“…Apart from compounds with π-bonded rings, carbaboranes and cluster compounds, there are only a few entries of such compounds in the Cambridge Structural Database [ 99 ]. These examples involve polymeric carboxylates [ 100 , 101 ], crown ethers or cryptands [ 102 ]. It should be mentioned that the latter compounds contain gallium in its oxidation state “+1”.…”

The controlled, self-assembled synthesis of multinuclear coordination compounds can be performed via different approaches. Frequently, steric, geometric and/or electronic factors located at the ligand systems predefine the way in which metal ions can assemble them to large aggregates. For the compounds in the present paper, also the Pearson’s acidities and preferred coordination geometries of the metal ions were used as organization principles. The ligand under study, 2,6-dipicolinoylbis(N,N-diethylthiourea), H2L1ethyl, possesses ‘soft’ sulfur and ‘hard’ nitrogen and oxygen donors. One-pot reactions of this compound with [AuCl(tht)] (tht = tetrahydrothiophene) and M3+ salts (M = Sc, Y, La, Ln, Ga, In) give products with gold-based {Au3(L1ethyl)3}3+ or {Au2(L1ethyl)2}2+ coronands, which host central M3+ ions. The formation of such units is templated by the M3+ ions and the individual size of the coronand rings is dependent on the ionic radii of the central ions in a way that small ions such as Ga3+ form a [Ga⊂{Au2(L1ethyl)2}]+ assembly, while larger ions (starting from Sc3+/In3+) establish neutral [M⊂{Au3(L1ethyl)3}] units with nine-coordinate central ions.

“… Furthermore, DFT calculations proved that the twisting of OPE rings in different solvent vapor resulted in the shift. Temperature and solvent modulated fluorescence is also noted in [M(2,2′-bpda)(1,4-bdc) 0.5 (phen)]·0.5H 2 O (M = Ga/In; 2,2′-H 2 bpda = 2,2′-biphenyldicarboxylic acid) …”

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.

“…Based on the indium-based MOF with the BTC (H 3 BTC = 1,3,5-benzenetricarboxylic acid) linker, namely, CPM-5 , a Cl-decorated derivative, CPM-5-Cl , has been reported . Indium MOFs with π-conjugated carboxylate ligands are usually fluorescent due to their strong In–O bonds, 4d 10 configuration of In 3+ , charged building blocks, and delocalized π-electron system, − whereas CPM-5-Cl shows promising applications in blue LEDs with strong emission at 425 nm upon photoexcitation, corresponding to a remarkable bathochromic shift with respect to the emission of free H 3 BTC at 332 nm (Figure a,b) . On the other hand, the yttrium-based MOF, [Y(BTC)(H 2 O) 6 ], has shown enhanced blue emission with an increase in the PLQY from 2.8% to 75.0% upon applying increasing amounts of pressure, followed by the release of pressure .…”

The exponential increase in the use of mobile phones and portable devices has led to a greater demand for cheap and lightweight yet efficient light-emitting diodes (LEDs). With the significant research interest in nanoporous organic frameworks, including metal−organic frameworks, covalent organic frameworks, and hydrogen-bonded organic frameworks (MOFs, COFs, and HOFs), their applications in electronics, and particularly as LEDs, have been growing. This review summarizes the main nanoporous MOFs, COFs, and HOFs applied as LEDs that have been reported in the past 10 years. The reported studies are mainly classified depending on the types of organic precursors involved, so as to provide insight into a predesignable approach for LEDs based on these types of nanoporous frameworks that can later be commercialized and integrated into the industry of mobile technology.
