Luminescent sensing platforms based on lanthanide metal-organic frameworks: Current strategies and perspectives

Zeolite-Like Ln-MOF Luminescent Nanosensor for Highly Efficient Detection of l-Noradrenaline

“…Furthermore, the study unveiled that disruption of the energy transfer processes was responsible for the behavior of the proportional luminescent probe. The dissimilar decline rates in lifetimes when titrating pure Eu-ZMOF, pure Tb-ZMOF (as shown in Figure S8, Table S3 and Table S4), and mixed Eu 0.479 Tb 0.521 -ZMOF suggested interference by l -NE with energy transfers both from the ligand to metal and from Tb 3+ to Eu 3+ . − …”

Solvent-induced luminescence behavior of Ce/Eu@Gd-MOF for ratiometric detection of D2O in H2O

“…Lanthanide metal–organic frameworks (Ln-MOFs) have emerged as a fascinating class of framework materials in recent years, attracting considerable attention. 1–5 The integration of lanthanide ions and organic ligands confers outstanding optical properties to Ln-MOFs, rendering them with extensive applications in biochemical sensing, nonlinear optics, and white light-emitting diodes. 6–8 The solvent environment is one of the most crucial factors affecting the luminescence performance of Ln-MOFs in applications.…”

Construction of a Sensitive Fluorescence Sensor for Convenient 1-HP and UA Detection Relied on a Stable Eu-MOF

“…20−26 Among the MOFs, lanthanide-centered MOFs (Ln-MOFs) feature the attractive superiorities combining the Ln(III) ions with MOFs, such as high specific surface area, adjustable pore volume, characteristic luminescence emission, long lifetimes, and high quantum yields. 27,28 In virtue of these charming properties, fluorescent probes relied on Ln-MOFs have been extensively The sensing mechanisms are further explored:, the synergistic effect of the photoinduced electron-transfer (PET) mechanism and the weak interaction between compound 1 and 1-HP are responsible for 1-HP detection, while for detecting UA, PET mechanism, the weak interaction between compound 1 and UA, and the formation of nonfluorescent substances are the reasonable explanation.…”

“…Compared with the traditional methods for 1-hydroxypyrene and uric acid detection, such as high-performance liquid chromatography, mass spectrometry, electrochemical sensor technologies, and colorimetric method, which are constrained to their insuperable deficiencies including expensive instruments, intricate pretreatment processes, nonreal-time detection, − chemical sensors constructed from metal–organic frameworks (MOFs) have received extensive attention profited from their fascinating advantages: simple synthesis, modifiable structure, high selectivity, and real-time detection. − Among the MOFs, lanthanide-centered MOFs (Ln-MOFs) feature the attractive superiorities combining the Ln­(III) ions with MOFs, such as high specific surface area, adjustable pore volume, characteristic luminescence emission, long lifetimes, and high quantum yields. , In virtue of these charming properties, fluorescent probes relied on Ln-MOFs have been extensively developed and devoted to sensing various substances, including metal ions, − anions, − amino acids, − antibiotics, − biomarkers, − etc.…”
