| 摘 要： | 设计并合成了一种新型长链烷氧基酰腙衍生物1-(2,4-二硝基苯基)-2-(4-(十四烷氧基)亚苄基)肼R,系统研究了受体R对9种阴离子(F-、Cl-、Br-、I-、HSO-4、NO-3、ClO-4、H2PO-4、Ac-)的紫外-可见吸收光谱(UV-Vis)及裸眼识别性能。 结果表明,该受体在二甲基亚砜(DMSO)体系中对F-、Ac-和H2PO-4表现出良好的UV-Vis及裸眼识别能力。 此外,在H2O/DMSO(体积比1∶9)体系中可对F-实现单一UV-Vis及裸眼识别,且检出限可达7.02×10-7 mol/L,同时制备了受体R对阴离子的检测试纸,Job曲线表明受体与阴离子形成1∶1型配合物。 F-离子的识别机理为“氢键型”响应识别现象。

| Abstract: | A new long-chain alkoxyphenylhydrozone derivative, 1-(2,4-dinitrophenyl)-2-(4-(tetradecyloxy) benzylidene) hydrazine, was designed and synthesized. The ultraviolet-visible (UV-Vis) spectra and naked-eye recognition property of the receptor R for nine kinds of anions (F-, Cl-, Br-, I-, HSO-4, NO-3, ClO-4, H2PO-4, Ac-) were studied. The results indicate that the receptor R shows high UV-Vis and naked-eye recognition property towards F-, Ac- and H2PO-4 in dimethylsulfoxide (DMSO) solution. Single colorimetric recognition of F- is found by UV-Vis analysis and naked-eye recognition in H2O/DMSO (1/9) solution, and the LOD (limit of detection) of receptor R for F- is 7.02×10-7 mol/L. The naked recognition paper of receptor R is prepared, and the Job's plot indicates the formation of complex between receptor R and F- is in 1∶1 stoichiometric ratios. The recognition mechanism of receptor R is the “hydrogen-bond” recognition. |
