 2,4-dinitrobenzene (DCM-dip) was synthesized, which had no fluorescence in dimethyl sulfoxide (DMSO)/phosphate buffered saline (PBS) (V:V=8:2, pH=8) solution. DCM-dip underwent a thiolysis reaction with H2S to release the intermediate with fluorescence, which showed a fluorescence turn-on response for recognition of H2S. DCM-dip recognized H2S with a response time of 20 min, a detection limit of 2.82 μmol/L, pH application range of 8~11 and a large Stokes shift (123 nm), avoiding background interference. The application research indicates that DCM-dip can be used to detect H2S in red wine and beer samples, and image for H2S in living cells.
