Han, Weiyao;Zhang, Caili;Zhao, Min;Yang, Fan;Yang, Yang;Weng, Yunxuan research published 《 Post-modification of PIM-1 and simultaneously in situ synthesis of porous polymer networks into PIM-1 matrix to enhance CO₂ separation performance》, the research content is summarized as follows. Post-modification of the chem. structures can be used to tailor the properties of polymers of intrinsic microporosity (PIM-1), which shows promise for application of PIM-1 gas separation membrane. Methane sulfonic acid (MSA) is capable of hydrolyzing and crosslinking nitrile groups of PIM-1 to form carboxylic acid-contained and triazine groups crosslinked PIM-1 (cPIM-1), and simultaneously catalyze in situ synthesis of porous polymer networks (PPNs) in PIM-1 matrix. These reactions were carried out at the same time by a one-step method. Characterization of hydrolysis and crosslinking process of nitrile groups in PIM-1 was performed by ATR, XPS, solubility, and ¹H NMR anal. MSA catalyzed synthetic approach of PPNs includes the trimerization of three acetyl groups and involves a coupled process of polymerization and membrane architecture formation. Finally, the process of crosslinking and hydrolysis can provide enhanced gas pair selectivity of PIM-1 membrane (cPIM-1) while the gas permeability of the membranes (cPIM-1/PPNs) can be increased by the incorporation of PPNs microstructure networks. As a result, the optimal cPIM-1/PPNs showed Roberson’s 2008 upper bound separation performance for CO₂/CH₄ and CO₂/N₂. The cPIM-1/PPN2-3% membrane demonstrated the best CO₂ comprehensive separation performance with the permeability of almost 11511 Barrer, with ideal selectivity of 24.3 and 22.2 for CO₂/N₂ and CO₂/CH₄ resp. Furthermore, the cPIM-1/PPNs membranes show excellent anti-aging properties. This indicates that MSA-catalyzed hydrolysis, crosslinking and in situ synthesis PPNs can effectively adjust the topol. structure of PIM-1 membrane for CO₂ separation

Han, Xiaocui;Chen, Liyuan;Wang, Yan;Wang, Tianjiao;Cui, Fengchao;Jiang, Zhenhua;Pang, Jinhui research published 《 Novel Polymers with Ultrapermeability Based on Alternately Planar and Contorted Units for Gas Separation》, the research content is summarized as follows. Polymers of intrinsic microporosity (PIMs) have been the potential candidates as gas separation membrane materials, because of their high permeability and good processing. Here, three PIMs (PIM-ABAs) with ultrahigh permeability are reported; these are significantly more permeable than the PIM-1 and other PIMs reported and do not lose high selectivity and good processing merit. The introduction of large and rigid planar units alternatively contorted units suppresses the compact packing of polymer chains, resulting in the hierarchical porosity range of 0.5-4.0 nm. The presence of larger pores is responsible for promoting permeability. PIM-ABA-OMEN demonstrates the optimal CO₂ permeability (16 736 barrer), which is 3.95 times more than PIM-1 (4234 barrer) with equivalent gas selectivity and PIM-ABA-EN exhibits the promotion of both permeability and selectivity. After being aged for 186 days, PIM-ABAs still showed the CO₂ permeability above 8000 barrer, which is almost as 2 times greater than that of unaged PIM-1. This work provides a new strategy for the preparation of PIMs with enhanced gas separation performance.

To overcome the trade-off between permeability and selectivity of polymeric membranes and understand the influence of ultra-rigid units on gas separation performance, a series of PIMs (PIM-EN-x) based on spirodifluoranthene (EN) have been prepared These polymers showed outstanding thermal stability. Their 5% weight loss temperature is higher than 503°C. PIM-EN-x owned high BET surface area, ranging from 804 to 895 m² g^-1. With the increase of EN units, the gas permeability increased. The CO₂ permeability of PIM-EN-40 is 11512 barrer, which is increased by 172% compared to PIM-1 with no loss in selectivity. The gas separation performance of PIM-EN-x surpassed the 2008 upper bound and near the latest upper bound. This work put forward a special structural unit to prepare polymers for CO₂ separation and natural gas sweetening.

He, Shanshan;Zhu, Bin;Jiang, Xu;Han, Gang;Li, Songwei;Lau, Cher Hon;Wu, Yadong;Zhang, Yanqiu;Shao, Lu research published 《 Symbiosis-inspired de novo synthesis of ultrahigh MOF growth mixed matrix membranes for sustainable carbon capture》, the research content is summarized as follows. Mixed matrix membranes (MMMs) are one of the most promising solutions for energy-efficient gas separation However, conventional MMM synthesis methods inevitably lead to poor filler-polymer interfacial compatibility, filler agglomeration, and limited loading. Herein, inspired by symbiotic relations in nature, a universal bottom-up method is designed for in situ nanosized metal organic framework (MOF) assembly within polymer matrixes. Consequently, the method eliminating the traditional postsynthetic step significantly enhanced MOF dispersion, interfacial compatibility, and loading to an unprecedented 67.2 weight% in synthesized MMMs. Utilizing exptl. techniques and complementary d. functional theory (DFT) simulation, it is validated that these enhancements synergistically ameliorated CO₂ solubility, which was significantly different from other works where MOF typically promoted gas diffusion. The approach simultaneously improves CO₂ permeability and selectivity, and superior carbon capture performance is maintained even during long-term tests; the mech. strength is retained even with ultrahigh MOF loadings. This symbiosis-inspired de novo strategy can potentially pave the way for next-generation MMMs that can fully exploit the unique characteristics of both MOFs and matrixes.

Geng, Chenxu;Sun, Yuxiu;Zhang, Zhengqing;Qiao, Zhihua;Zhong, Chongli research published 《 Mitigated Aging in a Defective Metal-Organic Framework Pillared Polymer of an Intrinsic Porosity Hybrid Membrane for Efficient Gas Separation》, the research content is summarized as follows. Although polymers of intrinsic microporosity (PIMs) were recognized as highly permeable membrane materials in gas separation, the phys. aging phenomenon seriously affected their performance due to the collapse of micropores. In this work, we report an alternative approach to alleviate the phys. aging of PIM-based membranes, as demonstrated by pillaring the PIM-1 membrane with defect-engineered metal-organic framework (MOF) nanoparticles. With excellent interfacial compatibility between the defective UiO-66-FA and PIM-1 by the formation of hydrogen-bond networks, the incorporated MOF nanoparticles acted as pillars of the resulting mixed matrix membranes (UiO-66-FA/PIM-1 MMM) to prevent the collapse of the micropores of the PIM-1 membrane and hence reduce its aging. Concurrently, defective MOFs in the polymer matrix endow the resulting MMMs with fast diffusion pathways and facilitate CO₂ transport. Compared with the pristine PIM-1 membrane, UiO-66-FA/PIM-1 MMM displayed maintained CO₂/N₂ selectivity of about 23.1 but a sharp increased CO₂ permeability from 3980 to 16,591 barrer. Only a 25% reduction in CO₂ permeability was observed for the UiO-66-FA/PIM-1 MMM after 160 days of operation under the mixed-gas CO₂/N₂ separation conditions, which is less than the equivalent losses of 40 and 76% for the counterpart MOF-based hybrid membrane and PIM-1, resp. Given that the performances of the resulting membranes far surpass the 2008 Robeson upper bound, this study may provide a feasible way for sustainable development of PIM-based MMMs in gas separation application.

Gkika, Despina A.;Filiz, Volkan;Rangou, Sofia;Kyzas, George Z.;Mitrοpoulos, Athanasios C. research published 《 Cost Profile of Membranes That Use Polymers of Intrinsic Microporosity (PIMs)》, the research content is summarized as follows. Assessing the financial impact of polymers of intrinsic microporosity, otherwise known as PIMs, at the lab scale has been impeded by the absence of a holistic approach that would envelop all related financial parameters, and most importantly any indirect costs, such as laboratory accidents that have been consistently neglected and undervalued in past assessments. To quantify the cost of PIMs in relation to the risks befalling a laboratory, an innovative cost evaluation approach was designed. This approach consists of three stages. Firstly, a two-fold “window of opportunity” (WO) theory is suggested, dividing the total cost profile into two segments, followed up by a qual. risk anal. to establish the potential cost components. The last stage builds on a total cost of ownership model, incorporating the two types of WO. The total cost of ownership (TCO) approach was selected to ascertain the costs and construct the cost profile of PIMs, according to laboratory exptl. data. This model was applied to the synthesis and physicochem. characterization processes. The quant. anal. revealed that the most influential parameters for synthesis are accidents and energy costs. This is in contrast with the physicochem. characterization process, where the most important determinant is the energy cost.

Gong, Jun;Huang, Ruishan;Wang, Chunfei;Zhao, Zujin;Tang, Ben Zhong;Zhang, Xuanjun research published 《 Circularly polarized luminescent 4,4′-bicarbazole scaffold for facile construction of chiroptical probes》, the research content is summarized as follows. Small mols. with circularly polarized luminescence (CPL) are especially valuable in solution-based applications, like chiroptical probes for effective sensing. Such application was not well explored due in part to hard introduction of appropriate triggerable fluorophores. An easily post-modifiable CPL-active scaffold (4) is reported, and a feasible strategy to construct chiroptical probes for sensing hypochlorous acid is further proposed. Helically chiral 4 with a 4,4′-bicarbazole scaffold exhibits a large Stokes shift ≤142 nm and g_lum value of 0.9 × 10^-3. Through facile construction of phenothiazine moiety on 4, red-emitting compound 5 was obtained in high yield (85.3%), showing distinct optical and chiroptical responses towards hypochlorous acid with good liner relations and CPL sign blue-shifting of 120 nm in vitro. The probe is also applied to detect endogenous hypochlorous acid in living macrophages and can serve as a CPL sensor. Taking 5 as an application example, the authors envision that CPL-enabling scaffold 4 could find broad use in the design of more chiroptical probes.
