Reference of 1,4-Bis(bromomethyl)benzene. The article was titled 《Two-Dimensional Cationic Networks and Their Spherical Curvature with Tunable Opening-Closing》. The information in the text is summarized as follows:

Despite many cationic nanomaterials that have been developed for efficient adsorption of anionic pollutants, tailoring a stable shape with denser cations on the surface for advanced removal capability remains challenging. Here, a new strategy is presented for fabricating two-dimensional (2D) cationic laminas and their curvature based on crosslinking of 2D supramol. networks from hydrogen-bonded trimesic amide derivatives Owing to the distribution of most cations on the surface, two cationic nanostructures from crosslinking of supramol. networks show fast sorption kinetics for anionic pollutants. Notably, the removal capacity of the capsule-like curvature adsorbent is more than twice that of lamina adsorbent for sufficient space around cationic sites in hollow aperture. Moreover, the capsule-like adsorbent is triggered to open and spontaneously release the adsorbed pollutants upon the addition of halogen anions, which can be recovered by subsequent dialysis. Strategy of a capsule-like pocket with tunable opening-closing will provide a new insight for storage and adsorption.

The article conveys some information:

Triplet excited-state organic chromophores present countless opportunities for applications in photocatalysis. Here we describe an approach to the engineering of the triplet excited states of aromatic chromophores, which involves incorporating pyrene into pyridinium-containing mech. interlocked mols. (MIMs). The π-extended nature of the pyrenes enforces [π···π] stacking, affording an efficient synthesis of tetrachromophoric octacationic homo[2]catenanes. These MIMs generate triplet populations and efficient intersystem crossing on account of the formation of a mixed charge-transfer/exciplex electronic state and a nanoconfinement effect, which leads to a high level of protection of the triplet state and extends the triplet lifetimes and yields. These compounds display excellent catalytic activity in photo-oxidation, as demonstrated by the aerobic oxidation of a sulfur-mustard simulant. This research highlights the benefits of using the mech. bond to fine-tune the triplet photophysics of existing aromatic chromophores, providing an avenue for the development of unexplored MIM-based photosensitizers and photocatalysts.

The article conveys some information:

Titanosilicate zeolites are catalysts of interest in the field of fine chems. However, the generation and accessibility of active sites in titanosilicate materials for catalyzing reactions with large mols. is still a challenge. Herein, we prepared titanosilicate zeolite precursors with open zeolitic structures, tunable pore sizes, and controllable Si/Ti ratios through a hydrothermal crystallization strategy by using quaternary ammonium templates. A series of quaternary ammonium ions are discovered as effective organic templates. The prepared amorphous titanosilicate zeolites with some zeolite framework structural order have extra-large micropores and abundant octahedrally coordinated isolated Ti species, which lead to a superior catalytic performance in the oxidative desulfurization of dibenzothiophene (DBT) and epoxidation of cyclohexene. It is anticipated that the amorphous prezeolitic titanosilicates will benefit the catalytic conversion of bulky mols. in a wide range of reaction processes.1,4-Bis(bromomethyl)benzene(cas: 623-24-5COA of Formula: C8H8Br2) was used in this study.

In 2019,Chemical Science included an article by Zhou, Jiawang; Wu, Yilei; Roy, Indranil; Samanta, Avik; Stoddart, J. Fraser; Young, Ryan M.; Wasielewski, Michael R.. Formula: C8H8Br2. The article was titled 《Choosing sides: unusual ultrafast charge transfer pathways in an asymmetric electron-accepting cyclophane that binds an electron donor》. The information in the text is summarized as follows:

Constructing functional mol. systems for solar energy conversion and quantum information science requires a fundamental understanding of electron transfer in donor-bridge-acceptor (D-B-A) systems as well as competitive reaction pathways in acceptor-donor-acceptor (A-D-A) and acceptor-donor-acceptor’ (A-D-A’) systems. Herein we present a supramol. complex comprising a tetracationic cyclophane having both phenyl-extended viologen (ExV2+) and dipyridylthiazolothiazole (TTz2+) electron acceptors doubly-linked by means of two p-xylylene linkers (TTzExVBox4+), which readily incorporates a perylene (Per) guest in its cavity (Per ⊂ TTzExVBox4+) to establish an A-D-A’ system, in which the ExV2+ and TTz2+ units serve as competing electron acceptors with different reduction potentials. Photoexcitation of the Per guest yields both TTz+·- Per+·- ExV2+ and TTz2+-Per+·-ExV+·in < 1 ps, while back electron transfer in TTz2+-Per+·-ExV+· proceeds via the unusual sequence TTz2+-Per+· -ExV+· →TTz+· -Per+· -ExV2+ → TTz2+-Per-ExV2+. In addition, selective chem. reduction of TTz2+ gives Per ⊂ TTzExVBox3+· turning the complex into a D-B-A system in which photoexcitation of TTz+· results in the reaction sequence 2*TTz+· -Per-ExV2+ → TTz2+-Per-ExV+ → TTz +· -Per-ExV2+. Both reactions TTz2+-Per+· -ExV+· → TTz+ -Per+· -ExV2+ and TTz2+-Per-ExV+· → TTz+· -Per-ExV2+ occur with a (16 ± 1 ps)-1 rate constant irresp. of whether the bridge mol. is Per+ or Per. These results are explained using the superexchange mechanism in which the ionic states of the perylene guest serve as virtual states in each case and demonstrate a novel supramol. platform for studying the effects of bridge energetics within D-B-A systems.1,4-Bis(bromomethyl)benzene(cas: 623-24-5Formula: C8H8Br2) was used in this study.

《An efficient hydrogenation catalytic model hosted in a stable hyper-crosslinked porous-organic-polymer: from fatty acid to bio-based alkane diesel synthesis》 was published in Green Chemistry in 2020.

Name: 1,4-Bis(bromomethyl)benzene The article mentions the following:

In this study, a Pd-based catalytic model over a nitrogen enriched fibrous Porous-Organic-Polymer (POP) is established to execute hydrodeoxygenation of various vegetable oils in producing potential large-scale renewable diesel. Here we report a cost-effective synthesis strategy for a new microporous hypercrosslinked POP through the FeCl3 assisted Friedel-Crafts alkylation reaction, followed by fabrication of Pd0-NPs (2-3 nm) using a solid gas phase hydrogenation route to deliver a novel catalytic system. This catalyst (called Pd@PPN) exhibits versatile catalytic performance for different types of vegetable oils including palm oil, soybean oil, sunflower oil and rapeseed oil to furnish long chain diesel range alkanes. The catalyst is comprehensively characterized using various spectroscopic tools and it shows high stability during five runs of recycling without leaching of Pd. Our results further reveal that a direct decarbonylation (DCN) pathway of fatty acids to produce alkanes with one fewer carbon is the dominant mechanism. Under optimized conditions, using stearic acid to represent the long linear carboxylic acids in the vegetable oils, up to 90% conversion with 83% selectivity of C17-alkane has been achieved on our fabricated catalyst. D. functional theory (DFT) calculations are performed to provide insights into the electronic properties of the catalyst, the mechanistic reaction pathway, the crucial role of the catalyst surface and the product selectivity trend. The strong interaction between the corrugated polymer-frame-structure and the Pd-NPs suggests the presence of high d. step sites on the fabricated Pd-NP anchored within the cage of the polymer structure. DFT calculations also reveal the strong promotional effect of step sites and charge transfer in facilitating rate-limiting steps during the decarbonylation (DCN) pathway and removal of strongly bound intermediates formed during the process, therefore explaining the high activity of the fabricated Pd@PPN catayst for the hydrodeoxygenation (HDO) conversion to produce bio-based alkane diesel.

《Cationic ether-free poly(bis-alkylimidazolium) ionene blend polybenzimidazole as anion exchange membranes》 was written by Dong, Jianhao; Yu, Na; Che, Xuefu; Liu, Ruihong; Aili, David; Yang, Jingshuai. SDS of cas: 623-24-5 And the article was included in Polymer Chemistry in 2020. The article conveys some information:

Two ether-free poly(bis-alkylimidazolium) ionenes with imidazolium cations as part of the main chain were synthesized from 1,4-bis(imidazolyl)butane and 1,4-dibromobutane or 1,4-bis(bromomethyl)benzene via nucleophilic substitution polymerization Anion exchange membranes (AEMs) were prepared by co-casting with polybenzimidazole (PBI), producing visually homogeneous and mech. robust blend AEMs. The ion exchange capacity (IEC), water uptake and ion conductivity could be balanced by adjusting the molar ratio of the poly(bis-alkylimidazolium) to PBI polymer in the blend. For example, the blend AEM of PBuIm-37%/PBI prepared from the oligomer derived from 1,4-dibromobutane with an IEC of 1.36 mmol g-1 showed a tensile strength of 5.3 MPa at room temperature and a hydroxide conductivity of 74 mS cm-1 at 80 °C and excellent stability over 500 h in 1 mol L-1 KOH at 60 °C.

Jiang, Huimin; Yan, Liting; Zhang, Shuo; Zhao, Yanchao; Yang, Xue; Wang, Yameng; Shen, Jianxing; Zhao, Xuebo; Wang, Lianzhou published an article in 2021. The article was titled 《Electrochemical surface restructuring of phosphorus-doped carbon@MoP electrocatalysts for hydrogen evolution》, and you may find the article in Nano-Micro Letters.SDS of cas: 623-24-5 The information in the text is summarized as follows:

The hydrogen evolution reaction (HER) through electrocatalysis is promising for the production of clean hydrogen fuel. However, designing the structure of catalysts, controlling their electronic properties, and manipulating their catalytic sites are a significant challenge in this field. Here, we propose an electrochem. surface restructuring strategy to design synergistically interactive phosphorus-doped carbon@MoP electrocatalysts for the HER. A simple electrochem. cycling method is developed to tune the thickness of the carbon layers that cover on MoP core, which significantly influences HER performance. Exptl. investigations and theor. calculations indicate that the inactive surface carbon layers can be removed through electrochem. cycling, leading to a close bond between the MoP and a few layers of coated graphene. The electrons donated by the MoP core enhance the adhesion and electronegativity of the carbon layers; the neg. charged carbon layers act as an active surface. The electrochem. induced optimization of the surface/interface electronic structures in the electrocatalysts significantly promotes the HER. Using this strategy endows the catalyst with excellent activity in terms of the HER in both acidic and alk. environments (c.d. of 10 mA cm-2 at low overpotentials, of 68 mV in 0.5 M H2SO4 and 67 mV in 1.0 M KOH).

《N -Methylated 1,8-Diaminonaphthalenes as Bifunctional Nucleophiles in Reactions with α,ω-Dihalogenoalkanes: A Facile Route to Heterocyclic and Double Proton Sponges》 was published in Synthesis in 2020. These research results belong to Kolupaeva, Ekaterina V.; Ozeryanskii, Valery A.; Pozharskii, Alexander F.. SDS of cas: 623-24-5 The article mentions the following:

The reaction of 1-dimethylamino-8-(methylamino)naphthalene with 1,3-dibromopropane chemoselectively leaded to the product of N, N’-heterocyclization, while in the case of 1,4-dibromobutane and 1,2-bis(bromomethyl)benzene the process resulted in heterocyclization onto the same nitrogen atom with the formation of previously unknown 1-dimethylamino-8-pyrrolidino- and 1-dimethylamino-8-isoindolino-naphthalenes. The same reactions conducted without adding any auxiliary base leaded to the formation of N, N’-linked double proton sponges as a new type of polynitrogen organic receptor. Proceeding as a sequence of quaternization-demethylation-cyclization steps, this heterocyclization process was used to construct six-membered rings (piperidino, morpholino), albeit in lower yields. The ability of 1,2-dibromoethane to brominate N-alkylated 1,8-diaminonaphthalenes was described. It is shown for the first time that a com. available 1,8-bis(dimethylamino)naphthalene (DMAN) can be used as a starting material in a heterocyclization reaction, which via a one-pot approach and in a short time can be converted into 1,5-dimethylnaphtho[1,8- bc]-1,5-diazacyclooctane or 1-dimethylamino-8-(pyrrolidin-1-yl)naphthalene.

The author of the article were Sharma, Sandeep; Ntetsikas, Konstantinos; Ladelta, Viko; Bhaumik, Saibal; Hadjichristidis, Nikos. The article conveys some information:

The synthesis of cyclic polymers on a large scale is a challenging task for polymer scientists due to the requirement of ultra-high dilution conditions. In this paper, we demonstrate an alternative method to prepare cyclic polymers with moderate dilution and up to 1 g scale. We employed a simple Williamson etherification reaction to prepare cyclic polymers with a good solvent/non-solvent combination. In this way, various polystyrene (PS) and polyethylene glycol (PEG) cyclic homopolymers were synthesized. Anionic polymerization using high vacuum techniques combined with the postpolymn. reaction was used to generate linear dihydroxy PS precursors. The synthesized linear and cyclic homopolymers were fully characterized using various spectroscopic and anal. techniques, such as size exclusion chromatog. (SEC), matrix-assisted laser desorption/ionization time-of-flight mass spectroscopy (MALDI-TOF-MS), and differential scanning calorimetry (DSC). Detailed NMR spectroscopic studies were also performed to obtain the complete structural information of the synthesized polymers.
