Han, Weiyao;Zhang, Caili;Zhao, Min;Yang, Fan;Yang, Yang;Weng, Yunxuan research published 《 Post-modification of PIM-1 and simultaneously in situ synthesis of porous polymer networks into PIM-1 matrix to enhance CO₂ separation performance》, the research content is summarized as follows. Post-modification of the chem. structures can be used to tailor the properties of polymers of intrinsic microporosity (PIM-1), which shows promise for application of PIM-1 gas separation membrane. Methane sulfonic acid (MSA) is capable of hydrolyzing and crosslinking nitrile groups of PIM-1 to form carboxylic acid-contained and triazine groups crosslinked PIM-1 (cPIM-1), and simultaneously catalyze in situ synthesis of porous polymer networks (PPNs) in PIM-1 matrix. These reactions were carried out at the same time by a one-step method. Characterization of hydrolysis and crosslinking process of nitrile groups in PIM-1 was performed by ATR, XPS, solubility, and ¹H NMR anal. MSA catalyzed synthetic approach of PPNs includes the trimerization of three acetyl groups and involves a coupled process of polymerization and membrane architecture formation. Finally, the process of crosslinking and hydrolysis can provide enhanced gas pair selectivity of PIM-1 membrane (cPIM-1) while the gas permeability of the membranes (cPIM-1/PPNs) can be increased by the incorporation of PPNs microstructure networks. As a result, the optimal cPIM-1/PPNs showed Roberson’s 2008 upper bound separation performance for CO₂/CH₄ and CO₂/N₂. The cPIM-1/PPN2-3% membrane demonstrated the best CO₂ comprehensive separation performance with the permeability of almost 11511 Barrer, with ideal selectivity of 24.3 and 22.2 for CO₂/N₂ and CO₂/CH₄ resp. Furthermore, the cPIM-1/PPNs membranes show excellent anti-aging properties. This indicates that MSA-catalyzed hydrolysis, crosslinking and in situ synthesis PPNs can effectively adjust the topol. structure of PIM-1 membrane for CO₂ separation

Han, Jiuli;Jiang, Haiyan;Zeng, Shaojuan;Bai, Yinge;Zhang, Xiangping;Bai, Lu research published 《 CO₂ separation performance for PIM based mixed matrix membranes embedded by superbase ionic liquids》, the research content is summarized as follows. Mixed matrix membranes (MMMs) have drawn much interest in CO₂ separation due to their excellent separation performance, mech. property, and desirable processability. However, obtaining highly compatible MMMs is a great challenge and is vital to avoid the loss of the separation selectivity of the MMMs. In this work, superbase ionic liquid (1,8-diazabicyclo[5,4,0]undec-7-ene imidazole ([HDBU][Im])) was used as a wetting agent to increase the interfacial compatibility between ZIF-67 and PIM-1, hence improving the membrane gas separation [HDBU][Im] embeding into the MMMs could efficiently enhance the compatibility and diminish the interfacial voids. Furthermore, incorporating 5 wt% [HDBU][Im]@ZIF-67 nanocomposite into the PIM-1 matrix improves the gas permeability and CO₂ selectivity. The separation performances under the different temperatures were also conducted and showed that reducing temperature slightly decreases the gas permeability but significantly increases the CO₂/CH₄ selectivity via enhancing the CO₂ solubility The permeation active energies, diffusivities and solubilities were obtained to explain the gas permeate mechanism.

Dithiine linkage formation via a dynamic and self-correcting nucleophilic aromatic substitution reaction enables the de novo synthesis of a porous thianthrene-based two-dimensional covalent organic framework (COF). For the first time, this organo-sulfur moiety is integrated as a structural building block into a crystalline layered COF. The structure of the new material deviates from the typical planar interlayer π-stacking of the COF to form undulated layers caused by bending along the C-S-C bridge, without loss of aromaticity and crystallinity of the overall COF structure. Comprehensive exptl. and theor. investigations of the COF and a model compound, featuring the thianthrene moiety, suggest partial delocalization of sulfur lone pair electrons over the aromatic backbone of the COF decreasing the band gap and promoting redox activity. Postsynthetic sulfurization allows for direct covalent attachment of polysulfides to the carbon backbone of the framework to afford a mol.-designed cathode material for lithium-sulfur (Li-S) batteries with a minimized polysulfide shuttle. The fabricated coin cell delivers nearly 77% of the initial capacity even after 500 charge-discharge cycles at 500 mA/g c.d. This novel sulfur linkage in COF chem. is an ideal structural motif for designing model materials for studying advanced electrode materials for Li-S batteries on a mol. level.

Hadimane, Sowmyashree;Aralekallu, Shambhulinga;CP, Keshavananda Prabhu;Hojamberdiev, Mirabbos;Sannegowda, Lokesh Koodlur research published 《 Bioinspired Precious-Metal-Free N4 Macrocycle as an Electrocatalyst for the Hydrogen Evolution Reaction》, the research content is summarized as follows. The design and development of strategies and catalysts are essential for sustainable energy production, particularly for the hydrogen evolution reaction (HER). Precious Pt/C catalyst is known to demonstrate high efficiency in the electrochem. HER and suffers from commercialization issues. Therefore, precious-metal-free and organic-based catalysts are of importance for a future perspective. In this work, cobalt tetra[4-[2-(1H-benzimidazol-2-yl)phenoxy]]phthalocyanine (CoTBImPc) is synthesized for the first time and characterized by physicochem. and electrochem. techniques. ¹H NMR and mass spectral data reveal the successful formation of the ligand and complex, whereas the thermogravimetry (TG) study confirms the thermal stability of the complex up to 400 °C. The electroactivity of CoTBImPc is compared with the hybrid composite of a carbon nanotube (CNT-CoTBImPc) and benchmark Pt/C catalyst for the HER. Linear sweep voltammetry (LSV) shows that an onset potential for the HER for CoTBImPc-CNT/GCE is shifted to a higher potential than that of CoTBImPc/GCE, suggesting that the HER is more feasible at the surface of CoTBImPc-CNT. Higher activity for CoTBImPc-CNT/GCE in comparison with that of CoTBImPc/GCE in 0.5 M H₂SO₄ (pH = 0.3) may be ascribed to the enhanced conductivity, a greater number of active sites, and a larger surface area. The hybrid composite yields a c.d. of -10 mA·cm^-2 and demonstrates HER activity at a lower overpotential (63 mV). The benchmark Pt/C catalyst and the as-synthesized pristine phthalocyanine mol. exhibit the HER at overpotentials of 3 and 160 mV, resp., at a c.d. of -10 mA·cm^-2. A lower Tafel slope value of 43.2 mV·dec^-1 and a higher double-layer capacitance value of 44 mF·cm^-2 confirm that the hybrid composite is one of the superior catalyst candidates for the HER compared to the bare glassy carbon electrode (GCE) and pristine metal phthalocyanine. Further, CoTBImPc-CNT/GCE also exhibits an excellent stability during the HER.

Guzel, Emre;Atmaca, Goknur Yasa;Kuznetsov, Aleksey E.;Turkkol, Aysegul;Bilgin, Mehmet Dincer;Erdogmus, Ali research published 《 Ultrasound versus Light: Exploring Photophysicochemical and Sonochemical Properties of Phthalocyanine-Based Therapeutics, Theoretical Study, and In Vitro Evaluations》, the research content is summarized as follows. Photodynamic therapy (PDT) applications carried out with the assistance of ultrasound have attracted significant attention in recent years. The use of phthalocyanines, which are an important component as photosensitizers in PDT, is becoming more important day by day. In therapeutic applications, phthalocyanines can promote the production of reactive oxygen species. Motivated by this fact, the syntheses of metal-free (2), gallium (3), and indium (4) phthalocyanines have been achieved by substituting 4-(cinnamyloxy)phthalonitrile for the first time to evaluate their therapeutic applications. Addnl., photophysicochem., sonophotochem., and in vitro evaluations of phthalocyanines have been reported. To the best of our knowledge, this is the first study of the use of phthalocyanines with different metal ions as potential photosensitizers for sonophotodynamic therapy (SPDT) applications in gastric cancer cell lines. The results show that the quantum yield of the generation of singlet oxygen increased in sonophotochem. studies (Φ_Δ = 0.55 (2), 0.85 (3), 0.96 (4)), compared to photochem. studies (Φ_Δ = 0.22 (2), 0.61 (3), 0.78 (4)). The d. functional theory (DFT) results are in good agreement with the exptl. results and suggest increased reactivity of phthalocyanines 3 and 4 in various redox processes, thus implying their applicability and usefulness as potential therapeutic agents. These phthalocyanines are effective sensitizers for PDT, sonodynamic therapy (SDT), and SPDT against MKN-28 gastric cancer cell line in vitro. All three treatments decreased cell viability and induced apoptosis in the gastric cancer cell line. However, indium phthalocyanine (4)-mediated SPDT was a more effective treatment modality compared to indium phthalocyanine (4)-mediated PDT and SDT. Also, indium phthalocyanine (4) was found to be a more effective sensitizer to activate apoptosis compared to the other phthalocyanines. To sum up, phthalocyanine-mediated SPDT enhances the cytotoxic effect on gastric cancer cells more than the effect of SDT or PDT alone.

Guo, Yu;Zhang, Lingling;You, Hongjun;Fang, Jixiang research published 《 A solution-based SERS sensing protocol via the ultra-rapid and highly efficient molecule enrichment strategy》, the research content is summarized as follows. The solution-based SERS detection has been considered as one of the most mature com. SERS detection protocols owing to its features of high sensitivity and timeliness. However, poor mol. generality is a challenge for weakly-adsorbed species, such as anionic mols. and complicated organic compositions, on the surfaces of the plasmonic nanostructures. Many mols. in solution especially the weakly-adsorbed organic pollutants cannot be effectively adsorbed onto the surface of metal nanoparticles quickly due to the low affinities towards the metal, hence showing the weak Raman activity. Herein, we report a solution-based SERS sensing protocol via the highly efficient mol. enrichment strategy to achieve highly sensitive detection in solution With the help of pH adjustment in solution, the porous β-cyclodextrin polymer/magnetic nanoparticles (PCDPMNs) can availably capture various types of mols., including cationic dyes (e.g., methylene blue and crystal violet), anionic pigment (e.g., sunset yellow), and neutral organic pollutants (e.g., carbendazim and bisphenol A). Based on the mol. enrichment strategy, the enrichment factors of various mols. are up to 10²-10³, thus their Raman signals are enhanced by 2-3 orders of magnitude. The mol. enrichment strategy provides a new way for the practical SERS detection to improve the ultra-trace detection in solution
