“…As shown in Figure 3c,d, two La1 atoms and two La2 atoms are considered as 8-coordinated nodes, respectively, and the H 6 TDPAT ligands are simplified to 13-connected nodes. The final compound 1 can be simplified to a topology connected by (8,13), and the topology symbol analyzed by TOPOS software is {3 19 •4 45 •5 14 }{3 8 •4 16 • 5 4 }.…”

“…18 In 2022, Chen's group synthesized a Eu-MOF by solvothermal method with 2-amino-4,4′-biphenyl dicarboxylic acid and Eu(NO 3 ) 3 •4H 2 O. 19 Fluorescence sensing experiments showed that it could effectively detect PNP and TNP. To date, the preparation cost and batch production of Ln-MOFs are still extremely limited, and there are few reports on stable visible or near-infrared luminescence in complicated environments.…”

Multiple stimulus responses of the novel triazine frameworks (1− 2) are constructed by the building block Ln x (COO) y with the reaction of a flexible hexacarboxylic acid 2,4,6-tris(3,5-dicarboxyanilino)-1,3,5-triazine (H 6 TDPAT) and corresponding rare earth nitrate under solvothermal conditions. In a similar reaction condition, we successfully introduced 1,1′-[1,4-phenylbis-(methylene)]bis(4,4′-bipyridine) dichloride (pbpyCl 2 ) into the pores of triazine frameworks and obtained compound 3. The effect of the addition amount of pbpyCl 2 on the framework structure is discussed in detail. Compounds 1−3 are characterized by elemental analysis, infrared spectroscopy, ultraviolet spectroscopy, thermogravimetric analysis, and X-ray powder diffraction. Based on the excellent fluorescence sensing properties of compounds 2 and 3, we also explore the fluorescence sensing on nitro compounds and investigate their mechanisms. The results show that 2 has the best fluorescence response on 2,4,6-trinitrophenol (TNP) and 3 has a sensitive detection ability on p-nitrophenol (PNP) and p-nitroaniline (p-NA).

“…Especially, high physiologically toxic nitroaromatics are harmful to (ground)water, soil resources and human health when released into the environment. Therefore, the detection of nitroaromatic compounds is of great significance to environmental monitoring, citizen safety and homeland security [11][12][13][14][15]. At present, the analytical methods for detecting harmful substances in the environment mainly include atomic absorption spectroscopy [16], mass spectrometry [17], optical gas chromatography-mass spectrometry [18], gas chromatography-electron capture detection [19], surface-enhanced Raman spectroscopy [20,21], X-ray imaging [21], thermal neutron analysis [21], electrochemical procedures [20] and ion mobility spectroscopy (IMS) [20,21] and molecularly imprinted polymers (MIPs) [22].…”

Water environment pollution is becoming an increasingly serious issue due to industrial pollutants with the rapid development of modern industry. Among many pollutants, the toxic and explosive nitroaromatics are used extensively in the chemical industry, resulting in environmental pollution of soil and groundwater. Therefore, the detection of nitroaromatics is of great significance to environmental monitoring, citizen life and homeland security. Lanthanide–organic complexes with controllable structural features and excellent optical performance have been rationally designed and successfully prepared and used as lanthanide-based sensors for the detection of nitroaromatics. This review will focus on crystalline luminescent lanthanide–organic sensing materials with different dimensional structures, including the 0D discrete structure, 1D and 2D coordination polymers and the 3D framework. Large numbers of studies have shown that several nitroaromatics could be detected by crystalline lanthanide–organic-complex-based sensors, for instance, nitrobenzene (NB), nitrophenol (4-NP or 2-NP), trinitrophenol (TNP) and so on. The various fluorescence detection mechanisms were summarized and sorted out in the review, which might help researchers or readers to comprehensively understand the mechanism of the fluorescence detection of nitroaromatics and provide a theoretical basis for the rational design of new crystalline lanthanide–organic complex-based sensors.
