Postsynthetic Metalation Metal–Organic Framework as a Fluorescent Probe for the Ultrasensitive and Reversible Detection of PO43– Ions

Abstract: The self-assembly of a zinc salt with the novel ligand 4,4',4″-[(1,3,5-triazine-2,4,6-triyl)tris(sulfanediyl)]tribenzoic acid generated 3D microporous metal-organic frameworks (MOFs), namely, {[Zn(L)(O)(HO)]·4EtOH} . The frameworks with multiple Lewis basic sites exhibit easily sensitized properties. After encapsulation of the Tb cation in this Zn-MOF, the as-obtained fluorescent-functionalized Tb@Zn-MOFs not only maintain distinguished chemical stabilities but also exhibit strong characteristic emissions of t… Show more

“…In addition, the corresponding binding energy data for Tb was displayed in Figure 5b. The peaks at around 1240.9 eV and 1274.7 eV indicate the binding energy of Tb 3d 5/2 and 3d 3/2 [53]. On the basis of above analysis, the peaks corresponding to Tb confirmed the successful incorporation of Tb-(PMDA-Si)-ClO 4 and Tb-(PMDA-Si)-phen-ClO 4 complexes onto the surface of SiO 2 .…”

“…Besides, excessive phosphate and its derivatives can also affect the absorption of calcium ions in the human bodies and cause irreversible harm to people’s life. 2426 As a pollutant anion, PO 4 3– possesses less binding reactive sites and lower reactivity, so detection of PO 4 3– emerges a major challenge in the field of chemosensors. 2729…”

“…19,20,23,24 Recently, lanthanide ions were doped into CPs by post-synthesis method (PSM), and an alternative strategy to construct Ln-CPs and optimize photoluminescence was proposed. 25,26 Any desired uorescent probe can be obtained by changing the molar ratio of reactants. 27,28 Some luminescent CPs have been developed in recent years to effectively simultaneously sense Fe 3+ and Cr 2 O 7…”
