One new Zn(II) MOFs based on 3-abit and 2,5-tdc, namely{[Zn(2,5-tdc)(3-abit)]H2O}(n) (1) (2,5-tdc=2,5-thiophenedicarboxylic acid, 3-abit=4-amino-3,5-bis(imidazol-1-ylmethyl)-1,2,4-triazole) has been synthesized and structurally characterized by single crystal and powder X-ray diffractions, elemental analysis, FT-IR spectroscopy and TGA. X-ray structural analysis reveals that 1 displays a two-dimensional (2-D) two-fold interpenetrated framework, constructed by 3-abit and 2,5-tdc single bridges. The strong luminescence and good water-stable nature of this Zn-MOF indicate that it can potentially be used as a luminescent sensor. In this work, 1 can display highly selective and sensitive sensing of Cr(VI) and TNP through luminescence quenching effect. Moreover, the mechanisms of 1 as a multifunctional sensor have been preliminarily studied.
