A water-stable europium-MOF as a multifunctional luminescent sensor for some inorganic ions and dichloromethane molecule

A highly stable Eu-MOF multifunctional luminescent sensor for the effective detection of Fe3+, Cr2O72−/CrO42− and aspartic acid in aqueous systems

“…17 Now, MOFs have been widely used in production and life, and have broad application prospects in catalysis, medicine, gas adsorption and separation, fluorescence, chemical sensing and other fields. 18 Luminescent metal organic frameworks have shown great potential sensing properties in various fields, such as explosives, metal ions, anions, amino acids, solvent molecules, temperature and so on. 19 It is very important to select suitable organic ligands and metal salts to construct stable light-emitting metal organic frameworks for chemical sensing.…”

Multifunctional fluorescent Eu-MOF probe for tetracycline antibiotics and dihydrogen phosphate sensing and visualizing latent fingerprints

“…The lost electron density at the europium core, caused by the more electronegative P–O bonds, leads to an increase in 3d binding energy. 51 These experimental studies (FT-IR and XPS) demonstrated that the Eu–P–O bonds influence the coordination environment of the ligand with Eu 3+ , resulting in a partial interruption of energy transfer between the organic ligand and metal center, leading to the decrease in fluorescence intensity. In addition to the more negative P–O bond, the hydrogen-bonding characteristics between H 2 PO 4 − and Eu-MOF may be the basis of the remarkable fluorescence quenching of Eu-MOF by H 2 PO 4 − over other anions.…”

A multifunctional fluorescent Cd-MOF probe: its synthesis, structure, and sensing properties

“…1–11 To date, investigations on topological structures and various functionalizations of MOFs have greatly broadened the elaboration of coordination compounds, among which luminescent MOFs have proved to be promising probe materials due to their fluorescent sensing properties toward common inorganic ions, organic molecules, explosives, biomarkers, etc. 12–15…”
