“…It will not be an exaggeration to state that carboxylate complexes constitute one of the most studied classes of coordination compounds. [1][2][3][4][5] Currently, the number of corresponding structures deposited to the Cambridge Structural Database (CSD) exceeds 14 000, and these are extremely diverse, representing dozens of different structural motifs. [6][7][8][9][10][11][12] Within our recent research, we focused on halogensubstituted arenecarboxylates as ligands.…”

“…The rational design of MOFs is very challenging and relies on the rational selection of linkers and metal ions. , Carboxylate donor ligands are very important because they have strong coordination abilities in different ways that allow them to meet the geometric needs of metal centers, which leads to higher dimensions and interesting topologies. − Pb(II), as a heavy metal ion in the p-block, has the characteristics of a large radius and multiple coordination numbers, which provides a unique opportunity for constructing a new type of MOF with variable topology and interesting properties. − However, to date, most of the studies on MOFs have mainly focused on lanthanide elements and d-block transition metals, while less attention has been given to MOFs based on p-block main group metals. , Therefore, the development of innovative Pb-based MOFs and their potential applications is very important.…”

The misuse of organic pollutants such as nitrofuran antibiotics (NFAs) and 2,6-dichloro-4-nitroaniline (DCN) has become a hot topic of global concern, and developing rapid, efficient, and accurate techniques for detecting NFAs and pesticides in water is a major challenge. Here, we designed a novel leadbased anion 2D metal−organic framework (MOF){[(CH 3 ) 2 NH 2 ] 2 [Pb(TCBPE)-(H 2 O) 2 ]} n (F3) with interlocking structures, in which TCBPE stands for 1,1,2,2tetra(4-carboxylbiphenyl)ethylene. Powder X-ray diffraction and thermogravimetric analysis revealed that F3 has excellent chemical and solvent stability. It is worth noting that F3 has a grinding discoloration effect. The solvent-protected grinding approach achieved F3B with a high quantum yield (QY = 73.77%) and blue fluorescence, while the direct grinding method produced F3Y with a high quantum yield (QY = 37.27%) and yellow−green fluorescence. Importantly, F3B can detect NFAs in water rapidly and sensitively while remaining unaffected by other antibiotics. F3Y can identify DCN in water quickly and selectively while remaining unchanged by other pesticides. F3B demonstrated high selectivity and rapid response to NFAs at a limit of detection (LOD) as low as 0.26 μM, while F3Y indicated high selectivity and responded quickly to DCN in water at an LOD as low as 0.14 μM. The method was successfully applied to detect NFAs in actual water samples of the fish tanks and ponds as well as the pesticide DCN in soil samples. The recovery rates were 97.0−105.15% and 102.2− 106.48%, and the relative standard deviations were 0.63−1.45% and 0.29−1.69%, respectively. In addition, F3B and F3Y can be made into fluorescent test papers for the visual detection of NFAs and DCN, respectively. Combined with experiments and density functional theory calculations, the mechanism of fluorescence quenching of MOFs by target analytes was also revealed.

“…The porosity of MOFs could be systematically tuned in a wide range by variation of the topology and the length of the organic linker [1][2][3][4][5][6][7][8], while some of the physical properties of the framework mainly depend on the nature of metal centers [9][10][11][12][13]. Particularly, lanthanide coordination compounds are widely studied in magnetic and luminescent applications due to the unique electron configuration of the corresponding Ln(III) cations [14][15][16][17][18]. Luminescent porous MOFs containing lanthanide ions attract special interest as sensors for various ions or small molecules by tailoring both framework affinity towards certain substrates and analytical signal output.…”

Cinnamal Sensing and Luminescence Color Tuning in a Series of Rare-Earth Metal−Organic Frameworks with Trans-1,4-cyclohexanedicarboxylate

Three isostructural metal–organic frameworks ([Ln2(phen)2(NO3)2(chdc)2]·2DMF (Ln3+ = Y3+ for 1, Eu3+ for 2 or Tb3+ for 3; phen = 1,10-phenanthroline; H2chdc = trans-1,4-cyclohexanedicarboxylic acid) were synthesized and characterized. The compounds are based on a binuclear block {M2(phen)2(NO3)2(OOCR)4} assembled into a two-dime nsional square-grid network containing tetragonal channels with 26% total solvent-accessible volume. Yttrium (1)-, europium (2)- and terbium (3)-based structures emit in the blue, red and green regions, respectively, representing the basic colors of the standard RGB matrix. A doping of Eu3+ and/or Tb3+ centers into the Y3+-based phase led to mixed-metal compositions with tunable emission color and high quantum yields (QY) up to 84%. The bright luminescence of a suspension of microcrystalline 3 in DMF (QY = 78%) is effectively quenched by diluted cinnamaldehyde (cinnamal) solutions at millimolar concentrations, suggesting a convenient and analytically viable sensing method for this important chemical.
