Saadatkish, Niloufar;Karimi-Sabet, Javad;Sharif, Alireza research published 《 A molecular dynamics simulation study on the solubilities of monomers of a PIM-1 polymer in supercritical carbon dioxide》, the research content is summarized as follows. The absolute solubilities of tetrahydroxy-3,3,3′,3′-tetramethyl-1,1′-spirobisindane (TTSBI) and tetrafluoroterephthalonitrile (TFTPN), the monomers of a polymer of intrinsic microporosity-1 (PIM-1), in supercritical carbon dioxide (SCCO₂), are studied by mol. dynamics (MD) simulation method. Solvation free energies of the monomers in SCCO₂ are simulated at different temperatures and pressures by the thermodn. integration method. Furthermore, a new procedure is proposed to calculate the external pressure dependency of the monomers vapor pressures by MD simulation. These two quantities are used to estimate the absolute solubility of each monomer in SCCO₂ medium. TFTPN showed higher solubility (than TTSBI) which was ascribed to its CO₂-philic structure and low vapor pressure. Exptl. measured solubilities are in good agreement with the simulated ones confirming the accuracy of the proposed method for the calculation of vapor pressures. Finally, SCCO₂ medium is suggested as a suitable medium for synthesis of PIM-1 polymer provided that small amounts of a cosolvent are used or high external pressures (greater than 30 MPa) are applied.

Ruengsangtongkul, Sureeporn;Kuribara, Takahito;Chaisan, Nattawadee;Tummatorn, Jumreang;Thongsornkleeb, Charnsak;Ruchirawat, Somsak research published 《 Ceric Ammonium Nitrate Promoted Oxidative Coupling of Terminal Alkynes and 1,3-Keto Esters: A Synthesis of Unsymmetrical 1,1,2-Triacylalkenes》, the research content is summarized as follows. Unsym. 1,1,2-triacylalkenes were conveniently prepared by the oxidative coupling of 1,3-keto esters with terminal alkynes by employing 4.0 equiv of inexpensive ceric ammonium nitrate (CAN) as the oxidant in acetonitrile as the solvent at 0 °C. The method is milder than previously reported methods and can be conducted under air, thereby demonstrating its practicality and versatility for preparing these useful building blocks. The reaction was believed to occur by a single-electron-transfer process of the 1,3-keto ester substrate initiated by CAN to generate an α-radical species that quickly added to the terminal alkyne partner in the reaction. Subsequent oxidation of the resulting vinyl radical by air and CAN then lead to the formation of the triacylalkene product as a mixture of E- and Z-isomers. The reaction was shown to be general, with 27 illustrative examples of the formation of the desired products in up to quant. yield and with moderate to excellent alkene geometrical selectivities.

The inhibition capacity of carbon steel (CS) in 0.5M H₂SO₄ by three 8-hydroxyquinoline grafted triazole derivatives (EHTC, AHTC, and MHTC) have been investigated using electrochem. impedance spectroscopy (EIS), potentiodynamic polarization (PPD), and weight loss measurements (WLM) at 298 K. Generally, the results clearly show that the inhibition performance (η %) increases with an increase in the concentration of EHTC, MHTC, and AHTC, reaching a maximum value of 95.5% (EHTC), 95.1% (MHTC), and 94.1% (AHTC) at the optimal concentration (10^-3 M) for PPD tech. The PPD shows that EHTC, AHTC, and MHTC behave as mixed-type inhibitors. In addition, the inhibitor obeys the single layer adsorption isotherm of Langmuir. SEM (SEM) anal. of the CS has also been investigated and discussed. The theor. calculations and MD simulations show a better correlation with the exptl. results for the studied triazole derivatives

Rong, Siyi;Su, Pengcheng;Chen, Shizheng;Jia, Miaomiao;Li, Wanbin research published 《 Sub-5 nm porous polymer decoration toward superhydrophobic MOFs with enhanced stability and processability》, the research content is summarized as follows. Metal-organic frameworks (MOFs) show great potential for various applications, but many of them suffer from the drawbacks of hydrolysis propensity and poor processability. Herein, we employ polymers of intrinsic microporosity (PIMs) with hydrophobic pores to decorate MOFs toward substantially improved water stability and shapeability. Through simple PIM-1 decoration, the sub-5 nm polymer layers can be uniformly deposited on MOF surfaces with almost no deterioration in porosity. Owing to the existence of superhydrophobic coating and the obstruction of water entrance into MOFs, the PIM-1 coated CuBTC exhibits impressive water resistance and excellent pore preservation ability after exposure in water, even in acidic and alk. solutions Moreover, polymer decoration improves the processability of MOFs, while various MOF/PIM-1 bulk wafers and oil-water separators can be obtained straightforwardly.

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.
