摘要

The hard-soft-acid-base (HSAB) and dual-ligand strategies have been used to construct a pillar-layer luminescent metal-organic framework (MOF) {[Zn-2(TRZ)(2)(DBTDC-O-2)]center dot DMAc}(n) (1), in which H2DBTDC-O-2 = S,S-dioxodibenzothiophen-3,7-dicarboxylic acid and HTRZ = 1,2,4-triazole. Thanks to its high stability in water and quadrangle microporous channels, MOF 1 can be served as a platform of recyclable multi-responsive luminescent sensor for Fe3+, Al3+,SiF62-,Cr2O72-, nitrofurantoin (NFT), and nitrofurazone (NFZ) in water. This is the first MOF-based sensor for detecting SiF62- anion via luminescent enhancement effect. Significantly, 1 also represents a unique example to probe NFZ or NFT by using transition metal MOFs in water, which exhibits the most sensitive sensing ability for NFZ (K-sv = 5.2 X 10(4) M-1) and NFT (K-sv = 1.8 x 10(5) M-1) via luminescent quenching.
