“…7 Metal−organic frameworks (MOFs) are porous solid-state materials composed of organic ligands (polytopic ligands) bridging single metal ions or clusters. 8,9 Their modular porous system, in addition to their facile functionalization via their organic and/or inorganic backbone, offers their potential deployment in various applications, such as gas storage, separation, catalysis, 10,11 lighting purposes, 12 photocatalysis, 13 and chemical sensing. The desirability of MOFs for sensing applications stems from their structural tunability and chemical diversity, enabling the tuning of both the chemical reactivity and their pore size by isoreticulation and decoration with various functional groups, respectively.…”

The ongoing global industrialization along with the notable world population growth is projected to challenge the global environment as well as pose greater pressure on water and food needs. Foreseeably, an improved irrigation management system is essential and the quest for refined chemical sensors for soil-moisture monitoring is of tremendous importance. Nevertheless, the persisting challenge is to design and construct stable materials with the requisite sensitivity, selectivity, and high performance. Here, we report the introduction of porous metal–organic frameworks (MOFs), as the receptor layer, in capacitive sensors to efficiently sense moisture in two types of soil. Namely, our study unveiled that Cr-soc-MOF-1 offers the best sensitivity (≈24,000 pF) among the other tested MOFs for any given range of soil-moisture content, outperforming several well-known oxide materials. The corresponding increase in the sensitivities for tested MOFs at 500 Hz are ≈450, ≈200, and ≈30% for Cr-soc-MOF-1, Al-ABTC-soc-MOF, and Zr-fum-fcu-MOF, respectively. Markedly, Cr-soc-MOF-1, with its well-known water capacity, manifests an excellent sensitivity of ≈450% in clayey soil, and the analogous response time was 500 s. The noted unique sensing properties of Cr-soc-MOF-1 unveils the great potential of MOFs for soil-moisture sensing application.

“…Thus far, thousands of MOFs have been reported, including Materials of Institutes Lavoisier (MIL), Universiteit I Oslo (UIO), Zeolitic imidazolate framework (ZIFs), and Hong Kong University of Science and Technology (HKUST). Although these catalysts exhibit remarkable electrochemical performance, mostly pristine MOFs have associated with drawbacks such as inadequate stability, low conductivity, and poor activity [3,4,[7][8][9][10][11][12]. Therefore, developing a MOF catalyst with excellent conductivity and cycling stability is still a challenging task.…”

Metal–organic frameworks (MOFs), as a new generation of intrinsically porous extended crystalline materials formed by coordination bonding between the organic ligands and metal ions or clusters, have attracted considerable interest in many applications owing to their high porosity, diverse structures, and controllable chemical structure. Recently, 2D transition-metal- (TM-) based MOFs have become a hot topic in this field because of their high aspect ratio derived from their large lateral size and small thickness, as well as the advantages of MOFs. Moreover, 2D TM-based MOFs can act as good precursors to construct heterostructures with high electrical conductivity and abundant active sites for a range of applications. This review comprehensively introduces the widely adopted synthesis strategies of 2D TM-based MOFs and their composites/derivatives. In addition, this paper summarizes and highlights the recent advances in energy conversion and storage, including the hydrogen evolution reaction, oxygen evolution reaction, oxygen reduction reaction, CO2 reduction reaction, urea oxidation reaction, batteries, and supercapacitors. Finally, the challenges in developing these intriguing 2D layered materials and their composites/derivatives are examined, and the possible proposals for future directions to enhance the energy conversion and storage performance are reviewed.

“…The design and the synthesis of macropore open metal-organic frameworks (MOFs) or coordination polymers (CPs) based on metal centres or clusters are of great interest for their promising potential applications in several different fields as for example in gas storage and separation, host–guest chemistry, catalysis, and fluorescence sensing [ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 ]. Current interest is mainly devoted to the construction of metal–organic frameworks (MOFs) or coordination polymers (CPs) through coordination of metal ions with multifunctional organic ligands as connectors [ 9 , 10 , 11 , 12 , 13 , 14 , 15 ].…”

Fluoride ion (F−) is one of the most hazardous elements in potable water. Over intake of F− can give rise to dental fluorosis, kidney failure, or DNA damage. As a result, developing affordable, equipment-free and credible approaches for F− detection is an important task. In this work, a new three dimensional rare earth cluster-based metal-organic framework assembled from lanthanide Y(III) ion, and a linear multifunctional ligand 3-nitro-4,4′-biphenyldicarboxylic acid, formulated as {[Y(μ3-OH)]4[Y(μ3-OH)(μ2-H2O)0.25(H2O)0.5]4[μ4-nba]8}n (1), where H2nba = 3-nitro-4,4′-biphenyldicarboxylic acid, has been hydrothermally synthesized and characterized through infrared spectroscopy (IR), elemental and thermal analysis (EA), power X-ray diffraction (PXRD), and single-crystal X-ray diffraction (SCXRD) analyses. X-ray diffraction structural analysis revealed that 1 crystallizes in tetragonal system with P4¯21m space group, and features a 3D framework with 1D square 18.07(3)2 Å2 channels running along the [0,0,1] or c-axis direction. The structure of 1 is built up of unusual eight-membered rings formed by two types of {Y4O4} clusters connected to each other via 12 μ4-nba2− and 4 μ3-OH− ligands. Three crystallographic independent Y3+ ions display two coordinated configurations with a seven-coordinated distorted monocapped trigonal-prism (YO7) and an eight-coordinated approximately bicapped trigonal-prism (YO8). 1 is further stabilized through O-H⋯O, O-H⋯N, C-H⋯O, and π⋯π interactions. Topologically, MOF 1 can be simplified as a 12-connected 2-nodal Au4Ho topology with a Schläfli symbol {420·628·818}{43}4 or a 6-connected uninodal pcu topology with a Schläfli symbol {412·63}. The fluorescent sensing application of 1 was investigated to cations and anions in H2O. 1 exhibits good luminescence probing turn-on recognition ability toward F− and with a limit detection concentration of F− down to 14.2 μM in aqueous solution (Kec = 11403 M−1, R2 = 0.99289, σ = 0.0539). The findings here provide a feasible detection platform of LnMOFs for highly sensitive discrimination of F− in aqueous media.
