用于肼检测的新型芘基荧光分子探针的合成与性能OA
Synthesis and Properties of A Novel Pyrenyl Fluorescent Molecular Probe for Hydrazine Detection
利用 1-芘甲醛优良的荧光性质,将其作为母体进行基团修饰,经过 1H-NMR和HRMS对结构进行表征,证实成功构建了肼荧光分子探针PMIDO.在DMSO-H2O体系中,PMIDO只能显示弱的荧光;在加入肼后,在含水量 70%的条件下,显示出强的蓝色荧光,呈现出开灯型的荧光探针特征,检出限可达 1.41×10-7 mol/L.同时,该探针对肼的检测呈现出高选择性和稳定抗干扰性,适用于 5～10 的pH范围,并在 30 s内完成响应.进一步阐述了其荧光检测机制,即与肼反应后生成腙,为反应型肼的荧光检测提供有益参考.
Excessive hydrazine does great harm to the environment and organisms.Hydrazine fluorescent molecular probe PMIDO was successfully constructed by using 1-pyrene formaldehyde as the parent,modified by groups,and characterized by 1H-NMR and HRMS.In the DMSO-H2O system,PMIDO can only show weak fluorescence.However,after the addition of hydrazine,at the water content of 70%,it showed strong blue fluorescence,showing the characteristics of fluorescent probe with light on,and the detection limit reached 1.41×10-7 mol/L.At the same time,the probe show high selectivity and stable anti-interference for the detection of hydrazine,suitable for the pH range of 5～10 systems,complete response within 30s.The fluorescence detection mechanism of probe PMIDO is described,that is,the reaction with hydrazine to from a hydrazone,which provides a useful reference for the fluorescence detection of reactive hydrazine.
