And the article contained the following:

Lanthanide coordinating polymeric microparticles are considered as versatile building blocks for construction of various advanced functional materials and devices, but the research involving the modulation of their fine morphol., luminescence properties and processability is still limited. Herein, we have synthesized an amphiphilic aromatic multi-block copolymer (abbreviated as amPENS) showing intrinsic blue fluorescence emission, which was further employed as a coordination ligand to sensitize the intrinsic fluorescence emission of Tb3+ and Eu3+. Specifically, the three dimensional (3D) emulsion confinement self-assembly of amPENS with lanthanide ions was explored to fabricate sub-micron sized Ln-PENS microparticles, whose fluorescence emission and surface morphol. can be readily tuned via the concentration of amPENS and lanthanide ions, as well as stirring speed during emulsion self-assembly. More importantly, we further proved that the Ln-PENS doped polyvinyl alc. (PVA) solution can be processed into multi-band emissive fluorescent nanofibers coatings via electrospinning. Basically, the current work reveals a new strategy to design lanthanide coordination polymeric superparticles with tunable morphol. and fluorescence, which would open the way for fabrication of advanced lanthanide based materials for various applications such as sensing, anti-counterfeiting, information recording and optoelec. devices. The experimental process involved the reaction of 4,4′-Sulfonylbis(chlorobenzene)(cas: 80-07-9).Recommanded Product: 4,4′-Sulfonylbis(chlorobenzene)

On November 1, 2020, Gronwald, Oliver; Frost, Inga; Ulbricht, Mathias; Kouchaki Shalmani, Arman; Panglisch, Stefan; Gruenig, Lara; Handge, Ulrich A.; Abetz, Volker; Heijnen, Martin; Weber, Martin published an article.Electric Literature of 80-07-9 The title of the article was Hydrophilic poly(phenylene sulfone) membranes for ultrafiltration. And the article contained the following:

Poly(alkylene oxide) based tri- and multiblock oligomers with hydrophobic poly(phenylene sulfone) blocks were evaluated as dope solution additives used for preparation of improved poly(phenylene sulfone) (PPSU) flat sheet (FS) and single bore (SB) ultrafiltration membranes by non-solvent induced phase separation (NIPS). Identical polymer dope recipes were used in both of FS membrane preparation and SB fiber spinning processes. PPSU membranes modified with 9.2 wt % Pluronic F127 based additive, M2 (7.5 kDa PPSU/ Pluronic F127), or Lutensol AT80 based additive, T2 (7.5 kDa PPSU/ Lutensol AT80), displayed compared to pristine PPSU membranes elevated hydraulic permeance ranging from 485 to 674 kg m-2 bar-1h-1 (pristine PPSU: 310 – 464 kg m-2 bar-1h-1), higher mol. weight cut-off values from 37.0 to 53.5 kDa (pristine PPSU: 21.4 – 23.7 kDa), lower contact angles of 46.4° and 49.8° (pristine PPSU: 86.7°) and reduced fouling propensity with irreversible fouling values of 10% (pristine PPSU: 15%) for diluted potting soil extract as model substance. The combined anal. methods of XPS and proton NMR spectroscopy (1H NMR) indicated modest surface enrichment of the additives in the filtration layer. Consequently, PPSU ultrafiltration membranes modified with additives T2 and M2 provide interesting alternatives to poly(ether sulfone) (PESU) and poly(vinylidene fluoride) (PVDF) based membranes for surface water filtration combining both excellent filtration characteristics with a long lifetime due to its higher chem. resistance.

On April 1, 2020, Wang, Jing; Liu, Yapin; Liu, Tao; Xu, Xingmin; Hu, Yunxia published an article.Name: 4,4′-Sulfonylbis(chlorobenzene) The title of the article was Improving the perm-selectivity and anti-fouling property of UF membrane through the micro-phase separation of PSf-b-PEG block copolymers. And the article contained the following:

PSf-b-PEG block copolymers with different PEG contents were synthesized to fabricate the highly permselective and antifouling ultrafiltration (UF) membranes. PEG homopolymer was also blended into the polysulfone casting solutions to fabricate the control (PSf/PEG blend) membranes. The membrane pore structure, surface properties and separation performances of PSf-b-PEG block copolymer membranes and PSf/PEG blend membranes were investigated to identify the role of PEG block for the pore formation. Our results find that the higher PEG content in the PSf-b-PEG block copolymer and in the PSf/PEG blend system was favorable to form more pores and thinner top skin layer with the slightly larger pore size and the higher MWCO of the fabricated membranes. But under the same content, PEG in the block copolymer could help to generate more pores but with similar pore size than PEG in the blend system during the phase-inversion process, which is because of the micro-phase separation of PSf block and PEG block. The fabricated PSf-b-PEG21 (PSf-b-PEG having 21 wt% PEG) membrane had a high water permeation coefficient of 980.0 ± 33.0 LMH/bar and a high BSA rejection above 98%, succeeding the current permselectivity upper-bound of the reported polymeric UF membranes. Antifouling experiments confirmed that the PSf-b-PEG21 membrane exhibited a slow and less flux decline during the fouling stage, but a fast and high flux recovery after the backwash cleaning. Our work provides some insights on the relationship of PSf-b-PEG block copolymer composition and membrane structure-separation properties.

On July 1, 2020, Liao, Junbin; Chen, Quan; Pan, Nengxiu; Yu, Xinyan; Gao, Xing; Shen, Jiangnan; Gao, Congjie published an article.Quality Control of 4,4′-Sulfonylbis(chlorobenzene) The title of the article was Amphoteric blend ion-exchange membranes for separating monovalent and bivalent anions in electrodialysis. And the article contained the following:

It is of significant importance to develop highly monovalent anion-selective membranes (MASM) having stable structure for a wide range of applications. To realize the efficient monovalent/bivalent anion separation, in this work, three amphoteric ion-exchange membranes (AIEMs) through blending were fabricated for use in electrodialysis (ED). The three membranes were prepared by blending amino-containing poly(arylene ether sulfone) (PAES-NH2) with 10, 15, and 20 wt% of sulfonated polysulfone (SPSf), resp., followed by grafting imidazolium salt-terminated side alkyl chains on PAES backbone. Our investigations demonstrate that each transparent AIEM shows good miscibility between the two components, which has been verified by a homogeneous structure via SEM observation and by an even distribution of N element via EDX mapping. In the ED process at a c.d. of 2.5 mA cm-2, AIEM with 15 wt% of SPSf shows the superior perm-selectivity (Cl-/SO-24) of 21.8, relative to many reported MASMs having modified surfaces (<6.0), which is synergistically contributed by (i) electrostatic repulsion difference from the neg.-charged sulfonate groups against monovalent Cl- ions and bivalent SO-24 ions and (ii) hydrated energy difference of hydrated Cl-/SO-24 ions. This work thus presents a strategy to guide the architectural design of advanced MASMs. The experimental process involved the reaction of 4,4'-Sulfonylbis(chlorobenzene)(cas: 80-07-9).Quality Control of 4,4′-Sulfonylbis(chlorobenzene)

On December 8, 2020, Nugraha, Adam F.; Kim, Songmi; Shin, Sung-Hee; Lee, Hyejin; Shin, Dongwon; Bae, Byungchan published an article.Related Products of 80-07-9 The title of the article was Chemically Durable Poly(phenylene-co-arylene ether) Multiblock Copolymer-Based Anion Exchange Membranes with Different Hydrophobic Moieties for Application in Fuel Cells. And the article contained the following:

Quaternized multiblock poly(phenylene-co-arylene ether)s (QPPs) are synthesized from a pre-aminated monomer and a series of chlorine-terminated oligo(arylene-ethers) via a nickel coupling reaction. Their properties are investigated as anion exchange membranes with the goal of obtaining membranes with enhanced performance and durability for alk. membrane fuel cell applications. Three different oligo(arylene ethers) were synthesized and introduced in the hydrophobic block of the polymer backbone to study its effect on the membrane properties. The chloride ion conductivity of the QPP membranes was significantly less dependent on the humidity compared to that of the com. Fumatech membrane due to the well-defined hydrophilic-hydrophobic phase separation, as confirmed by TEM. An accelerated alk. stability test indicated that the QPPs were more stable than the com. Fumatech membrane up to 1700 h. The QPP-6F membrane shows an alk. membrane fuel cell single-cell performance with a maximum power d. of 534 mW cm-2 at 70°C. The experimental process involved the reaction of 4,4′-Sulfonylbis(chlorobenzene)(cas: 80-07-9).Related Products of 80-07-9

On July 15, 2020, Zhang, Zhenguo; Ren, Jiahui; Xu, Jingmei; Wang, Zhe; He, Wenwen; Wang, Shuang; Yang, Xudong; Du, Xinming; Meng, Lingxin; Zhao, Pengyun published an article.Recommanded Product: 4,4′-Sulfonylbis(chlorobenzene) The title of the article was Adjust the arrangement of imidazole on the metal-organic framework to obtain hybrid proton exchange membrane with long-term stable high proton conductivity. And the article contained the following:

Metal-organic frameworks-based hybrid proton exchange membranes could combine the advantages of organic and inorganic materials with excellent chem. and phys. stability and good proton conductivity In this work, two kinds of functionalized MOFs were synthesized based on MOF-801. Imidazole@MOF-801 was prepared by the impregnation method, which mainly incorporated free imidazole mols. into the pores of the MOF-801. Imidazole-MOF-801 was obtained by in-situ method, which imidazole further acted as non-structural ligands to coordinate to the zirconium metal sites. Furthermore, the hybrid membranes were fabricated with synthesized MOFs as fillers and sulfonated poly (arylene ether ketone sulfone) containing carboxyl groups (C-SPAEKS) as organic matrix. The structures and morphologies of the prepared MOFs and hybrid membranes were characterized by 1H NMR, XRD, FT-IR and SEM. The PXRD results showed that Im@MOF-801 and Im-MOF-801 exhibited excellent stabilities in both water and acid. The proton conductivities of these hybrid membranes were much higher (0.023-0.066 S cm-1 at 30°C, 0.050-0.128 S cm-1 at 90°C) than that of pure C-SPAEKS (0.010S cm-1 at 30°C, 0.024 S cm-1 at 90°C). Moreover, C-SPAEKS/Im-MOF-801-4% could maintain a stable proton conductivity for more than 100 h. These results indicate that these hybrid membranes have potential as proton exchange membranes. The experimental process involved the reaction of 4,4′-Sulfonylbis(chlorobenzene)(cas: 80-07-9).Recommanded Product: 4,4′-Sulfonylbis(chlorobenzene)

And the article contained the following:

In this research, poly(aryl ether sulfone sulfide) was synthesized by nucleophilic aromatic substitution reaction of 4,4′-thiodiphenol with 4,4′-dichlorodiphenyl sulfone in the presence of potassium carbonate. Also, flower-like zinc oxide nanoparticles were synthesized through sol-gel route and then added in various percentages to poly(aryl ether sulfone sulfide) matrix to modify its hydrophobic nature. The chem. structure of the polymer was confirmed using Fourier transform IR and proton NMR spectroscopy. For investigation of thermal properties of the samples, differential scanning calorimetry and thermogravimetric anal. were applied. Hydrophilicity of the membranes was also studied via contact angle measurement. Morphol. of membranes and distribution of flower-like zinc oxide nanoparticles that were followed by SEM and transmission electron microscopy showed asym. structure with porous sub-layer and dense skin layer. Pure water flux, salt rejection, and flux recovery ratio also were investigated using cross-flow filtration system with NaCl as a feed solution Effect of zinc oxide on polysulfone matrix was studied. The results showed that presence of ZnO modified the mech. and thermal properties of samples. Maximum pure water flux (61 L m-2 h-1), salt rejection (63.6%), and flux recovery ratio (77.6%)were related to the sample with 3 wt% zinc oxide. The experimental process involved the reaction of 4,4′-Sulfonylbis(chlorobenzene)(cas: 80-07-9).Formula: C12H8Cl2O2S
