A novel metal–organic framework {Zn2(tpt)2(tad)2·H2O} (tpt = 2,4,6-tri(pyridin-4-yl)-1,3,5-triazine, H2tda = 2,5-thiophene dicarboxylic acid) with a 3-fold interpenetrating 3D framework was successfully synthesized under hydrothermal conditions. As expected, 1 displays excellent luminescence and can stably exist in different pure organic solvents and acid–base solution. 1 can be considered as an ultrasensitive sensor for detection of Fe3+ ions and PA with high selectivity by fluorescence quenching behaviors. Meanwhile, the fluorescence test plates show the visible color change of Fe3+ ions which can be easily observed by the naked eye in the detection process, which makes Fe3+ ions more easily recognized than various metal ions. In addition, the mechanism of fluorescence quenching is also further discussed.

新型多功能锌金属-有机骨架荧光探针展示了用于检测水溶液中PA和Fe3 +离子的独特灵敏度和选择性
一种新颖的金属有机骨架{Zn 2(tpt)2(tad)2 ·H 2 O}(tpt = 2,4,6-三(吡啶-4-基)-1,3,5-三嗪,H 2在水热条件下成功合成了具有3倍互穿3D骨架的tda = 2,5-噻吩二羧酸)。如预期的那样,1具有出色的发光性能,并且可以稳定地存在于不同的纯有机溶剂和酸碱溶液中。1可被认为是用于通过荧光猝灭行为以高选择性检测Fe 3+离子和PA的超灵敏传感器。同时,荧光测试板显示出Fe 3+的可见颜色变化在检测过程中可以用肉眼轻易观察到的离子,这使得Fe 3+离子比各种金属离子更易于识别。另外,还进一步讨论了荧光猝灭的机理。
