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 Co2+,Ni2+,Cu2+,Zn2+,Cd2+,Hg2+,Fe3+and Mg2+metal ions were investi-gated.Preliminary results indicate the better selectivity of L1 toward Cu2+compared with Co2+,Ni2+,Zn2+, Cd2+,Hg2+,Fe3+ and Mg2+ ions.
