The author of the article were Zhang, Jun; Shang, Chengyuan; Yu, Zhuoer; Wang, Linxiao; Tang, Junkun; Huang, Farong. The article conveys some information:

Dynamic covalent materials are a class of polymer that could be stress-relaxation, reprocessable, and self-healing due to dynamic crosslinks in network. Dynamic crosslinks play an important role in the typical characteristic of self-healing polymers. It is meaningful to understand the effect of crosslinking degree on the properties of poly(1,2,3-triazolium) (PTAM). In this article, the dynamic covalent network of PTAM adhesive was used to study the effect of crosslinking degree. PTAM adhesive with different crosslinking degrees were obtained by changing the amount of crosslinker. Adhesion property can rise then fall down with the increase of crosslinking degree and the best lap-shear strength is >20 MPa. Creep resistance and solvent resistance can be enhanced with the increase of crosslinking degree. Self-healing studies showed that crosslinking degree can enhance the ability of self-healing, but too high crosslinking degree raises the temperature of self-healing and causes side reaction which reduces the self-healing efficiency. These results provide some insights for the influence of the crosslinking degree on the self-healing and the structural design of dynamic covalent materials.

《Universal Antibacterial Surfaces Fabricated from Quaternary Ammonium Salt-Based PNIPAM Microgels》 was published in ACS Applied Materials & Interfaces in 2020. These research results belong to Zhao, Ziqing; Ma, Xiaoliang; Chen, Rui; Xue, Hui; Lei, Jiehua; Du, Hui; Zhang, Zexin; Chen, Hong. Name: 1,6-Dibromohexane The article mentions the following:

Because of the excellent film-forming ability of poly(N-isopropylacrylamide) (PNIPAM) microgel and high-efficient bactericidal property of quaternary ammonium salt (QAS), QAS-based PNIPAM (QAS-PNIPAM) microgels are synthesized and employed to modify the surface of a range of commonly used materials including metal, plastic, and elastomer. Bacterial culture is carried out on such QAS-PNIPAM microgel-modified surfaces to examine the viability of the attached bacteria. It is found that the bactericidal efficiency is nearly 100% on the modified surfaces of all the studied materials. We attribute the high-efficient bactericidal performance of QAS-PNIPAM microgel film to the QAS component rather than the topog. of the microgel film itself. In addition, the microgel film is robust and shows great integrity even after culture of the bacteria and repeated rinses, and the cell experiment demonstrates that this microgel film is cyto-compatible. Therefore, such a simple, versatile method of preparing antibacterial films paves the way for future bactericidal applications.

《Control over the Aspect Ratio of Supramolecular Nanosheets by Molecular Design》 was written by Sasaki, Norihiko; Yuan, Jennifer; Fukui, Tomoya; Takeuchi, Masayuki; Sugiyasu, Kazunori. Formula: C6H12Br2 And the article was included in Chemistry – A European Journal in 2020. The article conveys some information:

Recent developments in kinetically controlled supramol. polymerization permit control of the size (i.e., length and area) of self-assembled nanostructures. However, control of mol. self-assembly at a level comparable with organic synthetic chem. and the achievement of structural complexity at a hierarchy larger than the mol. level remain challenging. This study focuses on controlling the aspect ratio of supramol. nanosheets. A systematic understanding of the relationship between the monomer structure and the self-assembly energy landscape has derived a new monomer capable of forming supramol. nanosheets. With this monomer in hand, the aspect ratio of a supramol. nanosheet is demonstrated that it can be controlled by modulating intermol. interactions in two dimensions. The results came from multiple reactions, including the reaction of 1,6-Dibromohexane(cas: 629-03-8Formula: C6H12Br2)

The article was titled 《Strong-Induced CPL Emission Promoted from Achiral Conjugated Polymer-Containing Emissive Nematic Liquid Crystals (P-N*-LCs)》.SDS of cas: 629-03-8 The article contains the following contents:

With the rapid development on 3D printing technol., more and more works have been devoted to 3D display. 3D display will really come true by using circularly polarized luminescence (CPL)-active materials with both high quantum yield and dissymmetry factor (gem) in organic light-emitting diode OLED or liquid crystals (LCs). But so far most of these CPL materials cannot meet the real application requirement because of the low gem values in the range of 10-5-10-2. In this paper, ternary chiral emissive LCs (P-N*-LCs) is designed by doping chiral binaphthyl-based enantiomers as chiral dopant I (Guest 1) and achiral conjugated polymer as induced CPL emitter II (Guest 2) into nematic liquid crystal (N-LCs) Host 5CB. Both Guest 1 and Guest 2 show excellent compatibility with Host 5CB. The obtained ternary P-N*-LCs can emit strong-induced CPL signal with gem up to 1.12 and ΦFL up to 66.1%. This work first develops a new strategy for the smart design of excellent CPL materials from versatile achiral conjugation fluorescence polymers.

Synthetic Route of C6H12Br2In 2022 ,《Thermosensitive Microgels Containing AIEgens: Enhanced Luminescence and Distinctive Photochromism for Dynamic Anticounterfeiting》 was published in ACS Applied Materials & Interfaces. The article was written by Dong, Shunni; Zang, Qiguang; Ma, Zhao-Yu; Tang, Meiqi; Xu, Zhi-Kang; Nie, Jingjing; Du, Binyang; Sun, Jing Zhi; Tang, Ben Zhong. The article contains the following contents:

The proposal of the aggregation-induced emission (AIE) effect shines a light on the practical application of luminescent materials. The AIE-active luminescence microgels (TPEC MGs) with photo-induced color-changing behavior were developed by integrating pos. charged AIE luminogens (AIEgens) into the anionic network of microgels, where AIEgens of TPEC were obtained from the quaternization reaction between tetra-(4-pyridylphenyl)ethylene (TPE-4Py) and 7-(6-bromohexyloxy)-coumarin. The aqueous suspensions of TPEC MGs exhibit a significant AIE effect following the enhancement of quantum yield. In addition, further increase in fluorescence intensity and blueshift occur at elevated temperatures due to the collapse of microgels. The distinctive photochromic behavior of TPEC MGs was observed, which presents as the transition from orange-yellow to blue-green color under UV irradiation, which is different from TPEC in good organic solvents. The phenomenon of color changing can be ascribed to the competition between photodimerization of the coumarin part and photocyclization of TPE-4Py in TPEC. The photochromic TPEC MG aqueous suspensions can be conducted as aqueous microgel inks for information display, encryption, and dynamic anticounterfeiting.

The article was titled 《Benzofuran-isatin-imine hybrids tethered via different length alkyl linkers: Design, synthesis and in vitro evaluation of anti-tubercular and anti-bacterial activities as well as cytotoxicity》. The information in the text is summarized as follows:

The design and synthesis of twenty-two novel benzofuran-isatin-imine hybrids I [R1 = H, F, OCH3; X = (CH2)n; Y = NOCH3, NOC2H5, NNHC(S)NH2, NOH; R3 = H, OCH3, F; n = 1, 2, 3, 4] tethered through propylene, butylene, pentylene and hexylene, and for the evaluation of their in vitro anti-tubercular and anti-bacterial activities as well as cytotoxicity were reported. All benzofuran-isatin-imine hybrids exhibited considerable in vitro anti-TB (MIC: <0.016-0.218 μg/mL and 0.062-14.15 μg/mL against drug-sensitive and MDR MTB, resp.) and anti-bacterial (MIC: 0.25-64 μg/mL and 0.06-16 μg/mL against Gram-pos. and Gram-neg. strains, resp.) activities. All of them also showed acceptable cytotoxicity towards VERO (CC50: 8-128 μg/mL). The most active hybrid I (R1 = H; X = CH2CH2; Y = NOCH3; R3 = OCH3) (MIC: <0.016, 0.062 and 0.16 μg/mL, resp.) was >4.8 and >48 folds more potent than the first line anti-TB agents RIF and INH against both drug-sensitive MTB H37Rv and MDR-TB isolates, resp. Moreover, hybrid I (R1 = H; X = CH2CH2; Y = NOCH3; R3 = OCH3) also demonstrated promising anti-bacterial activities with MIC values of ≤1 μg/mL against the majority of the tested Gram-neg. and Gram-pos. pathogens, which was comparable to vancomycin (MIC: 0.5-4 μg/mL) and CPFX (MIC: 0.125-8 μg/mL) against Gram-pos. bacteria, but slightly less potent than CPFX (MIC: ≤0.03-0.5 μg/mL) against Gram-neg. bacteria. The results indicated that benzofuran-isatin-imine hybrids could act as candidates for the development of anti-TB and anti-bacterial agents.

Yang, Q.; Sun, L. X.; Gao, W. T.; Zhu, Z. Y.; Gao, X.; Zhang, Q. G.; Zhu, A. M.; Liu, Q. L. published their research in Journal of Colloid and Interface Science in 2021. The article was titled 《Crown ether-based anion exchange membranes with highly efficient dual ion conducting pathways》.Formula: C6H12Br2 The article contains the following contents:

Anion exchange membranes (AEMs) are a crucial constituent for alk. fuel cells. As the core component of fuel cells, the low performance AEMs restrict the development and application of the fuel cells. Herein, the trade-off between the OH- conductivity and dimensional stability was solved by constructing AEMs with adequate OH- conductivity and satisfactory alkali resistance using Troger′s base (TB) poly (crown ether)s (PCEs) as the main chain, the embedded quaternary ammonium (QA) and Na+-functionalized crown ether units as the cationic group. Crown ether is an electron donator, and can capture Na+ to form Na+-functionalized crown ether units to conveniently transfer OH- and significantly promote the alk. stability of the AEMs. The influence of the Na+-functionalized crown ether units on the performance of AEMs was studied in detail. The PCEs based AEMs show an obvious hydrophobic-hydrophilic microphase separation These features make them ideal platforms for the OH- conduction applications. As expected, the as-prepared PCEs-QA-100% (100% is the degree of crosslinking) AEM with an ionic exchange capacity (IEC) of 2.07 meq g-1 has a high OH- conductivity of 159 mS cm-1 at 80 °C. Furthermore, the membrane electrode assemblies fabricated using the PCEs-QA-100% AEM possess a maximum power d. of 291 mW cm-2 under the c.d. of 500 mA cm-2. In addition to this study using 1,6-Dibromohexane, there are many other studies that have used 1,6-Dibromohexane(cas: 629-03-8Formula: C6H12Br2) was used in this study.
