Compound: 11-Bromoundecanoic acid, is researched, Molecular C11H21BrO2, CAS is 2834-05-1, about Activation of a Copper Biscarbene Mechano-Catalyst Using Single-Molecule Force Spectroscopy Supported by Quantum Chemical Calculations.

Single-mol. force spectroscopy allows study of the effect of mech. force on individual bonds. By determining the forces necessary to sufficiently activate bonds to trigger dissociation, it is possible to predict the behavior of mechanophores. The force necessary to activate a Cu biscarbene mechano-catalyst intended for self-healing materials was measured. By using a safety line bypassing the mechanophore, it was possible to pinpoint the dissociation of the studied bond and determine rupture forces to range from 1.6 to 2.6 nN at room temperature in DMSO. The average length-increase upon rupture of the Cu-C bond, due to the stretching of the safety line, agrees with quantum chem. calculations, but the values exhibit an unusual scattering. This scattering was assigned to the conformational flexibility of the mechanophore, which includes formation of a threaded structure and recoiling of the safety line.

The three-dimensional configuration of the ester heterocycle is basically the same as that of the carbocycle. Compound: 11-Bromoundecanoic acid(SMILESS: O=C(O)CCCCCCCCCCBr,cas:2834-05-1) is researched.Recommanded Product: Nickel(II) bromide ethylene glycol dimethyl ether complex. The article 《Control of Director Fields in Phospholipid-Coated Liquid Crystal Droplets》 in relation to this compound, is published in Langmuir. Let’s take a look at the latest research on this compound (cas:2834-05-1).

In liquid crystal (LC) droplets, small changes in surface anchoring energy can produce large changes in the director field which result in readily detectable optical effects. This makes them attractive for use as biosensors. Coating LC droplets with a phospholipid monolayer provides a bridge between the hydrophobic world of LCs and the water-based world of biol. and makes it possible to incorporate naturally occurring biosensor systems. However, phospholipids promote strong perpendicular (homeotropic) anchoring that can inhibit switching of the director field. We show that the tendency for phospholipid layers to promote perpendicular anchoring can be suppressed by using synthetic phospholipids in which the acyl chains are terminated with bulky tert-Bu or ferrocenyl groups; the larger these end-group(s), the less likely the system is to be perpendicular/radial. Addnl., the droplet director field is found to be dependent on the nature of the LC, particularly its intrinsic surface properties, but not (apparently) on the sign of the dielec. anisotropy, the proximity to the melting/isotropic phase transition, the surface tension (in air), or the values of the Frank elastic constants

Through the article, more information about this compound (cas:2834-05-1) is conveyed.

A new approach to the synthesis of sulfonyl chloride initiators with the calixarene core for the cationic polymerization of 2-oxazolines is developed. The kinetics of 2-ethyl-2-oxazoline polymerization with the synthesized octafunctional initiator at 100°C in sulfolane is studied. It is shown that the decelerated initiation of polymerization is observed in the system and the rate constant of chain propagation is kp = 1.20 x 10-3 L/(mol s). Using the cationic ring-opening polymerization of 2-alkyl-2-oxazolines initiated by calix[8]arene functionalized by sulfonyl chloride groups in the lower rim, star-shaped thermosensitive polymers are synthesized, and the mol. weight characteristics of the polymers are investigated. The critical micelle concentration of star-shaped poly(2-isopropyl-2-oxazoline) is determined (CCMC = 6.25 x 10-5 g/mL), and the solubilizability of the synthesized polymers is investigated using hydrophobic dye curcumin as an example.

Electric Literature of C11H21BrO2. The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. Compound: 11-Bromoundecanoic acid, is researched, Molecular C11H21BrO2, CAS is 2834-05-1, about Modification of polyhydroxyalkanoates: Evaluation of the effectiveness of novel copper(II) catalysts in click chemistry. Author is Nkrumah-Agyeefi, Samuel; Pella, Bruce J.; Singh, Nirupama; Mukherjee, Anusree; Scholz, Carmen.

Copper(I) catalyzed azide-alkyne cycloadditions, click reactions, are an established synthetic tool to derivatize polymers. Only a few catalytic systems have been explored toward the derivatization of functionalized poly(3-hydroxyalkanoate)s, PHAs, using click reactions. Here, the performances of three Cu(II)-catalysts supported by tetradentate polypyridyl ligands, [Cu(L1)ClO4]ClO4, [Cu(L2)ClO4]ClO4 and [Cu(L3)ClO4]ClO4, were examined in click reactions on functionalized PHAs carrying either terminal azido or alkyne groups in the side chain and the results were compared to the traditional CuSO4·5H2O/Na ascorbate and the organo-soluble Cu(I) bromotris(triphenylphosphine)copper(I), CuBr(PPh3)3 catalysts. It was determined that the effectiveness of the catalytic systems depended on the mol. architecture of the polymer and the nature of the small mol. reactants to be clicked onto the PHA. Click reactions on PHAs with terminal azido groups were catalyzed with Cu(II)-catalysts, but not with CuBr(PPh3)3. For alkyne-containing polymers CuBr(PPH3)3 effected 65% conversion in contrast to Cu(II) catalysts that were ineffective. While no strong trend was found, differences in the effectiveness were related to dissimilarities in the accessibility of the alkyne moiety for the reactive Cu(I) species. Propargyl benzoate was most effectively clicked onto a azido PHA (100% conversion) when catalyzed by CuSO4·5H2O/Na ascorbate, however the click reaction with a similar reactant, propargyl acetate, was more effectively catalyzed by a Cu(II)-catalyst supported by a tetradentate polypyridyl ligand (44% conversion).

Robust synthesis of large-scale self-assembled nanostructures with long-range organization and a prominent response to external stimuli is critical to their application in functional plasmonics. Here, the 1st example of a material made of liquid crystalline nanoparticles which exhibits UV-light responsive surface plasmon resonance in a condensed state is presented. To obtain the material, metal cores are grafted with 2 types of organic ligands. A promesogenic derivative softens the system and induces rich liquid crystal phase polymorphism. Second, an azobenzene derivative endows nanoparticles with photoresponsive properties. Nanoparticles covered with a mixture of these ligands assemble into long-range ordered structures which exhibit a novel dual-responsivity. The structure and plasmonic properties of the assemblies can be controlled by a change in temperature as well as by UV-light irradiation These results present an efficient way to obtain bulk quantities of self-assembled nanostructured materials with stability that is unattainable by alternative methods such as matrix-assisted or DNA-mediated organization.

A simple nanostructured, photoresponsive film made from a coumarin-modified tetrafunctional monomer, which is both photodegradable and photoreproducible, was prepared using a simple spin-coating process and UV irradiation The film produced from this system self-healed scratches using only UV light, with no need for catalyst, heat, or other stimuli. The photoreversible mechanism was investigated, and a range of techniques were used to characterize the resultant photoproducts after the polymerization and depolymerization processes. IR spectroscopy was used to determine the optimal energy for a complete reversible polymerization reaction, and the mechanism was further confirmed by UV-vis spectroscopy which was able to monitor key structural changes. GPC anal. was used to track the mol. weight changes after the depolymerization reaction, which showed that the polymer was able to be converted back to monomers and oligomers, demonstrating the highly reversible polymerization and suggesting a potential for recyclability. Microhardness measurements of neat and irradiated samples were also used to determine the changes in mech. properties before and after cleavage of the polymer network, and following the recovery of its structure, the latter showed a recovery of up to 91% of its mech. properties.

The precursor salt 2 and its derivative 3 were successfully synthesized in excellent yields and characterized using different spectroscopic techniques. For the first time, a detailed study on the corrosion inhibition behavior of corrosion inhibitors 2 and 3 for mild steel in 1 M HCl was carried out using electrochem. measurements and comprehensive computational anal. Both the studied inhibitors showed excellent aqueous solubility The high inhibition efficiency of 91% and 93% at a concentration of 200 mg L-1 was obtained for corrosion inhibitors 2 and 3, resp. The adsorption of the corrosion inhibitors exhibited the Langmuir isotherm with a mixture of phys. and chem. modes of adsorption. The impedance studies showed a rise in the polarization resistance with increasing concentration of the inhibitors. Polarization measurements demonstrated that the inhibitors displayed a mixed-mode of inhibition with primarily cathodic nature. Surface anal. studies supported the inhibitor adsorption and a protective film formation on the carbon steel surface, which improved the surface smoothness of the steel surface. The DFT based quantum chem. calculations supported the exptl. obtained results and showed that the inhibitor 3 displays superior inhibition in comparison to the inhibitor 2. The Monte Carlo simulations revealed higher adsorption energy for the inhibitor 3 compared to 2.

The present work aims to develop and evaluate a radioactive technetium-99m (99mTc) labeled gold nanoparticle (NP) preparation modified with folic acid, so as to diagnose folate receptor pos. cancers viz. ovarian, breast, etc.11-Bromoundecanoic acid (UA) was synthetically modified both with folic acid and Hydrazinonicotinic acid (HYNIC) chelate at the carboxylic acid end and subsequently converted to thiol functionality at the bromo terminal to yield folic acid-UA-SH and HYNIC-UA-SH ligands resp. Gold NPs modified with folic acid and HYNIC chelator were obtained on direct addition of folic acid-UA-SH and HYNIC-UA-SH to chloroauric acid in polysorbate 80 solution under reducing conditions. Inhibition of [3H]folic acid with functionalized gold nanoparticle revealed affinity towards FR pos. KB cell lines with an IC50 9 μM. Biodistribution studies of 99mTc-labeled gold NP preparation in SCID mice bearing KB tumor showed an uptake of 1.39 ± 0.18%ID/g in tumor and 5.48 ± 0.72%ID/g in kidneys at 3 h post-injection. In vivo distribution in folic acid pre-treated animals could not establish the specificity towards folate receptors. Biol. evaluation of functionalized gold NP showed affinity towards FR pos. cancer cell lines. 99mTc-labeled NP exhibited target uptake in both in vitro and in vivo models, but folic acid inhibition could not establish the target specificity.
