“…5 Due to the highly toxic and carcinogenic as well as mutagenic nature of Cr 2 O 7 2− , the International Agency for Research on Cancer (IARC) classified Cr 2 O 7 2− as one of the first class of carcinogens. 6 Because of these reasons, the detection of Cr 2 O 7 2− is very important, especially in aqueous medium. 7 In recent years, a rising class of porous solid materials known as metal−organic frameworks (MOFs) have been extensively studied.…”

A new Cd(II)–organic framework with a quinoline-2,6-dicarboxylic acid (H2QDA) ligand having the formula {[Cd(QDA)]·DMF·0.5H2O}n (1) was synthesized by heating a mixture of Cd(ClO4)2·6H2O, H2QDA, concentrated HNO3, and DMF (N,N′-dimethylformamide) at 120 °C for 72 h. A single-crystal X-ray diffraction analysis confirmed that 1 has a rare ptr topology and Cd2+ attains highly distorted trigonal prismatic geometry with a CdO5N configuration. The as-synthesized compound 1 was activated by solvent exchange and drying at 100 °C for 24 h. By using analytical methods such as X-ray powder diffraction (XRPD), Fourier transform infrared (FT-IR), and thermogravimetric analysis (TGA), both 1 and its activated form (1′) were characterized. Compound 1′ exhibits good thermal stability, high water stability, and easy regeneration ability. The compound was used for the selective and sensitive detection of dichromate (Cr2O7 2–) in water via fluorescence quenching. The K SV and detection limit values for Cr2O7 2– in water for 1′ were found to be 9.65 × 104 M–1 and 81.6 nM (linear range: 0–1.2 μM), respectively. The compound also showed good recyclability and structural stability after the sensing experiment. Moreover, the quenching process was fast (30 s) in the presence of 3 mM aqueous Cr2O7 2– solution. The possible mechanism for the quenching effect of 1′ was also investigated. The compound is a promising fluorescent sensor by virtue of its great detection efficiency, reusability, and fast response rate.

“…In our previous research, we have systematically investigated luminescent CP/MOF sensors involving S- and O-donors as basic sites to detect various cations or organic molecules. − The results revealed that the ligands are pivotal to modulate the stability and detection activities of these materials, such as the introduced donors, the flexibility, the conformation, and so on. In order to push the works forward, herein, a novel 3D Cd-CP , namely [Cd(Hcip)(bpea) 0.5 (H 2 O)] n , has been constructed from the reduced Schiff base tricarboxylate ligand H 3 cip.…”

By using the reduced Schiff base tricarboxylate ligand H 3 cip, one novel 3D Cd-based coordination polymer (Cd-CP) with the formula [Cd(Hcip)(bpea) 0.5 (H 2 O)] n (H 3 cip = 5-(3-carboxybenzylamino)isophthalic acid, bpea = 1,2-bis(4-pyridyl)ethane) has been solvothermally synthesized. The prepared Cd-CP possesses a 4-connected CdSO 4 net based on dinuclear {Cd 2 } units. Luminescence measurements revealed that the complex exhibited ratiometric turn-on luminescence responses toward Al 3+ and Cr 3+ with a significant color change, which could be easily distinguished by the naked eye under ultraviolet light. Cd-CP can also respond to Fe 3+ through a turn-off mechanism. Interestingly, the luminescence quenched by Fe 3+ @Cd-CP can be recovered and increased significantly by adding some competitive Al 3+ , while Cr 3+ can only marginally increase the luminescence intensity of Fe 3+ @Cd-CP. Moreover, the detection of the three aforementioned metal ions can be realized by using Cd-CP-coated test papers, extending the potential application regions of the reported material to point-of-care tests and environmental field studies.

Among the recent developments in metal-organic frameworks (MOFs), porous layered coordination polymers (CPs) have garnered attention due to their modular nature and tunable structures. These factors enable a number of properties and applications, including gas and guest sorption, storage and separation of gases and small molecules, catalysis, luminescence, sensing, magnetism, and energy storage and conversion. Among MOFs, two-dimensional (2D) compounds are also known as 2D CPs or 2D MOFs. Since the discovery of graphene in 2004, 2D materials have also been widely studied. Several 2D MOFs are suitable for exfoliation as ultrathin nanosheets similar to graphene and other 2D materials, making these layered structures useful and unique for various technological applications. Furthermore, these layered structures have fascinating topological networks and entanglements. This review provides an overview of different aspects of 2D MOF layered architectures such as topology, interpenetration, structural transformations, properties, and applications.
