用于肼检测的新型芘基荧光分子探针的合成与性能
Synthesis and Properties of A Novel Pyrenyl Fluorescent Molecular Probe for Hydrazine Detection
摘要
Abstract
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.关键词
