“…Gas separation is of particular interest when exploring the functionalities of MOFs as they are very useful for obtaining highly pure gases in industry. We have therefore also been very interested in the use of porous MOF materials for gas separation . Currently, it is very popular to deduce the selectivity of MOFs towards binary gas mixtures by utilizing the well‐known ideal adsorbed solution theory (IAST) calculation with the help of the dual‐site Langmuir–Freundlich (DSLF) model .…”

“…Coordination polymers (CPs) continue to be a subject of considerable current interest, as they provide new chemistry in addition to their versatile applications in several contemporary areas of materials research. − In constructing a CP, both the metal ions as well as the linkers play vital roles in terms of directing the overall structure besides the nature and sizes of the voids. Particularly, in a two-dimensional (2D) coordination network the guest molecules can converge due to favorable host–guest interactions leading to catalysis, sensory applications, and so on. − The linker H 2 L has been designed keeping the aforesaid aspects in mind. It forms a 2D framework, {[Zn 3 ( L ) 3 (urotropine) 2 ]·2DMF·3H 2 O} n ( 1 ) (DMF = dimethylformamide) in the presence of urotropine (Scheme ).…”

The solvothermal reaction of Zn(NO)·6HO and a linear dicarboxylate ligand HL, in the presence of urotropine in N,N'-dimethylformamide (DMF), gives rise to a new porous two-dimensional (2D) coordination network, {[Zn(L)(urotropine)]·2DMF·3HO} (1), with hxl topology. Interestingly, framework 1 exhibits excellent emission properties owing to the presence of naphthalene moiety in the linker HL, that can be efficiently suppressed by subtle quantity of nitro explosives in aqueous medium. Furthermore, presence of urotropine molecules bound to the metal centers, 1 is found to be an excellent heterogeneous catalyst meant for atom-economical C-C bond-forming Baylis-Hillman reactions. Additionally, crystals of 1 undergo complete transmetalation with Cu(II) to afford isostructural 1. Moreover, the 2D framework of 1 allows replacement of urotropine molecules by 4,4'-azopyridine (azp) linker resulting in a three-dimensional (3D) metal-organic framework, {[Zn(L)(azp)]·4DMF 2HO} (2). The 1→2 transformation takes place in single-crystal-to-single crystal manner supported by powder X-ray diffraction, atomic force microscopy, high-resolution transmission electron microscopy, and morphological studies. Remarkably, during this 2D→3D transformation, the original trinuclear [Zn(COO)] secondary building unit changes to a mononuclear node, which is unprecedented.

“…Although these compounds are nonporous in nature, these materials showed significant capture of volatile iodine, which has been established with gravimetric uptake in the range 26.0–57.9 wt %. Besides, permanent porosity in 2D MOFs have also been exploited for the selectivity of different gas separations. , …”

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.
