Abstract
and nitrobenzene with high sensitivity, selectivity, stability and anti-interference ability against the coexistence of other ions or molecules based on high luminescence quenching efficiency. Additionally, Eu-MOF (VI) shows excellent luminescence stability and retains its structural integrity within the pH range of 2-12 in an aqueous solution and its solid sample maintains high thermodynamic stability up to 320 °C. Furthermore, the possible luminescence sensing mechanisms have been discussed in detail, and are supported by PXRD analysis, UV-vis spectroscopy, X-ray photoelectron spectroscopy (XPS) or density functional theory (DFT).
