Abstract

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.
