The article conveys some information:

For achieving high-performance p-i-n perovskite solar cells (PSCs), hole transporting materials (HTMs) are critical to device functionality and represent a major bottleneck to further enhancing device stability and efficiency in the inverted devices. Three dopant-free polymeric HTMs are developed based on different linkage sites of triphenylamine and phenylenevinylene repeating units in their main backbone structures. The backbone curvatures of the polymeric HTMs affect the morphol. and hole mobility of the polymers and further change the crystallinity of perovskite films. By using PTA-mPV with moderate mol. curvature, p-i-n PSCs with high efficiency of 19.5% and long-term stability can be achieved. The better performance is attributed to the more effective hole extraction ability, higher charge-carrier mobility, and lower interfacial charge recombination. Furthermore, these three polymeric HTMs are synthesized without any noble metal catalyst, and show great advantages in future application owing to the low-cost. In the experiment, the researchers used many compounds, for example, 1,4-Bis(bromomethyl)benzene(cas: 623-24-5Recommanded Product: 623-24-5)

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. Dehydrobromination, Grignard reactions, reductive coupling, Wittig reaction, and several nucleophilic substitution reactions are some of the principal reactions which involve organic bromides.

Safety of 1,4-Bis(bromomethyl)benzeneIn 2020 ,《Synthesis and properties of a stimulus-responsive block polymer》 was published in RSC Advances. The article was written by Wang, B.; Liu, F. Q.. The article contains the following contents:

In this study, the synthesis of small mols. and use of an improved “”one-pot”” method to synthesize the reversible addition-fragmentation chain transfer polymerization (RAFT) reagents have been reported. By comparing with the RAFT reagents synthesized by the traditional “”step-by-step”” method, it was observed that the reagents synthesized by the two methods had the same structure, however, the improved “”one-pot”” preparation method results in a significantly higher yield. Subsequently, two different macromol. CTA segments (PVP-CTA-PVP and PDMAEMA-CTA-PDMAEMA) were prepared by RAFT polymerization, followed by the synthesis of the block polymer PDMAEMA-b-PVP-CTA-PVP-b-PDMAEMA. Through FITR, NMR, GPC and DLS anal. of the block polymer, it was observed that the isotacticity gradually became dominant as the d.p. increased. Further, using NMR spectroscopy to study the effect of pH on the block polymer, the ionization degree of the synthesized polymer in the tumor tissue environment was observed to range between 86.32% to 99.50%, which proved that the synthesized polymers exhibit significant prospects in the medical application.

《Imidazolium-Functionalized Ionic Hypercrosslinked Porous Polymers for Efficient Synthesis of Cyclic Carbonates from Simulated Flue Gas》 was written by Zhang, Wenli; Ma, Fangpei; Ma, Long; Zhou, Yu; Wang, Jun. SDS of cas: 623-24-5 And the article was included in ChemSusChem in 2020. The article conveys some information:

The rapid growth of CO2 emissions, especially from power plants, has led to the urgent need to directly capture and fix CO2 in the flue gas after simple purification rather than energy-intensive gas separation Herein, imidazolium-functionalized ionic hypercrosslinked porous polymers (HCPs) bearing adjustable surface groups were straightforwardly synthesized through co-hypercrosslinking of benzylimidazole salts and crosslinker through Friedel-Crafts alkylation. Abundant microporosity and relatively high ionic moieties were obtainable in the ethyl-group-tethered ionic HCP, giving a remarkably selective CO2 capture performance with a CO2 uptake of 3.05 mmol g-1 and an ideal adsorbed solution theory (IAST) CO2/N2 selectivity as high as 363 (273 K, 1 bar). This ionic polymer demonstrated high efficiency in the synthesis of cyclic carbonates from the coupling of various epoxides with the simulated flue gas (15% CO2 and 85% N2), giving high yields, large turnover numbers (up to 4800), and stable reusability under additive- and solvent-free conditions.

The title of the article was 《Phosphine Oxide Porous Organic Polymers Incorporating Cobalt(II) Ions: Synthesis, Characterization, and Investigation of H2 Production》.COA of Formula: C8H8Br2 The author mentioned the following in the article:

Suitably functionalized porous matrixes represent versatile platforms to support well-dispersed catalytic centers. In the present study, porous organic polymers (POPs) containing phosphine oxide groups were fabricated to bind transition metals and to be investigated for potential electrocatalytic applications. Crosslinking of mono- and di-phosphine monomers with multiple Ph substituents was subject to the Friedel-Crafts (F-C) reaction and the oxidation process, which generated phosphine oxide porous polymers with pore capacity up to 0.92 cm3/g and a surface area of about 990 m2/g. The formation of the R3P·BH3 borohydride adduct during synthesis allows to extend the library of phosphine-based monomeric entities when using FeCl3. The porous polymers were loaded with 0.8-4.2 weight/weight % of cobalt(II) and behaved as hydrogen evolution reaction (HER) catalysts with a Faradaic efficiency of up to 95% (5.81 x 10-5 mol H2 per 11.76 C) and a stable c.d. during repeated controlled potential experiments (CPE), even though with high overpotentials (0.53-0.68 V to reach a c.d. of 1 mA·cm-2). These studies open the way to the effectiveness of tailored phosphine oxide POPs produced through an inexpensive and ecofriendly iron-based catalyst and for the insertion of transition metals in a porous architecture, enabling electrochem. driven activation of small mols.

《Enhanced efficacy of gefitinib in drug-sensitive and drug-resistant cancer cell lines after arming with a singlet oxygen releasing moiety》 was written by Huang, Kunshan; Huo, Beibei; Li, Dongyao; Xue, Jinping; Chen, Juanjuan. Reference of 1,4-Bis(bromomethyl)benzene And the article was included in ChemMedChem in 2020. The article conveys some information:

Attractive results have been achieved with small-mol. target-based drugs in the anticancer field; however, enhancing their treatment effect and solving the problem of drug resistance remain key concerns worldwide. Inspired by the specific affinity of gefitinib for tumor cells and the strong oxidation capacity of singlet oxygen, we combined a chem. generated singlet oxygen moiety with the small-mol. targeted drug gefitinib to improve its anticancer effect. We designed and synthesized a novel compound (Y5-1), in which a small-mol. targeted therapy agent (gefitinib) and a singlet oxygen (provided by an in vitro photodynamic reaction) thermally controlled releasing moiety are covalently conjugated. We demonstrated that the introduction of the singlet oxygen thermally controlled releasing moiety enhanced the anticancer activities of gefitinib. The results of this study are expected to provide a novel strategy to enhance the effect of chemotherapy drugs on drug-resistant cell lines.

In 2022,Eftaiha, Ala’a F.; Qaroush, Abdussalam K.; Abo-shunnar, Ahmad S.; Hammad, Suhad B.; Assaf, Khaleel I.; Al-Qaisi, Feda’a M.; Paige, Matthew F. published an article in Langmuir. The title of the article was 《Interfacial Behavior of Modified Nicotinic Acid as Conventional/Gemini Surfactants》.Category: bromides-buliding-blocks The author mentioned the following in the article:

We report the synthesis and monolayer properties of conventional and gemini surfactants composed of nicotinic acid-based head groups with an emphasis on assessing how chem. structures affect the behavior of monolayers. A combination of Brewster angle microscopy and at. force microscopy showed that pure hexadecyl nicotinate formed rippled strands in monolayers, and the gemini correspondents with either flexible or rigid organic linkers resulted in lobed-compact domains, which provides a simple method for patterning air-water and solid-air interfaces. The structural differences between conventional and gemini nicotinic acid-based surfactants could be explained by the interplay between line tension (that favors the formation of circular domains), balanced by dipole-dipole repulsion interaction between headgroups, which promotes extended domains. Miscibility and morphol. studies of the modified nicotinic acid surfactants with palmitic acid demonstrated that the properties of mixed films can be controlled by the structure of the former. Excess Gibbs free energies of mixing indicated that the mixed films were less stable than the pure monolayers, and the pos. deviations from ideality were the largest in the case of gemini surfactants.1,4-Bis(bromomethyl)benzene(cas: 623-24-5Category: bromides-buliding-blocks) was used in this study.

The synthesis of new triphenylphosphonium-capped cucurbit[7]uril (CB[7])- and cucurbit[8]uril (CB[8])-based [2]rotaxanes was achieved by a simultaneous threading-capping strategy. While the use of CB[7] produced the designed [2]rotaxane, attempts to obtain the CB[8] analog were unsuccessful due to the unexpected strong interaction found between the host and the phosphonium caps leading to pseudo-heteroternary host-guest complexes.

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.
