Synthesis of copper-based metal-organic framework for sensing nitroaromatic compounds

Nitroaromatic compounds in environmental contaminants have threatened human health due to their toxicity and explosivity. MOFs used to environmental contaminants detection has the advantages of highly sensitivity, low cost and rapid response. In this work, the luminescent copper-based metal-organic framework (Cu-MOF) was solvothermally synthesized and further characterized by single-crystal X-ray diffraction, infrared sprectra and powder X-ray diffraction (PXRD). The selectivity and sensitivity of the Cu‐MOF against nitroaromatic compounds were investigated and the limit of detection for 2-nitrophenol sodium salt was 0.0651 μM. In summary, Cu-MOF can be used as a potential highly selective luminescence sensor for 2-nitrophenol sodium salt.
