摘要:
合成了一种1,2,3-中氮茚三甲酸三乙酯3(化合物3),并用红外、核磁表征了其结构.紫外光谱研究表明其最大吸收峰在325 nm;荧光光谱分析结果显示在不同pH值溶液中,随着碱性增强化合物3的最大荧光发射波长发生蓝移且强度逐渐增大至最大值;金属离子识别研究发现化合物3对Cu2+有着较好的选择性识别能力,并且灵敏度较高,可作为Cu2+荧光识别探针.
Abstract:
Triethyl indolizine-1,2 ,3 -tricarboxylate 3( compound 3) was prepared and characterized by IR,1H NMR. Ultraviolet spectroscopy studies showed the maximum absorption peak at 325 nm. The fluorescence spectra of the compound in different pH buffer solutions were studied. The results indicated that the fluorescence properties were affected apparently by the pH value. With the increasing of the pH, the fluorescent intensity of compound 3 could be increased, and the emission wavelength was blue shifted. The influence of different metal ions was measured, so as to find compound 3’s recognizing properties on some metal ions. We find fluorescence can be decreased evidently by the copper ions, so compound 3 is promising to be the fluorescent probes for copper ions.
