| 摘 要： | 以2,6-二甲氧基苯甲酸为起始原料得到氨基噻二唑衍生物,通过Gattermann反应合成一种杂环芳族卤化物2-氯-5-(3-氯-2,6-二甲氧基苯基)-1,3,4-噻二唑(L),利用核磁共振波谱仪(NMR)和高分辨率质谱仪(HRMS)等测试手段确定了结构,并将其用作小分子荧光探针检测2,4,6-三硝基苯酚(TNP),系统地研究了其荧光特性,并且结合理论计算,探究了其可能的猝灭机制。 研究结果表明,探针L对TNP具有高选择性、高灵敏度、抗干扰能力强,在较宽的pH值范围内,仍然表现出良好的荧光性能。 具有较低的检测限(4.2×10-7 mol/L),可用于实际水样中TNP的检测。

| Abstract: | The heterocyclic aromatic halide,2-chloro-5-(3-chloro-2,6-dimethoxyphenyl)-1,3,4-thiadiazole(L),was synthesized by Gattermann reaction from the aminothiadiazole derivative.Its structure was characterized by nuclear magnetic resonance spectroscopy(NMR)and high resolution mass spectrometry(HRMS).Probe L was used as a small molecule fluorescent probe to detect 2,4,6-trinitrophenol(TNP),and its fluorescence characteristics were systematically studied.Furthermore,combined with theoretical calculations,the possible quenching mechanism was explored.The results showed that the probe L had high seletivity,high sensitivity and strong anti-interference ability to TNP,and exhibited good fluorescence performance in a wide pH range.It has lower detection limit(4.2×10^-7 mol/L)and can be used for the detection of TNP in actual water samples. |
