Product Details of 623-24-5In 2021 ,《Stable Solid Electrolyte Interphase Formation Induced by Monoquat-Based Anchoring in Lithium Metal Batteries》 was published in ACS Energy Letters. The article was written by Zhou, Tianhong; Zhao, Yan; El Kazzi, Mario; Choi, Jang Wook; Coskun, Ali. The article contains the following contents:

The lithium (Li) metal anode is considered to be a promising candidate for next-generation batteries but is impeded by Li dendrites and the resulting poor reversibility. Here, monoquat salts are introduced with an ability to anchor onto the Li metal surface through pyridine moieties as electrolyte additives. Both the number and the spatial arrangement are systematically varied of anchoring units along with the number of pos. charges bearing PF6 counter anions to probe their impact on Li metal protection. A high surface concentration of PF6 counter anions and their immediate reaction with the deposited Li facilitate the in situ formation and homogeneous distribution of LiF in the surface passivation layer. The results revealed that the monoquat dication, through stable pyridine-based anchoring, formed an ionically conductive and dense solid electrolyte interphase layer and showed superior cycling performance in both ether-based and carbonate-based electrolytes, thus clearly demonstrating the importance of the anchoring strategy for Li metal surface protection. In the experiment, the researchers used 1,4-Bis(bromomethyl)benzene(cas: 623-24-5Product Details of 623-24-5)

The author of 《The high performance of polyaniline-gel network modified electrode in 3-(2,2,6,6-tetramethyl-piperidiynl-1-oxyl)-1-methylylimidazoliumbromide biredox electrolyte used for supercapacitor》 were Wang, Kui; Wang, Jixiao; Zhao, Song; Wang, Zhi; Wang, Shichang. And the article was published in Journal of Power Sources in 2019. SDS of cas: 623-24-5 The author mentioned the following in the article:

Improving energy d. while maintaining power d. and cycle stability is the most serious challenge for supercapacitors. The solid active electrode material might possess a higher redox species d. compared with its traditional counterpart, however, its electrochem. reaction kinetics is several magnitude orders lower in solids than that in liquids, leading to a deterioration of power d. Thus, a new approach based on 3-TEMPO-1-methylylimidazolium bromide (MIm+-TEMPO• Br-) biredox electrolyte, and a PANI-gel network modified carbon paper (PNcp) electrode for supercapacitor were developed. The biredox electrolyte possesses a high energy d. comparable to solid redox materials and a fast kinetics of liquid redox reaction, while the cross-diffusion of ions leads to a serious voltage drop which presents an inherent self-discharge problem. Fortunately, the PNcp prepared by a millisecond photo-thermal process makes up for this shortcoming. On one hand, its unique PANI-gel network structure protects the biredox electrolyte from cross-diffusion phenomenon, however, the combination of doping/dedoping process of PANI and redox process of MIm+-TEMPO• Br- provides an extra effect to prevent the self-discharge and attain a synergetic electrochem. performance. This method explores an avenue to pursue for battery level energy d. meanwhile maintains good power d. In addition to this study using 1,4-Bis(bromomethyl)benzene, there are many other studies that have used 1,4-Bis(bromomethyl)benzene(cas: 623-24-5SDS of cas: 623-24-5) was used in this study.

1,4-Bis(bromomethyl)benzene(cas: 623-24-5) belongs to organobromine compounds.Depending on the type of carbon to which the bromine is bonded, organic bromide could be alkyl, alkenyl, alkynyl, or aryl. SDS of cas: 623-24-5 Due to the reactivity of bromide, they are used as potential precursors or important intermediates in organic synthesis.

The author of 《Interchain doubly-bridged α-helical peptides for the development of protein binders》 were Chen, Yaqi; Liang, Jingjing; Li, Tao; Lin, Ping; Zhao, Yibing; Wu, Chuanliu. And the article was published in Chinese Chemical Letters in 2019. Computed Properties of C8H8Br2 The author mentioned the following in the article:

Constrained peptide scaffolds that are tolerant to extensive sequence manipulation and amenable to bioactive peptide design are of great value to the development of novel protein binders and peptide therapeutics. The authors reported strategies for the design and synthesis of a kind of novel interchain doubly-bridged α-helical peptides, involving mutual stabilization of two peptide α-helixes linked by two interchain bisthioether crosslinkers. By taking a MDM2-binding peptide with an α-helical tendency as a model, α-helical dimers with significantly improved structural and proteolytic stability and nanomolar binding affinity to the target protein can be obtained. By modulating the surface charges on the dimeric peptides, the authors also obtained a dimeric peptide with enhanced cell-penetrating capability, which can efficiently penetrate into cancer cells and inhibit the intracellular MDM2-p53 interactions to promote cell apoptosis. Considering that many proteins take a surface α-helical segment as the binding motif to mediate their interactions with other proteins, the authors believe that the authors’ interchain doubly-bridged α-helical peptides would provide a promising scaffold for the development of novel high-affinity protein binders.1,4-Bis(bromomethyl)benzene(cas: 623-24-5Computed Properties of C8H8Br2) was used in this study.

In 2022,Singh, Varinder; Abudayyeh, Abdullah M.; Robb, Matthew G.; Brooker, Sally published an article in Dalton Transactions. The title of the article was 《Mono-copper far more active than analogous di-copper complex for electrocatalytic hydrogen evolution》.Recommanded Product: 623-24-5 The author mentioned the following in the article:

The di-copper(II) analog, [CuII2(bis-LEt)](BF4)2 (2), of the previously reported mono-copper(II) complex [CuIILEt]BF4 (1) which resulted in long lived electrocatalytic hydrogen evolution reaction (HER), has been prepared, characterised and tested for HER. The new bis-macrocycle, bis-HLEt, was formed from two HLEt Schiff base macrocycles (prepared by 1 + 1 condensation of 2,2′-iminobisbenzaldehyde and diethylenetriamine) being connected by selective alkylation of the less sterically hindered secondary alkyl amine group (NH) of each, using α,α′-dibromo-para-xylene to form a linker between them. The desired dicopper(II) complex, [Cu2II(bis-LEt)](BF4).4H2O (2.4H2O), was readily prepared, as a yellowish brown solid in 82% yield. SCXRD on yellow-brown crystals of [CuII2(bis-LEt)](BF4)2.2MeCN (2.2MeCN) revealed both copper(II) centers are square planar with a very similar copper(II) coordination environment to that of square planar 1. Although dicopper(II) complex 2 is easier to reduce than the analogous monocopper(II) complex 1 in MeCN (E1/2(ΔE): 2 -1.20(0.12) V, 1 -1.39(0.09) V, vs. 0.01 M AgNO3/Ag), electrocatalytic HER testing of dicopper complex 2·4H2O, in MeCN with 80 equiv of acetic acid, revealed it was inactive, in stark contrast to the high and ongoing activity of 1 under the same conditions. So two is definitely not better than one metal ion in this case. Rather, it may be that the presence of an NH group in the macrocycle of 1, but absent in the bis-macrocycle of 2 (due to alkylating that NH to link the two macrocycles), may be key to the HER activity seen for 1.

In 2019,Chinese Chemical Letters included an article by Zhang, Ding; Sha, Min; Pan, Renming; Lin, Xiangyang; Xing, Ping; Jiang, Biao. Application In Synthesis of 1,4-Bis(bromomethyl)benzene. The article was titled 《Design and synthesis of the novel branched fluorinated surfactant intermediates with CF3CF2CF2C(CF3)2 group》. The information in the text is summarized as follows:

Perfluorooctanoic acid (PFOA) or perfluorooctane sulfonate (PFOS) was one of the most prominent fluorosurfactants and applied widely in fire-fighting and daily chem., etc. However, these surfactants have recently been identified as toxic and undegradability in the environment. Developing an efficient approach to environment-friendly fluorosurfactants is essential. A fluorocarbon branched chain strategy was adopted to develop /PFOS substitutes. A series of intermediates of novel branched fluorinated surfactants with CF3CF2CF2C(CF3)2 group were synthesized from perfluoro-2-methyl-2-pentene. All the steps were mild, easy-handled and cheap. It is expected to be a very significant direction for the development of non-bioaccumulable alternatives of PFOA or PFOS.

The article was titled 《Construction of a cationic organic network for highly efficient removal of anionic contaminants from water》. The information in the text is summarized as follows:

Widespread water contamination has become a great threat to human survival, and therefore developing an efficient strategy for decontamination of wastewater is of great significance. Herein, a new cationic organic network (CON-1) has been constructed by a facile method from com. available precursors, 1,4-bis(bromomethyl)benzene (BBMB) and 5,10,15,20-tetra(4-pyridyl)porphyrin (TPP), via a quaternization reaction. After being well characterized, CON-1 was employed as an adsorbent for removal of anionic contaminants in aqueous media. Benifitting from the charged framework and exchangeable counter ions, CON-1 exhibits fast adsorption kinetics and high adsorption capacity towards organic dyes and dichromate. The maximum adsorption capacity for the organic dye orange G and Cr2O72- can reach up to 718 mg g-1 and 293 mg g-1, resp. Moreover, CON-1 displays good stability in the adsorption process, it can be regenerated and it can be reused for several cycles. The facile synthesis, high efficiency, and good stability endow CON-1 with great potential in the purification of wastewater.

Quality Control of 1,4-Bis(bromomethyl)benzene The article mentions the following:

Finding efficient actinide decorporation agents is crucial for public health and the development of the nuclear industry. The current inventory of decorporation agents is predominately limited to a handful of ligands. In this work, a two-dimensional (2D) covalent organic nanosheet (CON) material was rationally designed and tested for in vivo uranium decorporation. This material is extensively grafted with amidoxime (AO), a classic uranium-recognition ligand, which not only provides selective binding sites for uranyl but also expands the interlayer spacing of CON, making the active sites more accessible. Significantly, the results of in vivo experiments demonstrate that, in both prophylactic and prompt administration groups, CON-AO exhibits a higher excretion ratio of uranium from kidneys than that of ZnNa3-diethylenetriamine pentaacetate (DTPA), while presenting a similar level of cytotoxicity. These results suggest that functionalized CONs may emerge as a promising type of actinide in vivo decorporation agent.

In 2022,Li, Wanjiang; Chen, Longbin; Dong, Jiao; Feng, Yancong; Wang, Yao; Li, Hao; Zhou, Guofu published an article in ACS Applied Polymer Materials. The title of the article was 《Water- and Heat-Induced Crack-Healing of UCST-Type Poly(acrylamide-co-acrylonitrile) with Intrinsic Controllability and Reversibility》.Application of 623-24-5 The author mentioned the following in the article:

Autonomic crack-healing technol. has become a common option for reconstructing polymer networks against mech. degradation, structure mismatch, material fatigue, and even performance failure, but how to precisely and easily trigger this healing process on the crack interfaces is still a huge challenge. Here, we first found an autonomic physicochem. crack-healing behavior featuring intrinsic controllability and reversibility, based on nonionic poly(acrylamide-co-acrylonitrile) [P(AAm-co-AN)] with an upper critical solution temperature (UCST). Under the fast synergistic action between extrinsic deionized water and heat, the scratched P(AAm-co-AN) layer fully returned to the original flat form and was reworked at least five times. Meanwhile, their corresponding optical and mech. performances also recovered almost 100%. In particular, the intrinsic thermoresponsiveness of P(AAm-co-AN) takes a leading role in this crack-healing process, in which both interchain transition and topol. entanglement come into play. It provides a facile, rapid, precise, green, and autonomic crack-healing strategy for improving polymer durability. The results came from multiple reactions, including the reaction of 1,4-Bis(bromomethyl)benzene(cas: 623-24-5Application of 623-24-5)

These research results belong to Li, Jing; Han, Yulan; Lin, Han; Wu, Nanhua; Li, Qinkun; Jiang, Jun; Zhu, Jiahua. Recommanded Product: 1,4-Bis(bromomethyl)benzene The article mentions the following:

Cobalt-salen-based porous ionic polymers, which are composed of cobalt and halogen anions decorated on the framework, effectively catalyze the CO2 cycloaddition reaction of epoxides to cyclic carbonates under ambient conditions. The cooperative effect of bifunctional active sites of cobalt as the Lewis acidic site and the halogen anion as the nucleophile responds to the high catalytic performance. Moreover, d. functional theory results indicate that the cobalt valence state and the corresponding coordination group influence the rate-determining step of the CO2 cycloaddition reaction and the nucleophilicity of halogen anions.
