Wu, Yanan;Gui, Huiqiang;Ma, Liangwei;Zou, Lei;Ma, Xiang research published 《 Red-light emissive phosphorescent polymers based on X-shaped single benzene》, the research content is summarized as follows. 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. In this study, a series of X-shaped phosphors derived from tetrafluoroterephthalonitrile were synthesized and copolymerized with acrylamide to obtain RTP materials. 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.

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.

Knoevenagel condensation reaction is an important reaction for the manufacture of α,β-unsaturated carbonyl compounds Traditional base catalysts suffer from the disadvantage in catalyst-product separation Herein, potassium-doped carbon nitride materials supported on SBA-15 (CN/SBA15-KCl) have been prepared through a one-pot calcination method. The characterization results of N2 adsorption-desorption, small-angle XRD, TEM, and SEM revealed that the ordered mesostructures of SBA-15 had been preserved after the loading of carbon nitride and KCl, and nitrogen and potassium species were dispersed on the surface of SBA-15 support. As solid bases, the CN/SBA15-KCl materials demonstrated high and steady catalytic performances in Knoevenagel condensation. Under 50°C of reaction temperature, the optimized conversion of benzaldehyde was up to 74% at 4 h of reaction time, much higher than other carbon-nitride-based materials. The incorporation of potassium has been proved to enhance the basic strength of CN/SBA15, and therefore improved the catalytic activity.

Williams, Matthew B.;Boyer, Alistair research published 《 Modular Synthesis of Highly Substituted 3-Azapyrroles by Rh(II) Catalyzed N-H Bond Insertion and Cyclodehydration》, the research content is summarized as follows. A modular synthesis of highly substituted 3-azapyrroles, e.g., I has been developed using a three-step sequence comprising: copper catalyzed alkyne-azide cycloaddition (CuAAC), N-H bond insertion and cyclodehydration. The compound 1-sulfonyl-1,2,3-triazoles (1-STs), e.g., 4-tolyl-1-tosyl-triazole can be accessed from common alkynes, e.g., 4-ethynyltoluene and sulfonyl azides, e.g., 4-toluenesulfonyl azide building blocks by CuAAC using copper(I) thiophene-2-carboxylate. Rhodium(II) acetate promoted 1-ST denitrogenation results in highly electrophilic rhodium azavinyl carbenes that, here, underwent insertion into the N-H bond of secondary α-aminoketones, e.g., 1-(4-tolyl)-2-(4-tolylamino)ethan-1-one to form 1,2-aminoalkenes, e.g., 1-[(2-oxo-2-(4-tolyl)ethyl)(4-tolyl)amino]-1-(4-tolyl)-2-(tosylamino)ethene. These products were cyclized and dehydrated using BF3OEt2 into highly substituted 3-azapyrroles, e.g., I. The three steps: CuAAC, N-H bond insertion and cyclodehydration could be telescoped into a one-pot process. The method proved to be highly efficient and tolerated a wide range of substituents.

The key challenge of developing reaction-based turn-on probes is to establish latent electrophilic fluorophores exhibiting high reactivity only upon binding to a specific protein(s). Herein, we identified such a fluorophore, 6-arylthioether-substituted 3-cyano-1-oxo-1H-phenalene-2-carboxylate, which chemoselectively labels binding site Cys or Lys residues. Based on this fluorophore, we developed the first reaction-based turn-on pyruvate kinase M2 isoform (PKM2) fluorescent probe AT-OPC1, which selectively labels PKM2 with the binding site Lys305. The latent electrophilic reactivity of the fluorophore endows the probe with precise detection of the expression of PKM2 in situ by means of both in-gel fluorescence imaging at the proteome level and real-time no-wash cell imaging approaches, which has the potential to be applied in cancer diagnoses.

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.
