| 摘 要： | A hydroxyl substituted phenolic Schiff base 1, used as sensor for detection of Zn^2＋, was synthesized and investigated. It was found that a strong fluorescence emission was observed when 1 bound to Zn^2＋ in acetonitrile, whereas no fluorescence emission was detected when 1 bound to other metal ions （Fe^2＋, Co^2＋, Ni^2＋, Cu^2＋, Cd^2＋, Hg^2＋, Mg^2＋, Pb^2＋, Ca^2＋, Ba^2＋, Sr^2＋） except for Mg^2＋, for which a weak fluorescence emission was detected in the same condition. Competition experiment showed that no obvious interference was observed in its fluorescence while 1 performed the titration with Zn^2＋ in the different mixtures of metal ions. To understand the site where Zn^2＋ coordinated to the ligand and the mechanism of binding, three other hydroxyl substituted phenolic Schiff bases 2-4 were synthesized and their binding reactions with Zn^2＋were also investigated.

| Abstract: | A hydroxyl substituted phenolic Schiff base 1,used as sensor for detection of Zn~(2+),was synthesized and inves- tigated.It was found that a strong fluorescence emission was observed when 1 bound to Zn~(2+) in acetonitrile, whereas no fluorescence emission was detected when 1 bound to other metal ions (Fe~(2+),Co~(2+),Ni~(2+),Cu~(2+),Cd~(2+), Hg~(2+),Mg~(2+),Pb~(2+),Ca~(2+),Ba~(2+),Sr~(2+) except for Mg~(2+),for which a weak fluorescence emission was detected in the same condition.Competition experiment showed that no obvious interference was observed in its fluorescence while 1 performed the titration with Zn~(2+) in the different mixtures of metal ions.To understand the site where Zn~(2+) coordinated to the ligand and the mechanism of binding,three other hydroxyl substituted phenolic Schiff bases 2--4 were synthesized and their binding reactions with Zn~(2+) were also investigated. |
