Highly sensitive luminescent probe of aniline and trace water in organic solvents based on covalently modified lanthanide metal-organic frameworks

Abstract: A novel europium functionalized metal–organic framework (MOF) named Eu3+@UiO-66-NH2-IM is robustly synthesized via covalent PSM (postsynthetic modification). The ligand of matrix MOF is covalently ...

Luminescent Hybrid Tb3+ Functionalized Metal–Organic Frameworks Act as Food Preservative Sensor and Water Scavenger for NO2–

Abstract: Luminescent Tb3+ functionalized metal–organic frameworks (MOFs) are prepared and act as food preservatives sensor and water scavenger for NO2–. Classical metal–organic frameworks with uncoordinated N atoms in pores are elected as carrier to encapsulate Tb3+ ions. This Tb3+ incorporated material reveals excellent characteristic green luminescence of Tb3+ and good fluorescence stability in water. Subsequently, we choose this probe for sensing NO2– among several food preservative compounds, showing a highly sensitive capability for detection of NO2–; it is then proved that the Dexter energy transfer (DET) causes the luminescent quenching between Tb3+ and NO2–, achieving the detection of NO2–. This probe is also employed to detect the NO2– in real water samples and act as water scavenger to remove the NO2– in drinking water, showing a good removal capacity 3.45 mg (75.0 μmol) of NO2– per gram of particles.
