“…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.…”

Herein, a new three-dimensional Eu-MOF, [Me 2 NH 2 ] 2 -[Eu 3 (mtptc) 2 (CH 3 COO) 3 ]•DMA•H 2 O (1), has been elaborately prepared through the reaction of europium nitrate and a symmetric tetra-carboxylate ligand, 5′-methyl-[1,1′:3′,1″-triphenyl]-3,3″,5,5″-tetracarboxylic acid (H 4 mtptc). Noteworthily, compound 1 represents marked stability covering acid−base stability in the pH range of 2−14, thermal stability maintaining skeleton integrity when heated at 350 °C, solvent stability in some common solvents, and air stability in open air more than 4 weeks characterized by powder X-ray diffraction (XRD) and temperature-dependent powder XRD analyses. Remarkably, luminescent sensing measurements manifest that compound 1 is deemed as a hopeful fluorescent probe for rapid recognition of 1-hydroxypyrene (1-HP) and uric acid (UA) equipped with excellent sensitivity with a quenching efficiency of 99.1% for 1-HP and 97.4% for UA. Besides, the luminescent sensing performance of compound 1 toward 1-HP and UA possesses super stability in dimethylformamide/ H 2 O solution, N-(2-hydroxyethyl)piperazine-N′-ethanesulfonic acid buffer solution, and human urine.

“…But lanthanide metal ions can be combined with ligands via coordination interactions to strengthen the fluorescence of the metal ions center. The fluorescence properties of the Ln-MOFs broaden the applications of MOF materials in molecular switching and chemical fluorescence sensors. − For example, luminescent Ln-MOFs have been reported to be applied in the detection of ions, pH, small molecules, biomarkers, , and so forth. However, there are various problems, such as poor stability and low selectivity, in practical applications.…”

Gossypol (Gsp) and antibiotics present in water bodies become organic pollutants that are harmful to human health and the ecological environment. Accurate and effective detection of these pollutants has far-reaching significance in many fields. A new three-dimensional metal–organic framework (MOF), {[Eu3(L)2(HCOO–)(H2O)3]·2H2O·2DMF} n (Eu-MOF), was synthesized from 3,5-bis(2,4-dicarboxylphenyl)nitrobenzene (H4L) ligand and Eu3+ via the solvothermal method in this paper. The Eu-MOF demonstrates strong red fluorescence and can remain stable in different pH solutions. The MOF fluorescence probe could detect organic pollutants through the “shut-off” effect, with a fast response speed and a low detection limit [Gsp, nitrofurantoin (NFT), and nitrofurazone (NFZ) for 0.43, 0.38, and 0.41 μM, respectively]. During the testing process, Eu-MOF exhibited good selectivity and recoverability. Furthermore, the mechanism of fluorescence quenching was investigated, and the recoveries were also good in real samples. This paper introduced a deep learning model to recognize the fluorescence images, a portable intelligent logic detector designed for real-time detection of Gsp by logic gate strategy, and an anticounterfeiting mark prepared based on inkjet printing. Importantly, this work provides a new way of thinking for the detection of organic pollutants in water with high sensitivity and practicality by combining the fluorescence probe with machine learning and logical judgment.
