以3-羟基-2-萘甲酰肼和4-二苯氨基苯甲醛为原料,设计合成了一种新型萘甲酰腙铜离子荧光探针L(N'-(4-(二苯胺基)亚苄基)-3-羟基-2-萘酰肼),并通过,1,H NMR、,13,C NMR、HR-MS、IR和X射线单晶衍射法对L的结构进行了表征。在H,2,O/DMSO(,V∶V,=3∶7,pH=7)溶液体系中,可以高选择性和高灵敏性识别Cu,2+,。通过质谱法、核磁滴定和DFT计算对L与Cu,2+,可能的作用机理进行了研究。通过将L掺杂到聚丙烯酰胺(PAM)中,制备了凝胶(PAML)。研究表明,PAML对Cu,2+,有很好的吸附性能,且不受其他离子的干扰,对水中Cu,2+,去除率可以达到96.99%,并且在紫外灯下通过肉眼很容易进行区分。之后通过SEM-EDS对PAML吸附前后的微观形貌和成分进行了分析。
A novel Schiff base fluorescent probe (N'-(4-(diphenylamino)benzylidene)-3-hydroxy-2-Naphtho-hydrazide)(L) was designed and synthesized using 3-hydroxy-2-naphthoic acid hydrazide and 4-diphenylaminobenzaldehyde as raw materials. The structure of L was characterized through,1,H NMR,13,C NMR, HR-MS, IR and X-ray. The study found that probe L showed high sensitivity and selectivity response to copper ions(Cu,2+,) in H,2,O/DMSO(,V,∶,V,=3∶7, pH=7) solution. The possible mechanism of coordination between L and Cu,2+, was studied by HR-MS,1,H NMR and DFT calculation. PAML was prepared by the method of doping L into polyacrylamide(PAM). PAML had high adsorption of Cu,2+, and the removal rate of Cu,2+, by PAML in water reached 96.99%, in addition, the color change could be distinguished by naked eyes under UV lamp. The microscopic morphology of PAML before and after adsorption of Cu,2+, was observed by SEM-EDS.
