摘要/Abstract

一锅法合成了2，2'，2''-（1，3，5-三嗪-2，4，6-三亚胺基）三苯甲酸荧光响应化学传感器（L，H₃TATIB），系统地研究了化合物L对过渡金属离子的识别性能.实验结果显示，在N，N-二甲基甲酰胺（DMF）水溶液中实现了对Fe³⁺和Zr⁴⁺的识别；化合物L在有机溶剂识别中能够有效地识别丙酮.化合物L对Zr⁴⁺和Fe³⁺的检测限分别为3.60×10^-6和1.33×10^-6 mol/L.实验初步探究了化合物L作为荧光探针对人体尿液和水样中Fe³⁺离子的识别.

2,2',2''-(1,3,5-Triazine-2,4,6-triimino)tribenzoic acid (L, H₃TATIB) fluorescence response chemosensor has been synthesized by one pot reaction and its fluorescent behaviors to transition metal ions were systematically investigated. The experimental results show that the recognition of Zr⁴⁺ and Fe³⁺ is realized in N,N-dimethylformamide (DMF) aqueous solution; The compound L can effectively detect acetone in organic solvent. The detection limits of Zr⁴⁺ and Fe³⁺ are 3.60×10^-6 and 1.33×10^-6 mol/L, respectively. It was preliminarily explored that compound L was used as a fluorescent probe to identify Fe³⁺ ion in human urine and water samples.
Key words: fluorescent sensor, Zr⁴⁺ ion, Fe³⁺ ion, acetone, 1,3,5-triazine derivatives
