| 摘 要： | 以苯并咪唑胺为原料,通过与2,4-二羟基苯甲醛反应合成了标题化合物,并利用IR和NMR对其结构进行表征。通过紫外吸收光谱和荧光光谱研究其对不同金属离子的识别作用。结果表明,金属离子的加入,使目标化合物的紫外吸收光谱和荧光光谱发生了不同程度的变化,尤其是对Zn2+的识别能力最佳,具有较强的专一识别能力和抗干扰性,其荧光检出限为3.5×10-7 mol/L。同时,通过核磁滴定法对目标化合物和Zn2+的配位方式进行了探讨。

| Abstract: | 4-(1 H-Benzimidazol-2-imino)methyl]-1,3-benzenediolwas synthesized from benzimidazole amine and 2,4-dihydroxybenzaldehyde,and its structure was characterized by IR and NMR.The recognition of different metal ions was studied by UV absorption spectrum and fluorescence spectrum.The results showed that the addition of metal ions changed the absorption spectrum and fluorescence spectrum of the target compound in different degrees,especially the best recognition of Zn2+,with strong specific recognition ability and anti-interference,and the fluorescence detection limit was 3.5×10-7 mol/L.At the same time,the coordination mode between the target compound and Zn2+ was discussed by NMR titration. |
