| 摘 要： | 设计合成了荧光传感分子水杨醛-4-甲氧基苯甲酰腙(SAMB),通过IR、1HNMR和元素分析确证了其结构,利用紫外-可见吸收光谱和荧光光谱考察了其对不同阳离子的识别作用。结果表明,SAMB的荧光发射对锌离子表现出高选择性响应,且形成1∶1型配合物。乙醇中锌离子的加入导致SAMB的荧光增强328倍,而其他过渡金属离子只引起SAMB的荧光的略微增强。初步探讨了受体分子与锌离子的结合模式与荧光增强机理。

| Abstract: | A fluorescent chemosensor,namely salicylaldehyde-4-methoxybenzoylhydrazone(SAMB),was synthesized and characterized by IR,1HNMR and elemental analysis.SAMB was found to recognize transition metal ions such as Zn2+,Co2+,Ni2+,Cu2+,Cd2+,Hg2+,Ag+,Fe2+,Fe3+ and Pb2+ via its UV-vis spectra and fluorescence spectra.Its florescence showed a highly selective response to Zn2+ and a 1:1 stoiehiometric complex was formed between SAMB and Zn2+.In ethanol,Zn2+ induced a dramatic enhancement in the fluorescence of SAMB by 328 folds,whereas the other transition metal ions had little influence.Mechanism of enhancement of SAMB’s fluorescence by Zn2+ was briefly discussed. |
