摘要
通过Reimer-Tieman反应将荧光素甲酰化得到中间体醛基荧光素(L2),再与邻氨基苯酚缩合,得到荧光素醛缩邻氨基苯酚(L1).研究了L1、L2及L1与金属离子Co2+,Ni2+,Cu2+,Zn2+,Cd2+,Hg2+,Fe3+和Mg2+形成的络合物的荧光性质.实验结果表明:相对于Co2+,Ni2+,Zn2+,Cd2+,Hg2+,Fe3+和Mg2+,L1对Cu2+具有更好的选择性.
A novel fluorescent compound （L1） was synthesized by Reimer-Tieman reaction of fluorescein and further coupling reaction with o-hydroxyaniline.The fluorescence properties of compounds L1, L2 and the complexes from L1 with Co22＋ , Ni22＋ , Cu22＋ , Zn22＋ , Cd22＋, Hg2＋, Fe32＋ and Mg22＋ metal ions were investi- gated.Preliminary results indicate the better selectivity of L1 toward Cu22＋ compared with Co22＋, Ni22＋, Zn22＋, Cd22＋, Hg2＋, Fe32＋ and Mg22＋ ions.
