摘　　要：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2.82μmol/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 2.82μmol/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.
