A MOF-on-MOF composite encapsulating sensitized Tb(III) as a built-in self-calibrating fluorescent platform for selective sensing of F ions

On–Off Ratiometric Fluorescence Europium(III) Metal–Organic Framework for Quantitative Detection of the Inflammatory Marker Neopterin

“…Recently, a fluorescence sensing method based on lanthanide­(III) metal–organic framework (Ln-MOF) materials has been confirmed to be a promisingly available platform for the detection of hazardous substances due to its superior sensitivity and selectivity, convenient utilization, durable reversibility, and has attracted more and more attention. − Benefiting from the unique photoluminescence behavior of the lanthanide­(III) ions and organic ligands, the effective energy-transfer processes of a fluorescence Ln-MOF material could be adapted to the regulation of the organic ligands for achieving the sensitization process via an “antenna effect”, thus achieving the simultaneous photoluminescence of lanthanide­(III) ions and organic ligands − Moreover, a fluorescence Ln-MOF material can realize the structural modifiable functionality by the encapsulation of some desired fluorescence matrix, thereby providing access to tuning the fluorescence dynamics through the influence of versatile encapsulated fluorescence matrix composites within the Ln-MOF material. − In principle, the regulations of the fluorescence Ln-MOF behaviors could be readily achieved by the optimization of fluorescence centers such as the lanthanide­(III) ions, the organic ligands, and the versatile encapsulated fluorescence matrix composites, − which endow superior applications of a Ln-MOF material for fluorescence sensing behaviors. In general, there have been two fluorescence sensing forms of the Ln-MOF material.…”

A Europium Metal–Organic Framework and Its Polymer Composite Membrane as Switch-Off Fluorescence Sensors for Antibiotic Detection in Lake Water

“…Organic ligands as energy antennas absorb excitation light energy and transfer it to lanthanide centers to obtain high quantum yields and long fluorescence lifetimes (FLTs). Ln-MOFs have been used to detect explosives, − heavy metal cations, − volatile gases, − organic pollutants, − pesticides, − and so forth. Luminescent Ln-MOFs sensing antibiotics become a research hotspot. − …”
