Huang, Menghui;Wang, Zhenggong;Lu, Kuan;Fang, Wangxi;Bi, Xiangyu;Zhang, Yatao;Jin, Jian research published 《 In-situ generation of polymer molecular sieves in polymer membranes for highly selective gas separation》, the research content is summarized as follows. Mol. sieve materials (MSMs) are regarded as ideal fillers for the fabrication of mixed matrix membranes (MMMs). However, the preparation of MSMs-based MMMs usually involves phys. mixing of insoluble filler and polymer matrix, which inevitably leads to filler agglomeration and two-phase incompatibility especially for high filler loading. Herein, we report a new strategy to construct MMMs through generating polymer mol. sieve (PMS) fillers in-situ in a thermally stable polymer matrix by post heating treatment. The in-situ generated PMS-based MMMs (i-PMS MMMs) possess greatly improved interfacial compatibility between matrix and filler and the effective loading content of PMS filler can reach as high as 70 wt%. The mol. sieving property of PMS endows the i-PMS MMMs with high gas selectivity of 183.0 for H₂/CH₄ and 128.9 for H₂/N₂, approaching or exceeding the state-of-the-art 2015 upper bound.

Huang, Qiang;Wang, Wei-Na;Zhu, Shou-Fei research published 《 Iron-Catalyzed Alkylzincation of Terminal Alkynes》, the research content is summarized as follows. Although carbozincation of terminal alkynes is a promising method for the synthesis of alkenylzinc reagents, many challenges, especially the chemo-, regio-, and stereoselectivity, remain to be addressed. The authors herein report an operationally simple, mild method for Fe-catalyzed alkylzincation of terminal alkynes to produce a diverse array of alkenylzinc compounds in high yields with high anti-Markovnikov selectivity and high cis stereoselectivity. Using this method, the authors realized a cis alkylzincation of terminal alkynes, and the method has a wide substrate scope (being suitable for aryl, alkenyl, alkyl, and heteroatom-substituted acetylenes) and good functional group tolerance. Because the C(sp²)-Zn bonds of the products can be readily transformed, the method provides a competitive alternative to traditional methods for the selective synthesis of trisubstituted olefins. The Fe catalyst developed in this study exhibited irreplaceable reactivity in alkyne alkylzincation.

The palladium-catalyzed tail-to-tail reductive dimerization of terminal alkynes was described for the first time. Aromatic terminal alkynes bearing diverse and sensitive functional groups as well as aliphatic terminal alkynes are efficiently transformed to 2,3-dibranched butadienes H₂C(R)CC(R)CH₂ [R = Ph, 2-naphthyl, 2-thienyl, etc.]. The key to achieve a selective tail-to-tail reductive dimerization reaction is to control appropriately the acidity of the reaction solution, which is accomplished by a combined use of pivalic acid and para-toluenesulfonic acid. The tail-to-tail reductive dimerization reaction is proposed to proceed via a cationic alkenyl palladium intermediate under acidic conditions.

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

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.
