Two series of Ln-MOFs by solvent induced self-assembly demonstrating the rapid selective sensing of Mg²⁺ and Fe³⁺ cations

Abstract

Two series of lanthanide-based metal-organic frameworks, {[Ln(BIPA-TC)0.5(DMA)2(NO3)]·DMA·H2O}n (1-Ln, Ln = Eu, Dy, Sm, Nd) and {[Ln2(BIPA-TC)1.5(DMA)3(H2O)2]·2DMA·2H2O}n (2-Ln, Ln = Eu, Dy, Sm, Nd), were successfully constructed via solvent regulation strategy...

Four Novel Lanthanide(III) Metal–Organic Frameworks: Tunable Light Emission and Multiresponsive Luminescence Sensors for Vitamin B6 and Pesticides

“…For example, multicolored photoluminescence MOFs with dual emission peaks can be synthesized by the incorporation of different Ln 3+ ions into the MOFs, and they present potential applications in display and privacy equipment. , Their luminescence color can be regulated by varying the molar ratio of Ln­(III) ions. In particular, numerous Ln-MOFs have been widely investigated as fluorescent-sensing materials to trace metal cations, anions, small organic molecules, and so on. − …”

Series of TM-OFs as a Platform for Efficient Catalysis and Multifunctional Luminescence Sensing

“…20−26 Transition-metal ions containing d orbitals of d 10 as the valence orbitals, such as Zn(II) and Cd(II), can induce the ligand−metal charge transfer (LMCT) process, making these metals a more common choice for building luminescent MOFs. 27,28 Cadmium salts are relatively inexpensive and abundant on Earth. Cd(II) ions have been shown to form MOFs with diverse structures and topological types, making the Cd(II) ion an excellent metal for building LMOFs.…”

“…The detection of toxic ions and organic pollutants is irreplaceably significant for the protection of the natural environment, plant and animal life, and human health. Luminescent MOFs (LMOFs) have been considered to be superior sensors for sensing applications due to their unique properties. − Transition-metal ions containing d orbitals of d 10 as the valence orbitals, such as Zn­(II) and Cd­(II), can induce the ligand–metal charge transfer (LMCT) process, making these metals a more common choice for building luminescent MOFs. , Cadmium salts are relatively inexpensive and abundant on Earth.

Luminescent MOFs for selective sensing of Ag+ and other ions (Fe(iii) and Cr(vi)) in aqueous solution

“…[15][16][17][18] Metal-organic frameworks (MOFs) are porous crystalline materials formed by self-assembly of organic ligands and metal cations or metal clusters through coordination bonds. [19][20][21][22][23][24] Due to their diverse properties and highly tunable structure, [25][26][27] they have potential applications in the fields of gas storage/ separation, [28][29][30] magnetic applications, 31,32 luminescence, 33,34 catalysis, 35,36 and drug delivery. 37 In our previous work, a series of LMOFs have been reported based on triphenylamine [38][39][40] and tetraphenylethylene.…”
