HPLC of Formula: 693-67-4. The reaction of aromatic heterocyclic molecules with protons is called protonation. Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms. Compound: 1-Bromoundecane, is researched, Molecular C11H23Br, CAS is 693-67-4, about Synthesis of VO2/Poly(MMA-co-dMEMUABr) antimicrobial/thermochromic dual-functional coatings. Author is Liu, Yixian; Xu, William Z.; Charpentier, Paul A..

In order to address the need for window coatings that can control room temperature while being self-cleaning, this work examined a dual-functional antimicrobial/thermochromic coating. The goal was addressed by chem. polymerizing the antimicrobial agent, quaternary ammonium compound (QAC) N,N-dimethyl-N-{2-[(2-methylprop-2-enoyl)oxy]ethyl}undecane-1-aminium bromide (dMEMUABr) while using vanadium dioxide (VO2) as the thermochromic agent. The antimicrobial agent dMEMUABr, having an acrylic moiety and a long hydrocarbon tail for enhanced killing, was synthesized and characterized by NMR and FTIR spectroscopies. VO2 nanoparticles were synthesized hydrothermally and characterized by physicochem. anal. including powder XRD, DSC and SEM. Polymer coatings were obtained by polymerizing dMEMUABr with Me methacrylate (MMA) monomer under UV irradiation with the required UV curing time being investigated. Thermochromic performance of dual-functional VO2/poly(MMA-co-dMEMUABr) coating gave an IR modulation ΔTIR of 5.8% and luminous transmittance Tlum of 36.1% at 25°C. The antimicrobial testing of the dual-functional coating indicated that it could kill 90.3% of bacteria Escherichia coli (E. coli) within 24 h at a low dMEMUABr concentration (3.8 wt % relative to MMA). The zone of inhibition test proved the contact kill principle of the coating, without releasing toxic antimicrobial agents to the environment.

Compound: 1-Bromoundecane, is researched, Molecular C11H23Br, CAS is 693-67-4, about Multiresponse Shape-Memory Nanocomposite with a Reversible Cycle for Powerful Artificial Muscles.

In the field of bionic soft robots and microrobots, artificial muscle materials have exhibited unique potential for cutting-edge applications. However, current mainstream thermal-responsive artificial muscles based on semicrystalline polymers (SCPs), despite their excellent phys. properties, suffer from the limitation of environmental stimuli in practice, while their photodriven counterparts adopting liquid crystal elastomers (LCEs) lack ductility. Herein, a novel multifunctional programmable artificial muscle with a unique patch-sewing structure formed by π-π stacking between azobenzene groups was designed, which combined the advantages of SCPs and LCEs. The nanocomposite demonstrated a unique combination between artificial muscle performance (46.5 times the energy d. and 26.6 times the power d. of human skeletal muscles) and programmability (274.84% strain and 100% shape-memory recovery rate within 1 s). Meanwhile, coupling the photoisomerization of azobenzene and the photothermal conversion of gold nanorods, the cycle of deformation triggered by UV light and restoring by IR light could be accomplished rapidly within 30 s. A COMSOL Multiphysics model was established and the corresponding finite element anal. verified the photoactuation and captured the general principle of light initiation in elastomers. These demonstrate that the multifunctional programmable elastomer is promising for artificial muscle applications, especially for photoinduced actuation.

Compounds whose heterocycles in the molecular skeleton cannot reflect aromaticity are called alicyclic heterocyclic compounds. Compound: 693-67-4, is researched, Molecular C11H23Br, about Effect of n-alkyl substitution on Cu(II)-selective chemosensing of rhodamine B derivatives, the main research direction is alkyl substitution copper fluorescent sensor rhodamine B derivative.Recommanded Product: 693-67-4.

Rhodamine B hydrazide-based mol. probes (1-10) were synthesized by derivatization with n-alkyl chains of different lengths at the hydrazide amino end. These probes exhibited selective absorption (A∼557) and fluorescence (I∼580) ‘off-on’ signal transduction along with a colorless → magenta color transition in the presence of Cu(II) ions among all the competitive metal ions investigated. The effective coordination of these probes to Cu(II) ions under the investigated environment forming [Cu·L]2+ (L = 1-5) and [Cu·L2]2+ (L = 6-10) complexes led to their spiro-ring opening, which in turn was expressed through signatory spectral peaks of ring-opened rhodamine. All these probes exhibited Cu(II) selectivity in signalling despite structural modifications to the core receptor unit through variation of the nature of the alkyl substituents. However, the sensitivity of the signalling and kinetics of the spiro-ring opening varied and could be correlated with the number of carbon atoms present in the n-alkyl substituents. Structural elucidation with X-ray diffraction and X-ray photoemission spectroscopic analyses provided further insight into the structure-function correlation in their Cu(II) complexes. These probes with Cu(II) coordination showed selectivity in signalling, high complexation affinity (log Ka = 4.8-8.8), high sensitivity (LOD = 4.1-80 nM), fast response time (rate = 0.0017-0.0159 s-1) and reversibility with counter anions, which ascertained their potential utility as chemosensors for Cu(II) ion detection.

In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Anisotropic, Organic Ionic Plastic Crystal Mesophases from Persubstituted Imidazolium Pentacyanocyclopentadienide Salts, published in 2019-12-10, which mentions a compound: 693-67-4, mainly applied to persubstituted imidazolium pentacyanocyclopentadienide salt anisotropic organic ionic plastic crystal, Formula: C11H23Br.

We describe the synthesis, supramol. organization, and thermal characteristics of an unprecedented family of sym. 1,2,3,4,5-pentaalkylimidazolium ([(Cn)5i.m.]+) salts equipped with halide, nitrate, or pentacyanocyclopentadienide ([Cp(CN)5]-) counterions. Salts containing relatively small anions were obtained as low-melting solids, whereas those with [Cp(CN)5]- anions were found to be ionic liquids even below room temperature A permethylated derivative, [(C1)5i.m.][Cp(CN)5], proved to be exceptional. Upon heating, the salt self-organized into a new type of organic ionic plastic crystal (OIPC) mesophase, which was termed Mhex and whose anisotropic structure featured hexagonally ordered, rotating anionic stacks positioned within a continuum composed of disordered cations. The structure of the mesophase resembles that of classical columnar liquid-crystalline phases, despite the absence of long, flexible chains. In the Mhex phase, the cations surrounding the anionic columns effectively fulfill the role of “”softening”” structural constituents, much in the same way as flexible chains. The discovery of the novel mesophase, which displays a two-dimensional, and thus intrinsically anisotropic, lattice resulting from the rotation of entire ionic assemblies around a columnar axis, represents a new paradigm in the field of OIPCs. Relatively high ionic conductivities were measured in the Mhex phase, particularly after doping with the corresponding sodium salt, Na[Cp(CN)5], demonstrating the materials’ potential for use in electrochem. applications such as sodium-ion batteries.

The synthesis of series of lipophilic phenothiazine analogs I (n = 4, 5, 6, 8) that potently inhibit ferroptosis was reported in the present study. The most promising compounds I exhibited an improved protection compared to the parent phenothiazine against erastin- and RSL3-induced ferroptotic cell death. These analogs have equivalent or better potency than ferrostatin-1 (Fer-1) and liproxstatin-1 (Lip-1), which are among the most potent inhibitors of this regulated cell death described so far. They represent novel lead compounds with therapeutic potential in relevant ferroptosis-driven disease models such as FRDA.
