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.

Recently, the single benzene mol. has attracted widespread attention in room temperature phosphorescence (RTP) materials for its simple structure. However, it is difficult to achieve the long wavelength emission and there are few feasible, universal strategies to construct phosphors with long wavelength emission.

Polymers containing selenium (Se) atoms exhibited long wavelength RTP emission around 600 nm and over 200 nm Stokes shift. PN1, the fluorescence and phosphorescence dual emission material, exhibited red phosphorescence emission at 605 nm. Theor. calculation was performed to explain the underlying reasons for the produce of phosphorescence.

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.

Seeking high-performance coating with long service life to protect metallic substrates under complex corrosion environment has attracted abundant attention in modern industry. In this work, poly(arylene ether nitrile) (PEN) was applied as protective coating on metallic substrates for the first time, and the cyano-functionalized multiwalled carbon nanotubes (MWCNTs-CN) was introduced to further enhance the corrosion resistance and mech. performance of the PEN coating. Electrochem. results demonstrated that the MWCNTs-CN incorporated composite coating possessed outstanding corrosion resistance that the |Z|0.01Hz remained 196.9 MΩ cm2 after 100 days immersion process in 3.5 wt% NaCl solution, which was 2 orders of magnitude higher than the pure PEN coating. Besides, an evident improvement was investigated from the tensile strength of MWCNTs-CN/PEN coatings, which showed an increment about 20.1% of tensile strength was gained when 1 wt% of MWCNTs-CN was introduced. Benefiting from these advantages, this work is expected to provide a novel insight in high-performance protective coating.

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
