Kandukuri, Sandeep R.; Jiao, Lin-Yu; Machotta, Axel B.; Oestreich, Martin published an article in 2014, the title of the article was Diastereotopic group selection in hydroxy-directed intramolecular C-H alkenylation of indole under oxidative palladium(II) catalysis.Recommanded Product: (1R,2S,5R)-2-Isopropyl-5-methylcyclohexyl carbonochloridate And the article contains the following content:

Group-selective Pd(II)-catalyzed ring closures involving C-H bond alkenylation are reported. The cyclization precursors contain a prochiral bis(homoallylic) alc. unit tethered to either an arene or an indole. The homobenzylic HO group in these substrates is positioned to act as a directing group in the ortho-selective C-H bond activation prior to the cyclization event. Arene-derived precursors reacted poorly, even when applying a protocol that had proven effective in intermol. HO-directed C-H bond alkenylations. No asym. induction was obtained with chiral ligands, mono-N-protected amino acids in particular. Conversely, the cyclization of indole-derived precursors was substantially more efficient, and installation of a substituent in the benzylic position rendered these intramol. C-H bond alkenylations diastereoselective. The diastereotopic group selection is high with diastereomeric ratios ranging from dr = 91:9 to 94:6. The experimental process involved the reaction of (1R,2S,5R)-2-Isopropyl-5-methylcyclohexyl carbonochloridate(cas: 14602-86-9).Recommanded Product: (1R,2S,5R)-2-Isopropyl-5-methylcyclohexyl carbonochloridate

On July 15, 2021, Zhang, Jiuzhou; Hou, Pu; Xi, Boxuan; Lin, Wanru; Liu, Yang; Wang, Guibin; Huo, Pengfei published an article.Computed Properties of 80-07-9 The title of the article was A high energy density flexible solid-state supercapacitor based on poly (arylene ether sulfone) copolymers with polyether side chains for Li+ conducting polymer electrolytes. And the article contained the following:

To satisfy the market demand for excellent electrochem. performance, a flexible gel polymer electrolyte (GPE-EO) based on poly(arylene ether sulfone) copolymers containing polyether side chains (PAES-EO) was prepared via an ion-exchange reaction with ammonium poly(aryl ether sulfone) (PAES-N) and PEG-SO3-K+ containing EO segments. Li2SO4 was used as the electrolyte salt for the supercapacitor to obtain a wider potential window (1.5 V) and the electrochem. performance of the supercapacitors based on polymer electrolytes with or without EO segments was evaluated and analyzed. With the introduction of EO segments, the electrolyte uptake ratio of the electrolyte membrane increased to 53.29% and delivered a higher ionic conductivity of 8.26 x 10-4 S cm-1. The supercapacitor based on GPE-EO exhibits a high capacitance of 153.8 F g-1 and an energy d. of 11.67 W h kg-1 at a c.d. of 0.1 A g-1. Simultaneously, this supercapacitor based on GPE-EO possessed excellent flexibility even at a bending angle of 180° and outstanding cycle stability with negligible specific capacitance loss after 5000 cycles. This improvement of performance of gel polymer electrolytes and supercapacitors demonstrates that introducing EO segments can increase the electrochem. performance of PEAS based energy storage devices. The experimental process involved the reaction of 4,4′-Sulfonylbis(chlorobenzene)(cas: 80-07-9).Computed Properties of 80-07-9

On January 25, 2020, Sung, Seounghwa; T. S., Mayadevi; Chae, Ji Eon; Kim, Hyoung-Juhn; Kim, Tae-Hyun published an article.Reference of 4,4′-Sulfonylbis(chlorobenzene) The title of the article was Effect of increasing hydrophilic-hydrophobic block length in quaternary ammonium-functionalized poly(ether sulfone) block copolymer for anion exchange membrane fuel cells. And the article contained the following:

Quaternary ammonium-functionalized poly(ether sulfone) (QA-PES) block copolymers with different block chain lengths were prepared as anion exchange membranes. Copolymers with similar hydrophilic/hydrophobic block ratios and hence similar IEC values, but with various oligomer block chain lengths were synthesized to investigate, for the first time, how the length of each oligomer included in the block copolymers affected the chemophys. and elec. properties of the obtained QA-PES anion exchange membranes. The copolymer with the optimal hydrophilic:hydrophobic block chain length (QA-PES-16-30) showed good phase separation This led to the optimal formation of ionic clusters, and the highest ion conductivity of 81.01 mS cm-1 at 80°C, as well as excellent physicochem. stability even after alk. treatment in 1 M NaOH at 60°C for 500 h, due to strengthening of the hydrophobic regions, strongly suggesting that the block chain length of each of the hydrophilic and hydrophobic blocks can affect the physicochem. properties of the polymer membranes. The H2/O2 single cell performance using the QA-PES-16-30 membrane showed a maximum power d. of 260 mW cm-2, much higher than that obtained from the Tokuyama A201. The experimental process involved the reaction of 4,4′-Sulfonylbis(chlorobenzene)(cas: 80-07-9).Reference of 4,4′-Sulfonylbis(chlorobenzene)

Herein, a new series of polymer electrolyte membranes was prepared by chem. cross-linked poly(vinyl alc.) (PVA) and sulfonated poly(ether sulfone) (SPES). A typical polymerization reaction was conducted using three different monomers i.e. bisphenol A, phenolphthalein, and 4,4′-dichlorodiphenyl sulfone. The SPES polymer was obtained by the post-sulfonation technique using chlorosulfonic acid as a sulfonating agent. The resultant SPES polymer at different concentrations was blended with cross-linked poly(vinyl alc.). Structural anal. of the samples was conducted by FTIR, SEM, and XRD. Among the prepared PEM materials, PVA-SPES-20 blend membranes exhibited higher ion-exchange capacity and % water uptake values than those of the other membranes. In addition, the PVA-SPES-20 membrane exhibits the proton conductivity of 0.0367 S cm-1 at 30°C, whereas pristine PVA shows the proton conductivity of 0.0259 S cm-1. The overall exptl. results revealed that the PVA-SPES blend membranes are promising candidates for fuel cell applications.

On November 20, 2020, Chae, Ji Eon; Yoo, Sung Jong; Kim, Jin Young; Jang, Jong Hyun; Lee, So Young; Song, Kwang Ho; Kim, Hyoung-Juhn published an article.Recommanded Product: 80-07-9 The title of the article was Hydrocarbon-based electrode ionomer for proton exchange membrane fuel cells. And the article contained the following:

The electrode ionomer is a key factor that significantly affects the catalyst layer morphol. and fuel cell performance. Herein, sulfonated poly(arylene ether sulfone)-based electrode ionomers with polymers of various mol. weights and alc./water mixtures were prepared, and those comprising the alc./water mixture showed a higher performance than the ones prepared using higher boiling solvents, such as dimethylacetamide; this is owing to the formation of the uniformly dispersed ionomer catalyst layer. The relation between ionomer mol. weight for the same polymer structure and the sulfonation degree was investigated. Because the chain length of polymer varies with mol. weight and chain entanglement degree, its mol. weight affects the electrode morphol. As the ionomer covered the catalyst, the agglomerates formed were of different morphologies according to their mol. weight, which could be deduced indirectly through dynamic light scattering and SEM. Addnl., the fuel cell performance was confirmed in the current-voltage curve. The experimental process involved the reaction of 4,4′-Sulfonylbis(chlorobenzene)(cas: 80-07-9).Recommanded Product: 80-07-9
