Abstract:
As an emerging type of porous material, metal- organic frameworks (MOFs) have been developed as sensors for monitoring environmental pollutants in water. It is of high significance to develop fluorescent MOFs with simple precursors for selective detection of toxic Fe3+ ions. In this work, we present a water-stable two-fold interpene-trated indium- based metal- organic framework (NH2 Me2) [In(fdc)2] ·2H2 O named BUT- 205 (BUT stands for Beijing University of Technology, H2 fdc=furan-2,5-dicarboxylic acid) constructed from a biomass-derived ligand. BUT-205 has been structurally characterized by single-crystal X-ray diffraction. BUT-205 was an efficient sensor for Fe3+ ions in water with high sensitivity and selectivity. The limit of detection (LOD) was calculated to be 1.3 μmol·L-1 being lower than the US- EPA (U. S. Environmental Protection Agency) standard (15.7 μmol·L-1) in drinking water. Furthermore, BUT-205 could be recycled and used for at least four cycles. CCDC: 2033659. © 2022, Chinese Chemical Society. All rights reserved.
