Wu, Pengfei;Zhou, Long;Xia, Shuwei;Yu, Liangmin research published 《 Synthesis of luminescent cocrystals based on fluoranthene and the analysis of weak interactions and photophysical properties》, the research content is summarized as follows. 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).

Polymers with intrinsic microporosity (PIMs) have recently received increasing interest in the fields of gas separation, sensors, catalysts, and so on, due to their high microporosity and good solution processability. However, PIMs with chiral backbones are quite limited, which undoubtedly hinders their applications in many areas such as chiral separation and optoelectronics. Herein, the catalytic enantioselective synthesis of a novel cyclohexyl-fused spirobiindane-based chiral PIM is described. This novel polymer exhibits high intrinsic microporosity (S_BET = 796 m² g^-1), solubility, and good film formability. Its macroscopic chirality of the twist-bend structure was confirmed by CD. More interestingly, circular polarized luminescence (CPL) was observed for the first time in PIMs; also, to our best knowledge, this is the first nonconjugated porous CPL polymer, opening the door to explore new research fields of PIM materials, as well as providing new guidance for CPL polymer design.

The development of aggregation-induced emission luminogens (AIEgens) has attracted increasing attention due to their potential applications in various areas in recent years. In this study, a facile conversion from aggregation-caused quenching (ACQ) to aggregation-induced emission (AIE) was achieved by an efficient regioisomerization strategy based on the rofecoxib scaffold. Two compounds, named PYR2 and PYR4, were identified as regioisomers of rofecoxib derivatives to show dramatically different fluorescent properties. Compound PYR2 with an ortho-substituted piperidine group showed typical AIE activity while compound PYR4 with a para-piperidine group exhibited typical ACQ behavior. Notably, compound PYR2 showed polymorphism with two forms of crystals. It was also endowed with reversible mechanochromic luminescence and acidochromic properties. The different fluorescent properties were elucidated by UV/Vis absorption spectroscopy, powder X-ray diffraction, differential scanning calorimetry, and thermogravimetric analyzes. Its application as a security ink and in lipid droplets imaging have been demonstrated.

Efficient enantiomeric sensing to deoxynucleosides by a simple method is of great importantance and remains a challenge in biochem. field. In this paper, three chiral calixarene oligomers (CA[n]P, n=4, 6, 8) were synthesized and characterized by Fourier Transform IR Spectroscopy, UV-vis spectrophotometry, CD spectroscopy , X-ray Powder Diffraction, XPS, Matrix Assisted Laser Desorption Ionization Time of Flight Mass Spectrometry, ¹⁹F NMR and SEM. After that, the chiral calixarene oligomers capped silver nanoparticles (CA[n]P-Ag NPs, n=4, 6, 8) were prepared and characterized by FT-IR, UV-vis spectrophotometry, CD and dynamic light scattering. By using the as prepared CA[n]P-Ag NPs (n=4, 6, 8), highly selective and sensitive chiral recognition to deoxynucleosides was realized and demonstrated by UV-vis and CD. The color of the CAP-Ag NPs changes from yellow to red in the presence of β-L-2′-deoxycytidine (L-dC) or β-L-2′-deoxythymidine (L-dT) at a certain time, but not of their corresponding enantiomer β-D-2′-deoxycytidine (D-dC) or β-L-2′-deoxythymidine (D-dT). Moreover, the chiral recognition ability of CA[n]P-Ag NPs (n=4, 6, 8) toward L-deoxynucleosides was found to be in the order of CA[8]P-Ag NPs>CA[6]P-Ag NPs>CA[4]P-Ag NPs. This convenient method shows forceful prospect in developing biochem. sensors and has the potential application in enantiomeric recognition and separation of deoxynucleosides.
