“…To analyse the possible enhancement of photoluminescence via energy transfer among different lanthanide ions, [39] the mixedlanthanide MUV-5a(Yb0.76Er0.24) was synthesized and characterized (see Supporting Information). The excitation spectra of MUV-5a(Yb0.76Er0.24), MUV-5a(Er) and MUV-5a(Gd) compounds recorded at 295 K and 12 K ( Figure 5) display a broad band from 250 to ca.…”

Tetrathiafulvalene-Lanthanide (TTF-Ln) Metal-Organic Frameworks (MOFs) are an interesting class of multifunctional materials in which porosity can be combined with electronic properties such as electrical conductivity, redox activity, luminescence and magnetism. Herein we report a new family of isostructural TTF-Ln MOFs, denoted as MUV-5(Ln) (Ln = Gd, Tb, Dy, Ho, Er), exhibiting semiconducting properties as a consequence of the short intermolecular S···S contacts established along the chain direction between partially oxidised TTF moieties. In addition, this family shows photoluminescence properties and single-molecule magnetic behaviour, finding near-infrared (NIR) photoluminescence in the Yb/Er derivative and slow relaxation of the magnetisation in the Dy and Er derivatives. As such properties are dependent on the electronic structure of the lanthanide ion, we emphasise the immense structural, electronic and functional versatility of this class of materials.

“…1-3, 13, 18-21 Furthermore, by considering their diversity in chemical compositions and structural topologies, MOFs are considered as highly promising candidates for multifunctional materials for their potential application in gas absorption and separation, ionic exchange and identification, conductive and catalytic, magnetic and even ferroelectric properties. 4,22 In particular, some MOFs with perovskite topology showing the coexistence of ferroelectric and magnetic orders, such as AM II (HCOO)3 (A = NH2(CH3)2 (DMA) or NH4; M = Mg, Zn, Mn, Ni, Co, or Fe), 5-7, 18-21, 23-26 have been theoretically predicted and/or experimentally characterized. In these studies, it has been shown that the magnetic order originates from metal ions and the ferroelectric order from the organic molecules through a quite peculiar hybrid improper inversion symmetry breaking mechanism.…”

Density functional theory calculations have been performed for the structural, electronic, magnetic and ferroelectric properties of a mixed-valence Fe(II)-Fe(III) formate framework [NH2(CH3)2][Fe III Fe II (HCOO)6] (DMAFeFe). Recent experiments report a spontaneous electric polarization and our calculations are in agreement with the reported experimental value. Furthermore, we shed light into the microscopic mechanism leading to the observed value and as well how to possibly enhanced the polarization. The interplay between charge ordering, dipolar ordering of DMA + cations and the induced structural distortions suggest new interesting directions to explore in these complex multifunctional hybrid perovskites.

“…Metal-organic frameworks (MOFs) or porous coordination polymers (PCPs), constructed from organic ligands and inorganic building units (metal ions or clusters), are an intriguing class of coordination polymers [1][2][3]. There has been a substantial increase in interest of MOFs owing to their attractive physicochemical characteristics such as high surface area, permanent porosity, abundant active sites, and flexible chemical structure [4][5][6][7][8][9].…”

Water-based routes for synthesis of metal-organic frameworks: A review

et al. 2020

View full text Add to dashboard Cite

Although metal-organic frameworks (MOFs) show numerous advantages over other crystalline materials, their industrial relevances have been impeded owing to their many drawbacks such as environmental impacts and economic costs of their synthesis. A green preparation pathway could greatly reduce the environmental costs, energy, and the need for toxic organic solvents, and consequently reduce the production cost. Thus, the most desirable synthesis route is the replacement of harsh organic solvents with aqueous solutions to abate environmental and economic impacts. This review summarizes recent research advancements of water-based routes for MOF synthesis and gives a brief outline of the most prominent examples. The challenges and prospects of the commercialization of promising MOFs in the future are also presented. This study aims to offer necessary information regarding the green, sustainable, and industrially acceptable fabrication of MOFs for their commercial applications in the future.
