Yan, Zhi-Ping;Liu, Ting-Ting;Wu, Ruixia;Liang, Xiao;Li, Zhi-Qiang;Zhou, Liang;Zheng, You-Xuan;Zuo, Jing-Lin research published 《 Chiral Thermally Activated Delayed Fluorescence Materials Based on R/S-N²,N²′-Diphenyl-[1,1′-binaphthalene]-2,2′-diamine Donor with Narrow Emission Spectra for Highly Efficient Circularly Polarized Electroluminescence》, the research content is summarized as follows. In this study, two pairs of chiral thermally activated delayed fluorescence (TADF) materials enabling circularly polarized luminescence (CPL) named R/S-p-BAMCN (rod-shape) and R/S-o-BAMCN (helix-shape) are prepared based on a new pair of chiral donor (D*), R/S-N2,N2′-diphenyl-[1,1′-binaphthalene]-2,2′-diamine (R/S-BAM), and two cyano (CN) acceptors. Due to the rigid mol. structure and special intramol. arrangement, the chiral TADF materials show high photoluminescence quantum efficiency (up to 0.86) with narrow full-width at half-maximum (38 nm in cyclohexane, 51 nm in toluene) and photoluminescence dissymmetry factor (|gPL|) up to 5.3 x 10^-3. Particularly, the circularly polarized OLEDs (CP-OLEDs) with rod-shaped R/S-p-BAMCN as the emitter show high device performances with the maximum external quantum efficiency nearing 28%. Meanwhile, the semi-transparent CP-OLEDs based on helix-shaped R/S-o-BAMCN exhibit obvious circularly polarized electroluminescence (CPEL) properties with the electroluminescence |gEL| factors around 4.6 x 10-3. The strategy of rigid D*-A-D* structure with special arrangement of chiral donor provides a direct way to obtain efficient CP-TADF materials with narrow emission spectra and promising CPL properties for better CPEL performance.

Yang, Chongqing;Jiang, Kaiyue;Zheng, Qi;Li, Xinle;Mao, Haiyan;Zhong, Wenkai;Chen, Cheng;Sun, Bing;Zheng, Haimei;Zhuang, Xiaodong;Reimer, Jeffrey A.;Liu, Yi;Zhang, Jian research published 《 Chemically stable polyarylether-based metallophthalocyanine frameworks with high carrier mobilities for capacitive energy storage》, the research content is summarized as follows. Covalent organic frameworks (COFs) with efficient charge transport and exceptional chem. stability are emerging as an import class of semiconducting materials for opto-/electronic devices and energy-related applications. However, the limited synthetic chem. to access such materials and the lack of mechanistic understanding of carrier mobility greatly hinder their practical applications. Herein, we report the synthesis of three chem. stable polyarylether-based metallophthalocyanine COFs (PAE-PcM, M = Cu, Ni, and Co) and facile in situ growth of their thin films on various substrates (i.e., SiO₂/Si, ITO, quartz) under solvothermal conditions. We show that PAE-PcM COFs thin films with van der Waals layered structures exhibit p-type semiconducting properties with the intrinsic mobility up to ~19.4 cm² V^-1 s^-1 and 4 orders of magnitude of increase in conductivity for PAE-PcCu film (0.2 S m^-1) after iodine doping. D. functional theory calculations reveal that the carrier transport in the framework is anisotropic, with the out-of-plane hole transport along columnar stacked phthalocyanine more favorable. Furthermore, PAE-PcCo shows the redox behavior maximumly contributes ~88.5% of its capacitance performance, giving rise to a high surface area normalized capacitance of ~19 μF cm^-2. Overall, this work not only offers fundamental understandings of electronic properties of polyarylether-based 2D COFs but also paves the way for their energy-related applications.

A.;Kucernak, Anthony R.;Jelfs, Kim E.;McKeown, Neil B.;Song, Qilei research published 《 Development of efficient aqueous organic redox flow batteries using ion-sieving sulfonated polymer membranes》, the research content is summarized as follows. Redox flow batteries using aqueous organic-based electrolytes are promising candidates for developing cost-effective grid-scale energy storage devices. However, a significant drawback of these batteries is the cross-mixing of active species through the membrane, which causes battery performance degradation To overcome this issue, here we report size-selective ion-exchange membranes prepared by sulfonation of a spirobifluorene-based microporous polymer and demonstrate their efficient ion sieving functions in flow batteries. The spirobifluorene unit allows control over the degree of sulfonation to optimize the transport of cations, while the microporous structure inhibits the crossover of organic mols. via mol. sieving. Furthermore, the enhanced membrane selectivity mitigates the crossover-induced capacity decay while maintaining good ionic conductivity for aqueous electrolyte solution at pH 9, where the redox-active organic mols. show long-term stability. We also prove the boosting effect of the membranes on the energy efficiency and peak power d. of the aqueous redox flow battery, which shows stable operation for about 120 h (i.e., 2100 charge-discharge cycles at 100 mA cm^-2) in a laboratory-scale cell.

A series of luminescent cocrystals with fluoranthene (C16H10) as the fluorophore and benzene-1,2,4,5-tetracarbonitrile (TCNB, C10H2N4), 2,3,5,6-tetrafluorobenzene-1,4-dicarbonitrile (TFP, C8F4N2) and 1,2,3,4,5,6,7,8-octafluoronaphthalene (OFN, C10F8) as the coformers was designed and synthesized. Structure anal. revealed that these layered structures were due to charge transfer, π-π interactions and hydrogen bonding. D. functional theory (DFT) calculations show that fluoranthene-TCNB and fluoranthene-TFP have charge-transfer properties, while fluoranthene-OFN does not, indicating that fluoranthene-OFN has arene-perfluoroarene (AP) interactions, which was also demonstrated by spectroscopic anal., which shows that the photophys. properties of luminescent materials can be tuned by forming cocrystals. These results all prove that utilizing supramol. cocrystals to develop new fluorescent materials is an effective strategy, which has much potential in optoelectronic applications.

Xia, Yu;Wang, Yan;Cao, Hongyan;Lin, Shuhao;Xia, Yongsheng;Hou, Xiaoxuan;Wu, Yulin;Yu, Ying;Huang, Kang;Xing, Weihong;Xu, Zhi research published 《 Rigidly and intrinsically microporous polymer reinforced sulfonated polyether ether ketone membrane for vanadium flow battery》, the research content is summarized as follows. Ion exchange membranes (IEMs) blending porous materials have shown great potential for the large-scale energy storage technologies, such as flow battery. However, it remains challenging to overcome the compatibility issue between polymer and porous fillers. In this work, the polymer of intrinsic microporosity (PIM) was successfully introduced into sulfonated polyether ether ketone with high degree of sulfonation (HDS-SPEEK) membrane. PIM exhibited desirable compatibility with HDS-SPEEK due to the natural polymer property. Meanwhile, the rigid skeleton structure of PIM effectively solved the problems of HDS-SPEEK involving poor mech. property and low vanadium resistance. With increasing the doping of carboxyl grafting modified PIM, the tensile strength increased from 15.22 to 29.94 MPa and the vanadium permeability declined from 4.4 x 10^-6 to 1.6 x 10^-7 cm² min^-1. As a result, the vanadium flow battery equipped with the optimized blend membrane showed significantly enhanced coulombic efficiency from 55% to 99% at the c.d. of 20 mA cm^-2, and had good long-term stability. This work presents a new route to prepare high-performance IEMs based on porous PIM materials for flow battery.

Xiong, Shaohui;Pan, Chunyue;Dai, Guoliu;Liu, Cheng;Tan, Zhijian;Chen, Chuang;Yang, Song;Ruan, Xuehua;Tang, Juntao;Yu, Guipeng research published 《 Interfacial co-weaving of AO-PIM-1 and ZIF-8 in composite membranes for enhanced H₂ purification》, the research content is summarized as follows. Porous asym. composite membranes (ACMs) have attracted intensive attentions in energy-efficient gas separations However, fabricating ACMs with defect-free interface and enhanced selectivity without sacrificing permeability remains great challenge. Herein, a major step towards this goal is proposed by employing an efficient co-weaving strategy to regulate interfacial microstructure of ACMs with bilayer geometry on porous substrates. The double layers are constructed by in-situ growing zeolitic imidazolate frameworks-8 (ZIF-8) on the surface of amidoxime-functionalized polymer of intrinsic microporosity-1 (AO-PIM-1) layer (denoted as AO-PIM-1@ZIF-8). The pre-designed amidoxime groups on the AO-PIM-1 backbone provide abundant coordinate sites for Zn (II) ions, offering advantages for building a continuous membrane. Consequently, the obtained AO-PIM-1@ZIF-8 membrane demonstrates remarkable performance in H₂/CO₂ separations, with the H₂/CO₂ selectivity of 11.97 and the H₂ permeability of up to 5688 Barrer at 298 K and 1 bar. Both the H₂ permeability and H₂/CO₂ selectivity exceed most of reported ACMs. This is contributed either by position-space renormalization for AO-PIM-1 chains or pore space partition in ZIF-8 at the interface. The study reports herein offer an alternative route to develop high-performance composite membranes for improved gas separations

Xu, Shuainan;Jin, Yehao;Li, Rui;Shan, Meixia;Zhang, Yatao research published 《 Amidoxime modified polymers of intrinsic microporosity/alginate composite hydrogel beads for efficient adsorption of cationic dyes from aqueous solution》, the research content is summarized as follows. Polymers of intrinsic microporosity (PIM-1) has demonstrated great potential in adsorption and separation fields. In this study, PIM-1 was structured into an applicable and efficient adsorbent using a facile way. PIM-1 was first modified by amidoxime, and then the amidoxime modified PIM-1 (AOPIM-1) was mingled into alginate (Alg) hydrogel to obtain composite hydrogel beads. The AOPIM-1/Alg composite beads were further employed for removal of malachite green (MG) from aqueous solution and the effects of doped ratio, adsorbent dosage, contact time, and initial dye concentration on the MG adsorption performance were systematically investigated. The MG adsorption capacity of pure Alg beads was substantially enhanced after incorporating AOPIM-1. Furthermore, isothermal, kinetic and thermodn. studies were performed to explore the fundamental adsorption behavior. Both Freundlich isotherm and Langmuir isotherm models can fit the adsorption isotherm data well, and the adsorption kinetics is well described by Pseudo-second-order. The adsorption process is feasible, spontaneous and endothermic. In addition, mixed dyes adsorption measurements indicate that AOPIM-1/Alg beads are highly selective to adsorb cationic dyes from anionic/cationic mixed dyes solution The regeneration test shows that above 90% of the adsorption capacity of the composite beads can be maintained after 10 cycles of MG adsorption/desorption. These findings point that AOPIM-1/Alg composite hydrogel beads are an efficient, up-and-coming and recyclable adsorbent for cationic dyes adsorption from aqueous solution

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).
