the fluorescence enhancement. Meanwhile, compound 1 can also serve as a sensor for detecting the trace amounts of Cr (VI) ion and 2,4,6‐trinitrophenol (TNP) with high selectivity and recyclability through the fluorescence quenching effect. Furthermore, the detection mechanisms of compound 1 as a fluorescence sensor for different analytes have been explored in detail.
一种基于4-(2,2'; 6',2''-三吡啶基)-4'-1,1,2-苯基二羧酸(H 2 tbda)的新型配位聚合物[Zn(tbda)] n(1)具有一维双核链结构,在水溶液的pH范围为3-12时具有出色的发光性。特别是,化合物1通过荧光增强作用表现出显着的选择性,抗干扰性和可回收性,可用于感测Cr(III)离子。同时,化合物1还可以用作传感器,通过荧光猝灭效应以高选择性和可回收性检测痕量的Cr(VI)离子和2,4,6-三硝基苯酚(TNP)。此外,化合物1的检测机理 作为用于不同分析物的荧光传感器,已经进行了详细研究。
