| 摘 要： | 文中设计合成了新的含硫原子的席夫碱（Schiff base）衍生物CzSB,该化合物可以作为荧光增强型Hg2＋探针.通过紫外-可见光吸收光谱和荧光发射光谱研究了探针CzSB对Hg2的响应过程,Hg2＋的加入显著增强探针的荧光发射.探针CzSB对金属离子的识别作用和竞争选择能力也经由荧光光谱进行了研究,结果表明该探针对Hg2＋具有较高的选择响应性并且不受其他常见金属离子的干扰.初步探讨了该探针分子与Hg2的结合模式和荧光增强机理,Job曲线表明探针CzSB与Hg2以1∶2计量比配位.

| Abstract: | A novel fluorescence turn-on probe based on a new schiff base derivative CzSB containing sul- fur atoms is designed and prepared for detection of Hg2＋ in the presence of other competing metal ions in acetonitrile. The addition of Hg2＋ significantly enhances the fluorescence emission intensity of CzSB. The turn-on behavior of the probe is ascribed to the metal ion- induced conformational changes from the weak N-phenyl carbazole monomer emission to intensive excimer emission. The photophysical properties and Job plot of CzSB toward Hg2. continue a 1 ： 2 （ CzSB-Hg2＋ ） binding mode and a possible binding mech- anism. |
