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.

“…Further, we have reported the crystal structure, supramolecular structure, and physical properties of chiral 3D [{Co(2,5-pdc)(H 2 O) 2 }H 2 O] n (2,5-pdc = 2,5-pyridine dicarboxylate) framework . It may be noted that non-centrosymmetric 2,5-pdc is a fairly rigid ligand, and it exhibits 23 coordination modes. , On the other hand, flexible aldrithiol (ald-4) can be used as a very efficient linker for synthesizing organometallic complexes together with carboxylate ligands. , Thus, from the standpoint of rational design of a new solid state structure, synthesizing a Cu containing 3D MOF built up with 1D helical SBUs having both 2,5-pdc and ald-4 linkers appears to be very promising. Further, if this attempt becomes successful, then it will be interesting to explore the possibility of synthesizing CuO nanoparticles through thermal decomposition of the obtained framework.…”

Herein, we have reported the synthesis, crystal structure, thermogravimetric property, and photoluminescence activity of a new Cu-based metal organic framework (MOF): {[Cu2(2,5-pdc)2(ald-4)(H2O)2]·3H2O,MeOH} n (where 2,5-pdc = 2,5-pyridine-dicarboxylate, ald-4 = aldrithiol-4) along with catalytic activity of CuO nanoparticles (Cu-NPs) derived from the MOF for green synthesis of organic molecules having biological relevance. The regular arrangement of metal centers and the presence of oxygen and carbon in metal–organic frameworks (MOFs) enable us to utilize them as template/precursor for the synthesis of monodispersed metal-oxide and metal-carbide nanoparticles having a high surface area with well-defined and uniform morphology. The MOF derived oxide nanoparticles generally exhibit improved catalytic activities and product selectivity and significantly reduce the chemical waste production. The structural analysis has revealed that in the complex under investigation the 2,5-pdc bridges the Cu(II) centers to form both left-handed and right-handed infinite one-dimensional helical chains, and the complex is a three-dimensional achiral framework composed of neighboring two-dimensional sheets of opposite chirality. The thermogravimetric study suggests that the framework is stable up to 500 °C. Single phase, highly crystalline, nearly monodispersed, and spherical CuO-NPs having an average particle size of ∼27.9 nm has been synthesized by heating the framework at 650 °C for 4 h. The CuO-NPs are characterized by using powder X-ray diffraction, high resolution transmission electron microscopy, selected area electron diffraction, energy dispersive X-ray spectroscopy, and dynamic light scattering technique. Further, the crystal structure of the CuO-NPs has also been illustrated by Rietveld refinement of powder pattern. Finally, the as-synthesized CuO-NPs were employed in the one-pot three component Strecker synthesis of α-aminonitriles via the condensation of benzaldehyde, aniline, and trimethylsilyl cyanide under solvent-free condition. This work will be helpful in utilizing the MOF derived oxide nanoparticles for development of sustainable chemical processes.

Metal organic frameworks (MOFs) are crystalline materials based on connections between metal ions through organic ligands. The combination of polycarboxylate anions and dipyridyl ligands is an effective strategy for producing extended structures. In this sense, the combination of bpa with m‐bdc [bpa = 1,2‐bis(4‐pyridyl)ethane, m‐bdc = 1,3‐benzenedicarboxylate] has produced three new CuII‐based networks with different dimensionalities, namely the 1D [Cu(m‐bdc)(bpa)0.5(H2O)dmf]·0.5H2O (1, synthesis based on sonication and slow evaporation), the 2D [Cu6(m‐bdc)6(bpa)6(dmf)3]·8dmf (2, microwave synthesis) and the 3D [Cu4(m‐bdc)4(bpa)2dmf]·dmf (3, microwave synthesis). The three compounds have been structurally characterized by means of single‐crystal X‐ray diffraction, IR and UV/Vis spectroscopy and elemental analysis. An unprecedented CuII dimer has been observed for compound 3. The thermal behaviour of the compounds was analysed by thermogravimetry (TG/DSC) and X‐ray thermodifractometry (TDX), and it was concluded that the dimensionality plays an important role in their thermal properties. Electronic paramagnetic resonance and magnetic susceptibility measurements for compounds 1 and 3 showed that antiferromagnetic interactions exist between the metal ions.
