Abstract

Based on the mixed carboxylate ligands synthesis strategy, an indium-organic framework, (Me₂NH₂)_1.5[In_1.5(FBDC)(BDC)]·2.5NMF·CH₃CN (1) has been constructed by using the mixed (2,5-di(2',5'-dicarboxylphenyl)-difluorobenzene (H₄FBDC) and terephthalic acid (H₂BDC). Compound 1 contains a 3D intersecting pore system which surface is modified by F atoms, and it has excellent stability in pH = 2-12 aqueous solutions. The activated 1 shows high separation for C₂H₂/CO₂ and C₂H₂/CH₄. Moreover, 1 not only has strong luminescence but also has the high selectivity and sensibility of fluorescence detection to nitrofurazone (NZF) in antibiotic sensing experiments, which can be used as a luminescence sensor for NZF detection.
