Yildiz, Burak;Arslan, Baris Seckin;Guzel, Emre;Nebioglu, Mehmet;Menges, Nurettin;Sisman, Ilkay;Kasim Sener, M. research published 《 Non-aggregating zinc phthalocyanine sensitizer with bulky diphenylphenoxy donor groups and pyrazole-3-carboxylic acid anchoring group for coadsorbent-free dye-sensitized solar cells》, the research content is summarized as follows. A novel unsym. zinc phthalocyanine complex (PCA-ZnPc-3) containing six 2,6-diphenylphenoxy donor groups and pyrazole-3-carboxylic acid anchoring group has been synthesized and used as a sensitizer for dye-sensitized solar cells (DSSCs). The optical, electrochem. and photovoltaic characteristics were evaluated and compared with the dyes containing the same anchoring group and tert-Bu (PCA-ZnPc-1) or hexylsulfanyl (PCA-ZnPc-2) donor groups, developed by our group. The DSSC with PCA-ZnPc-3 exhibited a higher power conversion efficiency (PCE) of 2.04% as compared to that of PCA-ZnPc-1 (PCE = 1.74%) and PCA-ZnPc-2 (PCE = 1.89%). This enhancement in efficiency may be ascribed to the less dye aggregation and appropriate dye coverage. These results suggest that the incorporation of 2,6-diphenylphenoxy into pyrazole-3-carboxylic acid-based zinc phthalocyanine sensitizers can improve photovoltaic performance of DSSCs.

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.

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.

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.

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.
