Kantekin, Halit;Yalazan, Halise;Barut, Burak;Gungor, Omer;Unluer, Dilek;Demirbas, Umit;Ozel, Arzu;Durmus, Mahmut research published ã€?Dual-purpose both peripheral and non-peripheral triazole substituted ZnII, MgII and PbII phthalocyanines: Synthesis, characterization, photophysicochemical and acetylcholinesterase inhibitory propertiesã€? the research content is summarized as follows. Both peripheral and non-peripheral 4-(3,4-dimethoxyphenethyl)-5-ethyl-2H-1,2,4-triazol-3(4H)-one substituted zinc(II), magnesium(II) and lead(II) phthalocyanines were synthesized in this paper. Techniques used to illuminate the structure of these phthalocyanines included FT-IR, MALDI TOF, UV-Vis, NMR spectroscopy. The ZnIIPcs (p/np–ZnPcs), MgIIPcs (p/np–MgPcs) and PbIIPcs (p/np–PbPcs) exhibited outstanding solubility in common organic solvents such as 1,4-Dioxane, acetonitrile, chloroform, dichloromethane, DMF, dimethylsulfoxide, Et acetate and THF. The photophysicochem. properties of ZnIIPcs, MgIIPcs and PbIIPcs were researched in DMSO. The positions of the substituents (peripheral or non-peripheral) and the effects of the central metal ions (Zn2+, Mg2+, Pb2+) on the photophysicochem. properties were reported by comparison. The singlet oxygen quantum yield values of ZnIIPcs, MgIIPcs and PbIIPcs ranged from 0.11 to 0.78 in DMSO. The newly synthesized peripherally tetra substituted zinc(II) phthalocyanine (p–ZnPc) exhibited high singlet oxygen generation in DMSO compared to unsubstituted zinc(II) phthalocyanine used as standard These results indicate that the (p–ZnPc) can be a candidate as photosensitizer for PDT. Besides, the inhibitory properties of the compounds were determined using the spectrophotometric method on AChE and α-glucosidase. IC50 values showed that np-MgPc has highest inhibitory actions among the tested compounds on AChE and α-glucosidase.

Jung, Dahee;Su, Shengyi;Syed, Zoha H.;Atilgan, Ahmet;Wang, Xingjie;Sha, Fanrui;Lei, Yifan;Gianneschi, Nathan C.;Islamoglu, Timur;Farha, Omar K. research published �A Catalytically Accessible Polyoxometalate in a Porous Fiber for Degradation of a Mustard Gas Simulant� the research content is summarized as follows. Polyoxometalates (POMs) are versatile materials for chem. catalysis due to their tunable acidity and rich redox properties. While POMs have attracted significant attention in homogeneous catalysis, challenges regarding aggregation and instability in solvents often prevent the wide implementation of POMs as heterogeneous catalysts. Therefore, the successful incorporation of a POM into a solid support, such as a polymer, is desirable for practical applications where unique functionalities of the POM combine with the advantages of the polymer. In this work, we showcase how polymers of intrinsic microporosity (PIMs) can serve as matrixes for anchoring a pure inorganic Keggin-type POM (H3PW12O40) to fabricate PIM-based composite materials. Specifically, we found that PIMs installed with amidoxime functionalities could successfully attach POMs (PW12@PIM-1-AO) without self-segregation. Furthermore, we fabricated porous fibrous mats via electrospinning of the PIM-POM composites. Comprehensive characterization confirmed the integrity of the POM in the composite material. Following this, we demonstrated that the incorporated POMs in the composite fibers maintained their innate catalytic activity for the oxidative degradation of 2-chloroethyl Et sulfide, a sulfur mustard simulant, in the presence of hydrogen peroxide as the oxidant. Ultimately, our work highlights that PIM-based hybrid materials provide a potential route for implementing these reactive fiber mats into protective equipment.

Jin, Yehao;Song, Qiangqiang;Xie, Na;Zheng, Weigang;Wang, Jing;Zhu, Junyong;Zhang, Yatao research published �Amidoxime-functionalized polymer of intrinsic microporosity (AOPIM-1)-based thin film composite membranes with ultrahigh permeance for organic solvent nanofiltration� the research content is summarized as follows. Advanced organic solvent nanofiltration (OSN) membranes with high permeance and stability are highly needed in petrochem. and pharmaceutical industries. Recently, polymers of intrinsic microporosity (PIMs) have attracted significant attention for the development of advanced membranes, because of their high porosity and solution processability. In this study, a thin film composite membrane based on an amidoxime-functionalized PIM (AOPIM-1) was prepared by spin coating followed by solvent activation. The activation approach could dramatically improve the solvent permeance of the membrane without compromising its rejection performance. The changes in porosity of the AOPIM-1 layer before and after activation were confirmed by positron annihilation Doppler spectroscopy. The optimum membrane exhibited an impressively high ethanol permeance of 15.5 L m-2 h-1 bar-1, nearly one orders of magnitude higher than that of Starmem 240 (a com. polyimide-based OSN membrane) with a comparable rejection of Rose Bengal (MW 1017 Da). In addition, the present membrane exhibited outstanding stability in polar solvents and a remarkably high rejection of active pharmaceutical ingredients (vitamin B12) from ethanol. This work could provide a new avenue for developing highly permeable OSN membranes and is expected to stimulate the use of PIM membranes in OSN applications.

It can also be prepared using nitro phenol and sodium hydroxide. 4-Nitrophthalonitrile has been shown to have high photochemical activity in the presence of light. The frequency shift of its infrared spectrum is indicative of a nucleophilic addition reaction mechanism. 4-Nitrophthalonitrile has been used as an intermediate for producing other chemicals, such as herbicides and pharmaceuticals., 31643-49-9.

Industrially, the main methods for producing nitriles are ammoxidation and hydrocyanation. 31643-49-9, formula is C8H3N3O2, Name is 4-Nitrophthalonitrile. Both routes are green in the sense that they do not generate stoichiometric amounts of salts. Recommanded Product: 4-Nitrophthalonitrile.

Jiang, Hongyu;Jiang, Hanzhou;Chen, Guofei;Fang, Xingzhong research published ã€?Synthesis and comparative study on polyetherimides from isomeric 4,4′-isopropylidenediphenoxy bis(phthalic anhydride)sã€? the research content is summarized as follows. Two isomers of com. 4,4′-(4,4′-isopropylidenediphenoxy) bis(phthalic anhydride) (4,4′-BPADA), i.e., 3,4′-(4,4′-isopropylidenediphenoxy) bis(phthalic anhydride) (3,4′-BPADA) and 3,3′-(4,4′-isopropylidenediphenoxy) bis(phthalic anhydride) (3,3′-BPADA), were synthesized through aromatic nucleophilic substitution from nitrophthalonitrile and bisphenol A. 3,4′-BPADA was first synthesized from two intermediates, i.e., 3-(4-[4-hydroxyphenylisopropylidene] phenoxy) phthalonitrile (3-BPADN) and 3,4′-(4,4′-isopropylidenediphenoxy) bis(phthalonitrile) (3,4′-BPATN). The corresponding three series of polyetherimides (PEIs) were prepared with two representative aromatic diamines (4,4′-oxydianiline and m-phenylenediamine (m-PDA)) via two-step procedure and chem. imidization. Isomeric polyimides showed Tgs from 206 to 256°C in nitrogen and Td5%s from 488 to 511°C in argon, good mech. properties (tensile moduli of 2.3-3.3 GPa, tensile strengths of 70-96 MPa, and elongations at break of 3.2%-5.1%), and good solubility With the introduction of 3-substituted phthalimide unit, PEIs displayed higher Tg values, lower strengths and elongations, better solubility and larger d-spacings. The rheol. properties of thermoplastic polyimide resins based on the BPADA isomers were investigated, which showed that polyetherimide PEI-3b derived from 3,3′-BPADA and m-PDA had the lowest melt viscosity among the isomers, indicating that the melt processibility had been greatly improved.
