摘要： 合成了两种磺酰胺类化合物, 并研究了其荧光性能. 通过它们对金属阳离子的选择性识别实验, 发现其在乙醇水溶液中均对Fe3+有专一性的识别作用, 并在NH2OH·HCl和H2O2的存在下, 两种化合物对Fe3+都具有氧化-还原荧光“开-关”作用.

关键词: 磺酰胺, 氧化-还原, 荧光“开-关”

Abstract: Two kinds of Tosylamine compounds(I, II) were synthesized and their fluorescence abilities were studied. Through the study of their recognition with Cu2+, Zn2+, Pb2+, Mg2+, Cd2+, Mn2+, Ca2+, Hg2+, Fe2+, Fe3+, Ni2+, Co2+ cations, it was found that both of the two kinds of compounds had recognition to Fe3+ in EtOH/H2O system through a series of iron-reorganization study. The fluorescence was changed by the addition of Fe3+, in which the fluorescence intensity of compounds I, II at 338 nm or 339 nm decreased. Under the co-existence of NH2OH·HCl and H2O2, both of the two compounds showed up that there could be a fluorescence switch by oxidation-reduction of Fe3+.

Key words: Tosylamine, Oxidation-reduction, Fluorescence switch
