Wang, Zijie;Chen, Hongni;Gao, Xing;Hu, Bo;Meng, Qingli;Zhao, Chuanliang;Yang, Liwei;Zheng, Huaili research published 《 A novel self-floating cyclodextrin-modified polymer for cationic dye removal: Preparation, adsorption behavior and mechanism》, the research content is summarized as follows. The separation and recycling processes of current cyclodextrin (CD)-based adsorbents are complicated. Thus, a novel composite based on a large surface area, porous, and self-floating tetrafluoroterephthalonitrile (TFN)-crosslinked CD polymer (FTFCD), was fabricated, characterized and applied to treat cationic dye pollutants. The characterization showed a porosity, good thermal stability, a stable crystal structure, and abundant functional groups on the prepared FTFCD, which had demonstrated great improvement on its adsorption capacity towards attention grabbing pollutants. The removal efficiency of the adsorbents for malachite green (MG) remained above 95% at pH 1 ∼ 10. In addition, the adsorbents were found to rapidly reach equilibrium governed by the pseudo-second-order kinetic model, and the maximum adsorption capacity of FTFCD was 1390.263 mg/g, as corroborated by the Langmuir isotherm model. While the phenolate groups of FTFCD found to electrostatically interacts with the MG strong cationic quaternary amine group, hydrogen-bonding was responsible for the hydroxyl group of FTFCD and the quaternary amine group binding. Meanwhile, the triangular cone configuration of MG makes it easy to be entrapped and absorbed in the hydrophobic cavity. Besides, after regeneration of exhausted FTFCD for five successive cycles, the MG removal efficiency still reached more than 80%. Thus, FTFCD could be applied as a potential alternative adsorbent for cationic dye removal owing to its excellent adsorption performance, convenient recycling, wide pH application, and environmental friendliness.

Wang, Liang;Guo, Xiang;Zhang, Feng;Li, Nanwen research published 《 Blending and in situ thermally crosslinking of dual rigid polymers for anti-plasticized gas separation membranes》, the research content is summarized as follows. The polybenzimidazoles (PBI) has been employed as blends and macromol. crosslinkers into bromomethylated polymers of intrinsic microporosity (PIM-Br) to prepare anti-plasticized gas separation membrane. Interestingly, the PBI showed excellent miscibility with PIM-Br probably due to the interaction between the benzimidazole and -CN groups, and thus a series of flexible, tough and transparent membranes were obtained by simply blending. After thermal treatment of the blending membrane, the crosslinked PIM-Br/PBI membranes with ionic and covalent crosslinking were achieved as confirmed by XPS results. Although the blending PIM-Br/PBI membranes showed the decreased gas permeabilities due to the lower gas permeability of PBI moieties, the increased gas permeabilities of PIM-Br/PBI membrane has been observed after crosslinking without significant sacrificing of selectivity. Moreover, higher crosslinking temperature induced the higher gas permeability. The PIM-Br/PBI membrane having PBI content of 5 wt% treated at 300°C has a CO₂ permeability of 3313.7 Barrer which is much higher than that of the PIM-Br/PBI blending membrane (1645.3 Barrer) probably due to the formation of more open matrix in membrane after crosslinking. However, comparable CO₂/CH₄ selectivity of ∼13 were observed for all of the crosslinked membranes. Importantly, both of the blending and thermal crosslinking between PIM-Br and PBI resulted in the excellent CO₂ anti-plasticization ability of the membrane. Particularly, a single gas plasticization pressure as high as more than 600 psi and mixed-gas plasticization resistance for crosslinked PIM-Br/PBI have been observed This value is much higher than that of the pristine PIM-Br membrane (100 psi).

Tu, Poyi;He, Xunming;Abu-Reziq, Raed;Pan, Chunyue;Tang, Juntao;Yu, Guipeng research published 《 Fluorinated covalent triazine frameworks for effective CH₄ separation and iodine vapor uptake》, the research content is summarized as follows. In this article, analogous covalent triazine framework (CTFs) were simply prepared through the trimerization of different nitrile building blocks (tetrafluoroterephthalonitrile or terephthalonitrile) under typical ionothermal conditions. We demonstrated that the fluorine contents could be simply altered by changing the comonomer compositions Introducing fluorine could adjust the pore size distribution and electron structure of the network effectively. By increasing fluorine contents, an enhanced CO₂/CH₄ selectivity up to 15.5 was presented. Addnl., electron-concentrated fluorine strengthened CH/π interactions between the polymeric matrixes and guest CH₄, offering a CH₄/N₂ selectivity up to 8.0. The obtained CTFs also exhibited noticeable iodine adsorption capacity in vapor phase (302 wt%) due to their abundance of heteroatoms and porosity. These results clearly demonstrated the promising aspect of introducing fluorine groups into the porous networks for developing efficient sorbent towards potential applications in separating methane gas or iodine vapors and also affording further insight into the development of high performance functional polymers.

Ueda, Masahiro;Kimura, Masaki;Miyagawa, Shinobu;Naito, Masaya;Takaya, Hikaru;Tokunaga, Yuji research published 《 Four- and two-armed hetero porphyrin dimers: their specific recognition and self-sorting behaviours》, the research content is summarized as follows. In this study we self-assembled the four-armed porphyrin hetero dimer capsule Cap4, stabilized through amidinium-carboxylate salt bridges, in CH₂Cl₂ and CHCl₃. The dimer capsule Cap4 was kinetically and thermodynamically more stable than the corresponding two-armed dimer Cap2. The number of arms strongly influenced their recognition behavior; guests possessing small aromatic faces (e.g., 1,3,5-trinitrobenzene) preferred residing in the cavity of the two-armed capsule Cap2, rather than in Cap4, both thermodynamically and kinetically; in contrast, large aromatic guests (e.g., 9,10-dibromoanthracene) were encapsulated predominantly by Cap4 because of favorable entropic effects. The number of arms enabled self-sorting behavior of the dimer formation; complexation studies using an equimolar mixture of the four porphyrin constituents of the two capsules revealed the quant. formation of the corresponding dimers Cap2 and Cap4. Furthermore, we examined the specific mol. recognition of Cap2 and Cap4; NMR experiments of mixtures of Cap2 and Cap4 in the presence of favorable guests for Cap2 and Cap4 revealed that these guest mols. were encapsulated selectively by their preferred hosts.

Voon, Boon Kee;Shen Lau, Hui;Liang, Can Zeng;Yong, Wai Fen research published 《 Functionalized two-dimensional g-C₃N₄ nanosheets in PIM-1 mixed matrix membranes for gas separation》, the research content is summarized as follows. The virtuous of two-dimensional (2D) nanomaterials in high aspect ratio and tunable surface functionality have geared towards their implementation in mixed matrix membranes (MMMs) for advanced gas separation In this study, the effects of functionalized 2D nanosheets in the MMMs for gas separation were investigated. The graphitic carbon nitride (g-C₃N₄) nanosheets were modified with various functional groups namely sulfuric acid group, aliphatic amino group, aromatic amino group, and sulfonic group via four different synthesis approaches. Polymers of intrinsic microporosity (PIMs, e.g., PIM-1) was selected as the continuous polymer phase due to its intrinsic high permeability and comparable selectivity towards different gas pair. The sulfonic acid functionalized g-C₃N₄ MMMs (e.g., PIM-1/g-C₃N₄-D) imparted high separation properties ascribed to the great CO₂ affinity induced by the sulfonic acid groups. In particular, PIM-1/g-C₃N₄-D (99:1) MMM demonstrated promising CO₂ separation performance, with CO₂ permeability of 3740 Barrer and CO₂/N₂ selectivity of 19.8. Moreover, at 5 wt% loading of g-C₃N₄-D, the H₂/N₂ and O₂/N₂separation of the MMMs had exceeded the 2008 Robeson upper bound, thanks to the periodic triangular ultramicropores in g-C₃N₄ that favor precise sieving of small gases. These results pave the way in using the developed membranes in practical H₂ purification, air separation and CO₂ capture.

Wan, Jingmeng;Nian, Mengjie;Yang, Chao;Ge, Kai;Liu, Junjie;Chen, Zhiquan;Duan, Jingui;Jin, Wanqin research published 《 Interface regulation of mixed matrix membranes by ultrathin MOF nanosheet for faster CO₂ transfer》, the research content is summarized as follows. Mixed matrix membranes (MMMs) incorporating porous materials received extensive attention for applications of gas separation, but the one shows significant high permeability and increased selectivity is rare. Here, we report a strategy of interface regulation in two groups of MMMs via formed H-bonding by a newly designed and ultrathin metal organic framework nanosheet (MOFN). The chem. stable MOFN (thickness: 5-8 nm) with lamellae of micrometre lateral dimensions was prepared from [Hf₆] cluster and tricarboxylate ligand, where the capping mol. of formic acid coordinates with Hf⁴⁺ ion as H-bonding donor toward incorporated polymers and also acts as an anisotropic regulator for MOFN growth. The well-distributed MOFN in two polymers shows sharply promoted CO₂ permeability (720 GPU and 2085 GPU), as well as enhanced separation factor, over wide pressure and temperature ranges that are suitable for CO₂ capture from natural gas. This is because the H-bonding regulated polymer-MOFN alignments lead to contractile channel and abundant porosity, validated by Raman mapping and positron annihilation lifetime spectroscopy. This work not only gives rise two candidate membranes for selective CO₂ removal from naturals gas, but also, more prospectively, deliveries a design philosophy for construction of advanced MMMs.

Wang, Han;Zhao, Lu;Tang, Xuxu;Lv, Li-Ping;Sun, Weiwei;Wang, Yong research published 《 Functionalized graphene quantum dots modified dioxin-linked covalent organic frameworks for superior lithium storage》, the research content is summarized as follows. Covalent organic framework, as an emerging porous nano-frame structure with pre-designed structure and custom properties, has been demonstrated as a prospective electrode for rechargeable Li-ion batteries. For improving the reversible capacity and long-term cycle stability of COF materials, we propose a GQDs modified COF material (COF-GQDs) and apply it as the anode for LIBs for the first time. This COF-GQDs electrode delivers enhanced long-term cycling performance with a large capacity of ∼820 mAh g^-1 after 300 cycles at 100 mA g^-1 and an improved rate performance. The enhanced lithium-storage performance, in terms of obvious-shortened activation process and high reversible capacities, can be attributed to the modification of carboxyl GQDs, which would activate more active sites (activated C=C groups from benzene rings) for lithium-storage, and provide fast lithium-ion transportation kinetic. Besides, the decreased interphase resistance, enhanced electronic conductivity, and prevented aggregation of needle-flake COF structure, originated from the addition of GQDs, which lead to the enhanced improved cycling stability of the COF-GQDs electrode. This manuscript can promote the further exploration on the design of COF-related materials with modification of functionalized carbonaceous materials to achieve enhanced lithium-storage properties for next-generation energy storage.
