Newly developed tetra- and octasubstituted methimazole-phthalocyanine conjugates as potential photosensitizers have been obtained. Synthesized intermediates and final products were characterized by the MALD-TOF technique and various NMR techniques, including 2D methods. Single-crystal X-ray diffraction was used to determine the crystal structures of dinitriles. The studied phthalocyanines revealed two typical absorption bands-the Soret band and the Q band. The most intense fluorescence was observed for octasubstituted magnesium(II) phthalocyanine in DMF (Φ_FL = 0.022). The best singlet oxygen generators were octasubstituted magnesium(II) and zinc(II) phthalocyanines (Φ_Δ 0.56 and 0.81, resp.). The studied compounds presented quantum yields of photodegradation at the level between 10^-5 and 10^-6. Due to their low solubility in a water environment, the liposomal formulations were prepared Within the studied group, octasubstituted zinc(II) phthalocyanine at the concentration of 100 μM activated with red light showed the highest antibacterial activity against S. aureus equal to a 5.68 log reduction of bacterial growth.

Wang, Ziqian;Zhang, Xiaodong;Zhang, Hong;Tang, Yao;Pan, Hao;Wang, Hang;Ji, Tong;Guo, Yafei;Gao, Qishuang;Song, Ting;Zhang, Zhichao research published 《 Discovery of a fluorogenic probe for in situ pyruvate kinase M2 isoform (PKM2) labeling through chemoselective S_NAr with a binding site lysine residue》, the research content is summarized as follows. 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.

Wang, Yan;Chen, Yaqi;Bian, He;Sun, Yawei;Zhu, Lijun;Xia, Daohong research published 《 Highly selective and sensitive chiral recognition to deoxynucleosides by calixarene oligomers modified silver nanoparticles》, the research content is summarized as follows. 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.

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.

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.

Aromatic triangular tri-palladium cations, abbreviated as [Pd₃]⁺, have shown interesting photoelec. properties, Lewis basic character, and excellent activities in catalytic hydrogenation. Herein, authors report the highly efficient and C-I selective Sonogashira and Heck coupling reactions catalyzed by these tri-palladium complexes. Benefiting from the moderate C-I bond association energy, these tri-palladiums presented exclusive reactivities to aryl iodides over the brominated aromatics in coupling reactions. In the Sonogashira pathway, good to excellent isolated yields (71-95%) were achieved. Gram-scale reaction reached 93% of yield with palladium loading as few as 0.06 mol %. Authors also explored the electronic and steric effects for Ph alkynes and aryl iodides including heteroaromatics like thiophene, pyridine, pyrazole, and pyrazine. Similarly, yields of 71-96% were obtained for palladium loading of 1.5 mol% through catalyzed Heck coupling of aryl iodides and alkenes. The HRMS monitoring revealed that [Pd₃]⁺ maintained as whole entity during the catalytic process due to its robusness.
