Mezzetta, Andrea; Guglielmero, Luca; Mero, Angelica; Tofani, Giorgio; D’Andrea, Felicia; Pomelli, Christian Silvio; Guazzelli, Lorenzo published their research in Molecules in 2021. The article was titled 《Expanding the Chemical Space of Benzimidazole Dicationic Ionic Liquids》.Recommanded Product: 629-03-8 The article contains the following contents:

Benzimidazole dicationic ionic liquids (BDILs) have not yet been widely explored in spite of their potential. Therefore, two structurally related families of BDILs, paired with either bromide or bistriflimide anions and bearing alkyl spacers ranging from C3 to C6, have been prepared Their thermal properties have been studied by thermogravimetric anal. (TGA) and differential scanning calorimetry (DSC), while their elec. properties have been assessed by cyclic voltammetry (CV). TG anal. confirmed the higher stability of the bistriflimide BDILs over the bromide BDILs, with minor variation within the two families. Conversely, DSC and CV allowed for ascertaining the role played by the spacer length. In particular, the thermal behavior changed dramatically among the members of the bistriflimide family, and all three possible thermal behavior types of ILs were observed Furthermore, cyclic voltammetry showed different electrochem. window (C3(C1BenzIm)2/2Tf2N < C4(C1BenzIm)2/2Tf2N, C5(C1BenzIm)2/2Tf2N < C6(C1BenzIm)2/2Tf2N) as well as a reduction peak potential, shape, and intensity as a function of the spacer length. The results obtained highlight the benefit of accessing a more structurally diverse pool of compounds offered by dicationic ILs when compared to the parent monocationic ILs. In particular, gains are to be found in the ease of fine-tuning their properties, which translates in facilitating further investigations toward BDILs as designer solvents and catalysts. The experimental process involved the reaction of 1,6-Dibromohexane(cas: 629-03-8Recommanded Product: 629-03-8)

Wang, Weiwei; Zhang, Yaqin; Yang, Zifeng; Zhang, Zhencai; Fang, Wenjuan; Niu, Donghui; He, Hongyan; Xu, Fei published an article in 2021. The article was titled 《Efficient synthesis of isosorbide-based polycarbonate with scalable dicationic ionic liquid catalysts by balancing the reactivity of the endo-OH and exo-OH》, and you may find the article in Green Chemistry.Related Products of 629-03-8 The information in the text is summarized as follows:

In this study, a series of high-activity imidazole-based dicationic ionic liquids (DILs) were designed and prepared as efficient catalysts for balancing the reactivity between the endo-hydroxyl group (endo-OH) and the exo-hydroxyl group (exo-OH) of isosorbide (ISO) to synthesize high mol. weight poly(isosorbide carbonate) (PIC). Meanwhile, the thermal performance of PIC was precisely optimized by regulating the chain configuration. When the trace amounts (4.5 x 10-5 based on the ISO molar amount) of bis-(3-methyl-1-imidazole)-ethylene dibromide ([C2(Min)2][Br]2) were used, the weight average mol. weight (Mw) of PIC reached 98 700 g mol-1. It could be concluded from the results of the experiment and the stimulation that the high catalytic activity of DILs was attributed to the strong electrostatic interaction between the cation and the substrate and the effective balance of the reactivity of the endo-OH and the exo-OH. Furthermore, we found that the reduction of hydroxyl groups in the terminal groups and the increase of endo-endo (a1) structure in the repeating unit improved the thermal properties of PIC. Finally, 1H NMR, Fourier IR spectroscopy, and d. functional theory (DFT) calculations were used to verify the reaction process through anion and cation multi-site synergistic effect and a possible electrophilic-nucleophilic reaction mechanism was successfully obtained.1,6-Dibromohexane(cas: 629-03-8Related Products of 629-03-8) was used in this study.

《Synthesis of a novel fluorescent berberine derivative convenient for its subcellular localization study》 was published in Bioorganic Chemistry in 2020. These research results belong to Jin, Meng; Ji, Xiuna; Stoika, Rostyslav; Liu, Kechun; Wang, Lizhen; Song, Yang. Synthetic Route of C6H12Br2 The article mentions the following:

Berberine is a naturally occurred isoquinoline alkaloid that shows great potential for developing anticancer drugs. However, the problem stays of poor understanding of the mechanisms of anticancer action of berberine. It depends on evaluation of berberine’s pharmacokinetics, namely monitoring of its uptake and distribution in cells, tissues and organs. In order to address these problems, we have designed and synthesized a novel berberine derivative BBR-BODIPY bearing a fluorescent tag that allows screening its interaction with the targeted cells. It was shown that the synthesized fluorescent derivative could penetrate into human breast carcinoma MCF7 cells, and then induced apoptosis detected by the Western Blot anal. as changed expression of apoptosis-related proteins, including Bax, Bcl2, and Cyto C released from mitochondria, Cleaved Caspase 9, Cleaved PARP, Pro-Caspase 3, and Cleaved Caspase 3. The results of MitoTracker anal. followed by the confocal microscopy of sub-cellular localization of BBR-BODIPY in the MCF7 cells demonstrated excellent cell-penetrating ability of this compound even at low concentrations, and mitochondria was the main site of its accumulation. Together with the results of Western Blot anal., these data indicated that the mitochondria pathway might be involved in berberine-induced apoptosis. In the experiment, the researchers used many compounds, for example, 1,6-Dibromohexane(cas: 629-03-8Synthetic Route of C6H12Br2)

《Kinetic study of the metal-dipeptide complex with ninhydrin facilitated by gemini (m-s-m) surfactant micelles》 was written by Azum, Naved; Kumar, Dileep. SDS of cas: 629-03-8 And the article was included in Scientific Reports in 2020. The article conveys some information:

The three Gemini (m-s-m; m (head group) = 16 and s (spacer) = 4, 5, 6) surfactants have been synthesized and their impact on reaction of zinc(II)-glycylleucine complex ([Zn(II)-Gly-Leu]+) and ninhydrin were studied at temperature (343 K) and pH (5.0) using spectroscopic method. Influence of several factors, viz., [Zn(II)-Gly-Leu]+, [ninhydrin], temperature and pH were also carried out on title reaction in geminis. Rates of reaction are the first-order path in concentration of [Zn(II)-Gly-Leu]+ complex and fractional order path in concentration of ninhydrin. The catalysis of gemini 16-s-16 surfactant micelles was investigated below and above their critical micelle concentration (cmc) value and detailed elaboration were provided in the text. In the present case, rate constants, kψ, increased on increasing geminis ([gemini] are below their cmc, region I) and stayed nearly constant (region II). The shape of (region I and II) surfactants ([gemini] = 0 to 400 × 10-5 mol dm-3) are similar to a cetyltrimethylammonium bromide, CTAB (single hydrophilic head group and hydrophobic part). Later, a sharp increment in rate was observed with higher [gemini] (region III, (Fig. 5)). The study was catalyzed and accelerated quite enough by geminis (at concentrations below their cmc) compared to aqueous An appropriate mechanism has been proposed for accounting for the distribution of reactants between aqueous and micellar pseudo phases. Resulting kinetic data were used to determine the binding constants of micelle-substrate (KB) and micelle-ninhydrin (KNin). The results came from multiple reactions, including the reaction of 1,6-Dibromohexane(cas: 629-03-8SDS of cas: 629-03-8)

And the article was published in Polymer Chemistry in 2019. HPLC of Formula: 629-03-8 The author mentioned the following in the article:

A series of luminescent side chain polymers containing a D-π-A structure and different flexible spacer lengths, namely, poly[(Z)-ω-(4-(1-cyano-2-(4-cyanophenyl)vinyl)phenoxy)alkyl methacrylate]s (PMmPVPCN, m = 2, 4, 6, 8), were successfully prepared With the combination of aggregation-induced emission enhancement (AIEE) luminogens and mesogens, the resultant polymers are expected to possess both liquid crystal characteristics and AIEE characteristics. The phase structure of PMmPVPCN was explored by differential scanning calorimetry (DSC), polarized optical microscopy (POM), and one-dimensional wide-angle X-ray diffraction (1D WAXD). Photophys. properties of PMmPVPCN were studied by UV spectra and fluorescence spectra. Test results suggested that the phase structure of PMmPVPCN transformed from the amorphous phase (PMmPVPCN, m = 2, 4) to the nematic phase (PMmPVPCN, m = 6, 8) with the increase of polymer spacer length. All the synthetic monomers and polymers exhibited AIEE properties and the luminescence behavior of PMmPVPCN was associated with their chem. structure. The solid fluorescence quantum yields of PMmPVPCN increased from 22.4% to 42.7% with increasing spacer length. The polymer films also showed reversible fluorescence photo-responsive properties. The emission color and the emission intensity of polymer films changed when exposed to a 365 nm UV lamp. The change process was reversible and they could turn back to their original state when irradiated with a 254 nm UV lamp or heated at higher temperature In the experiment, the researchers used 1,6-Dibromohexane(cas: 629-03-8HPLC of Formula: 629-03-8)

Yu, Zhen-Qiang; Li, Xiaodong; Wan, Wei; Li, Xin-Shun; Fu, Kuo; Wu, Yue; Li, Alexander D. Q. published their research in Chemical Science in 2021. The article was titled 《Cooperatively assembled liquid crystals enable temperature-controlled Forster resonance energy transfer》.Category: bromides-buliding-blocks The article contains the following contents:

Balancing the rigidity of a π-conjugated structure for strong emission and the flexibility of liquid crystals for self-assembly is the key to realizing highly emissive liquid crystals (HELCs). Here we show that (1) integrating organization-induced emission into dual mol. cooperatively-assembled liquid crystals, (2) amplifying mesogens, and (3) elongating the spacer linking the emitter and the mesogen create advanced materials with desired thermal-optical properties. Impressively, assembling the fluorescent acceptor Nile red into its host donor designed according to the aforementioned strategies results in a temperature-controlled Forster resonance energy transfer (FRET) system. Indeed, FRET exhibits strong S-curve dependence as temperature sweeps through the liquid crystal phase transformation. Such thermochromic materials, suitable for dynamic thermo-optical sensing and modulation, are anticipated to unlock new and smart approaches for controlling and directing light in stimuli-responsive devices.

The article was titled 《A novel AIE chemosensor based on quinoline functionalized Pillar[5]arene for highly selective and sensitive sequential detection of toxic Hg2+ and CN-》. The information in the text is summarized as follows:

Aggregation-induced emission (AIE) is widely used for fluorescence on-off-on detection ions and mol. Herein, the authors report a novel AIE chemosensor through self-assembly of quinoline functionalized pillar[5]arene (SPQ5). The SPQ5 can bind with Hg2+ tightly through coordinating reaction. By introducing Hg2+ into AIE-based chemosensor, metal-coordinated chemosensor (SPQ5-Hg2+) was obtained, the SPQ5-Hg2+ could high selectively and sensitively detection of CN- by competitive coordinating interactions. The LODs of SPQ5 for Hg2+ and CN- are 2.53 × 10-8 M and 7.71 × 10-8 M, resp. Hg2+ test kit was prepared by loading the SPQ5 chemosensor on a silica gel plate, which could more convenient and efficiency detection Hg2+ and CN-. The chemosensor SPQ5 could instant sense the Hg2+ and CN- by the changing of fluorescence color and fluorescence intensity. Notably, the fluorescence intensity changes of SPQ5 upon the addition of Hg2+ and CN- were used as an IMP logic gate at the mol. level, using Hg2+ and CN- as chem. inputs and the fluorescence intensity signal as the output. However, the test kit by loading SPQ5 on a silica gel plate was prepared for convenient detection of Hg2+.

In 2019,Electrochimica Acta included an article by Wu, Hong Yue; Yang, Qian; Gao, Xue Lang; Zhu, Zhao Yu; Sun, Qi Hui; Zhang, Qiu Gen; Zhu, Ai Mei; Liu, Qing Lin. Quality Control of 1,6-Dibromohexane. The article was titled 《Novel crosslinked aliphatic anion exchange membranes with pendant pentafluorophenyl groups》. The information in the text is summarized as follows:

To enhance the performance of anion exchange membranes (AEMs) by constructing effective ion channels, the authors synthesized novel aliphatic polymers with pentafluorophenyl pendent groups via superacid catalyzed polyhydroxyalkylation and quaternization by grafting multi-cation crosslinker through the Menshutkin reaction. The procedure adopted in this study for preparing the AEMs circumvented the use of precious metal catalysts and made it easy to control the reaction conditions. Compared with the traditional aliphatic AEMs, the AEMs prepared by the new strategy exhibited well-developed microphase-separated structures by increasing the hydrophilic/hydrophobic difference between the polymer backbones and the side chains. Also, the multi-cation crosslinker not only provides ion exchange groups but also constrains the swelling of the AEMs. As the authors expected, the well-defined ion channels were validated by TEM and small angle x-ray scattering (SAXS). The CPFBP-TQA-100 membrane shows a highest ion conductivity of 76.85 mS cm-1 and a swelling ratio of only 24.8% at 80°. A maximum power d. of 116.7 mW cm-2 is achieved by a single cell using the CPFBP-TQA-100 membrane at a c.d. of 300 mA cm-2 at 80°. Besides, all the AEMs display excellent thermal stability and reasonable alk. stability.
