Iron(III) ions play a vital role in living biological systems, while organic pollutants including pesticides and antibiotics pose a great threat to the ecological environment. Effective detection for these species is crucial for human health and environmental protection. In this work, we designed and synthesized a new amino-decorated bridging ligand H(2)APDA and employed it to react with the environmentally friendly Mg(II) ions to construct a novel magnesium luminescent metal-organic framework (Mg-LMOF), namely [Mg-2(APDA)(2)(H2O)(3)]center dot 5DMA center dot 5H(2)O (Mg-APDA). The as-synthesized Mg-LMOF is a three-dimensional framework with one-dimensional hexagonal channels. These microporous channels are decorated with Lewis-base amino sites and uncoordinated O atoms, which facilitate the Mg-APDA to anchor and recognize various analytes. Mg-APDA can be used as a multiresponsive luminescent sensor to detect Fe(III) ions, pesticides, and antibiotics effectively. To the best of our knowledge, this work represents the first amino-decorated Mg-LMOF as an efficient fluorescent sensor for detecting metal ions, pesticides, and antibiotics simultaneously.
