摘要：
In recent years, heavy metal ions and nitroaromatic explosives in environmental pollutants have been a serious threat to human health due to their high toxicity, carcinogenicity, and nondegradability. The detection of metal ions and nitroaromatics has become an urgent problem. In this paper, a new water stable luminescent Eu-based metal-organic framework ([Eu(L)(DMF)(2)](n)) was prepared by the reaction of rigid ligand H3L (3,5-bis-(3-carboxyphenoxy)benzoic acid) and Eu (NO3)(3)center dot 6H(2)O under solvothermal conditions. Luminescent detection of the nitroaromatic compounds and metal ions showed that the complex had high sensitivity to Fe3+, o-nitrophenol, p-nitrophenol, and m-nitrophenol.
