“…MIL-53-Fe with HF (MIL-53–Fe-F) was synthesized according to the procedure reported by Millange et al in 2010 40 and using the BDC ligand obtained from PET with our procedure reported in 2022. 9 The synthesis of MIL-53–Fe-F consists of dissolving FeCl 3 ·6H 2 O (0.2703 g) and BDC (0.1661 g) in 10 mL of DMF and 20 mg of 5 M HF. The mixture was heated at 150 °C for 48 h in a digestion pump (Teflon reactor with an internal volume of 60 mL).…”

“…By varying these building blocks, materials can be designed with different properties. Aromatic dicarboxylic acids are widely used as ligands in the synthesis of MOFs due to their excellent coordination properties. − These acids can be obtained from different sources, including waste bottles, − for example, polyethylene terephthalate (PET) bottles, and then the linker molecule, benzene 1,4-dicarboxylic acid (BDC, terephthalic acid), can be recovered by hydrolysis . Using materials from waste has gained significant importance in today’s economy.…”

This research focuses on developing MIL-53-type compounds with Fe obtained with ligands derived from PET waste, followed by the controlled addition of hydrofluoric acid (HF). Incorporating HF into the MOF structure induced substantial changes in the material textural properties, resulting in a significant change in CO 2 adsorption. Furthermore, a distinctive structural alteration (breathing effect) was observed in the CO 2 isotherms at different temperatures; these structural changes have not been observed by X-ray diffraction (XRD) because this characterization has been performed at room temperature, whereas the adsorption experiments were conducted at 260, 273, and 303 K and different pressures. Subsequently, DFT studies were performed to investigate the CO 2 -filling mechanisms and elucidate the material respiration effect. This approach offers promising opportunities for sustainable materials with improved gas adsorption properties.

“…Different research groups reported the preparation of other PET-derived-BDC MOFs containing Cu(II) [ 129–131 ], Zn(II) [ 132 ], Sn(II) [ 133 ], Ca(II) [ 134 ], Ba(II) [ 135 ], Ti(IV) [ 136 ], Co(II) and Ni(II) [ 137 ], as well as a lanthanide based (Tb) MOFs [ 138 ]. For all these MOFs, a two-step synthesis was proposed, where the BDC ligand was first produced from PET by either alkalosis, acidolysis, solvolysis or via a hydrothermal depolymerization with ethylene glycol.…”

Mismanagement of plastic waste results in its ubiquitous presence in the environment. Despite being durable and persistent materials, plastics are reduced by weathering phenomena into debris with a particle size down to nanometers. The fate and ecotoxicological effects of these solid micropollutants are not fully understood yet, but they are raising increasing concerns for the environment and people’s health. Even if different current technologies have the potential to remove plastic particles, the efficiency of these processes is modest, especially for nanoparticles. Metal-organic frameworks (MOFs) are crystalline nano-porous materials with unique properties, have unique properties, such as strong coordination bonds, large and robustus porous structures, high accessible surface areas and adsorption capacity, which make them suitable adsorbent materials for micropollutants. This review examines the preliminary results reported in literature indicating that MOFs are promising adsorbents for the removal of plastic particles from water, especially when MOFs are integrated in porous composite materials or membranes, where they are able to assure high removal efficiency, superior water flux and antifouling properties, even in the presence of other dissolved co-pollutants. Moreover, a recent trend for the alternative preparation of MOFs starting from plastic waste, especially polyethylene terephthalate, as a sustainable source of organic linkers is also reviewed, as it represents a promising route for mitigating the impact of the costs deriving from the widescale MOFs production and application. This connubial between MOFs and plastic has the potential to contribute at implementing a more effective waste management and the circular economy principles in the polymer life cycle.

“…Selective incorporation of different metal cations requires a specific ligand design. While conventional ligands for CPs usually feature two or more equivalent coordinating groups in spatially separated positions, like for example in terephthalate, , a heterometallic CP requires a heterofunctional ligand. The coordinating groups may on the one hand differ in their Pearson hardness allowing preferred interaction with matching metal cations. , Alternatively, coordinating groups can be selectively activated by deprotonation.…”

A Rigid Linker for Site-Selective Coordination of Transition Metal Cations: Combining an Acetylacetone with a Caged Phosphine

The combination of a soft phosphorus and a hard oxygen donor in the new ligand HacacTRIP leads to excellent site selectivity for the coordination of two different metal cations of matching Pearson character. The deprotonation step required for coordinating the acetylacetone oxygen donor further increases the selectivity. In contrast to most phosphines, the use of the caged phosphatriptycene motif enables a rigid and directional orientation of the phosphorus binding site which is required to form stable coordination network structures. In addition to the synthesis of HacacTRIP, we present its selective coordination. The deprotonated acetylacetone was selectively bound to CuII and FeIII. The solid state structure of the former displays a rare axial coordination of chloroform molecules. The phosphorus donor was selectively coordinated to the monovalent coinage metal cations CuI, AgI, and AuI. The CuI and AgI complexes represent the first examples in which a phosphatriptycene is bound to these metal cations. Heterometallic coordination compounds were characterized with combinations of these two groups. They comprise an oligonuclear CuI/CuII mixed-valence compound in which iodide binds to both CuI and CuII cations and a complex in which acacTRIP– bridges CuII and AuI. In addition to these discrete aggregates, the ligand has been used to link FeIII and AgI into a 2D coordination polymer with unprecedented trigonal planar coordination of three bulky phosphatriptycenes to a cation and resulting honeycomb topology. Its almost regular hexagons underline the desired rigidity of the ditopic acacTRIP– ligand.
