Rochat, Sebastien;Tian, Mi;Atri, Ria;Mays, Timothy J.;Burrows, Andrew D. research published 《 Enhancement of gas storage and separation properties of microporous polymers by simple chemical modifications》, the research content is summarized as follows. Owing to their large surface area and good solvent processability, polymers of intrinsic microporosity (PIMs) have been widely investigated for gas storage and separation processes. In this article, we show how chem. modifying the polymers can fine-tune their properties for specific, targeted applications. We find that converting the archetypal microporous polymer PIM-1 into a polycarboxylate salt enhances its separation capabilities for H₂/CO₂ mixtures (relevant to hydrogen production), whereas appending multiple amine groups significantly improves gas separation properties for N₂/CO₂ mixtures (relevant to flue gas treatment). Adsorption-based separation processes have received less attention than size-sieving processes in porous polymeric materials, however they could provide a suitable alternative technol. to energy-intensive separation processes such as cryogenic distillation We also report the hydrogen storage properties of the modified polymers, which we find to depend on the chem. modification carried out. By coupling the simplicity of the proposed chem. modifications with the scalability and porous properties of PIMs, we provide a blueprint to create new multifunctional materials with adapted properties for targeted applications.

Ricci, Eleonora;Benedetti, Francesco M.;Noto, Antonella;Merkel, Timothy C.;Jin, Jianyong;De Angelis, Maria Grazia research published 《 Enabling experimental characterization and prediction of ternary mixed-gas sorption in polymers: C₂H₆/CO₂/CH₄ in PIM-1》, the research content is summarized as follows. In this work, a new exptl. protocol was designed to measure sorption of ternary gas mixtures in polymer membranes for the first time. We measured the sorption isotherms of binary and ternary mixtures of C₂H₆, CO₂, and CH₄ in PIM-1, using a pressure decay apparatus, working at constant composition and variable pressure of the gas phase. The results show competitive sorption effects in all gas mixtures analyzed, affecting each species in proportion to the total sorbed concentration of the other components. It was found that the presence of C₂H₆ in the mixture reduces the sorption of both CH₄ and CO₂ to a similar extent, so that the CO₂/CH₄ solubility-selectivity is not markedly affected. The exptl. data were used to validate predictions of the Non-Equilibrium Lattice Fluid (NELF) model of binary and ternary sorption isotherms. The NELF model is generally in close agreement, both in the prediction of pressure and mixture composition effects, proving to be a reliable tool to assess mixed-gas sorption, even in complex scenarios.

Quintavalla, Arianna;Veronesi, Ruben;Speziali, Laura;Martinelli, Ada;Zaccheroni, Nelsi;Mummolo, Liviana;Lombardo, Marco research published 《 Allenamides Playing Domino: A Redox-Neutral Photocatalytic Synthesis of Functionalized 2-Aminofurans》, the research content is summarized as follows. A photoredox catalytic synthesis of functionalized 2-aminofurans I [R = OPh, 2-oxooxazolidin-3-yl, indol-1-yl, etc.; R¹ = Me, Ph, 2-thienyl, etc.; R² = H, Me, CO₂Et, etc.] was proposed starting from α-halo carbonyl substrates and N-allenamides. The use of visible light as green energy source, redox-neutral nature of the transformation allowing to avoid additives and strong oxidants, mild reaction conditions and the functional groups tolerance, low photocatalyst loading and the absence of excess reagents, one-pot formation of three new bonds in a domino sequence, these features of this protocol made it particularly efficient and sustainable. According to mechanistic hypothesis, the transformation was configured as a double radical-polar crossover reaction, in which the photocatalyst was excited, oxidized and reduced twice for each mol. of 2-aminofuran produced. The novelty of the designed synthetic approach also lied in the use of N-allenamides as substrates, which, after the addition of the first electrophilic radical, preserve a further reactive π-system, made possible the addition of a second α-keto radical and enabling the installation of a keto functionality at a remote position. The good yields, broad scope and possibility to further synthetically elaborate the obtained furans made this protocol particularly promising for the construction of useful products.

In this work, thin film nanocomposite (TFN) membranes of super-glassy polymer PIM-1 containing zeolitic imidazolate framework-8 (ZIF-8)/graphene oxide (GO) composites (ZG) have been prepared by dip-coating onto water pre-impregnated polyvinylidene fluoride (PVDF) substrates. Higher flux and improved separation factors as compared to bare PIM-1 thin film composite (TFC) membranes have been achieved in organophilic pervaporation; for an aqueous feed solution with 5 wt% of butanol at 65°C, a total permeate flux of 7.9 ± 0.69 kg m-²h^-1 and a separation factor (β_BtOH/H2O) of 29.9 ± 1.99 have been obtained with a TFC membrane containing 0.5 wt% of ZG filler. The pervaporation separation index (PSI) of this membrane (228 kg m^-2h^-1) is amongst the highest values reported in the literature. This excellent performance is attributed to the formation of a defect-free PIM-1 active layer (<1μm) and the hydrophobic nature of the ZG fillers.
