Author is Bhowmik, Pradip K.; Noori, Omar; Chen, Si L.; Han, Haesook; Fisch, Michael R.; Robb, Christina M.; Variyam, Aaron; Martinez-Felipe, Alfonso.

A series of asym. viologen bistriflimide salts I (R = n-pentyl, dodecyl, octadecyl, etc.) of both short and long alkyl chains were synthesized by the metathesis reaction of lithium triflimide salt with the resp. asym. viologen dibromide salts II in methanol. Their thermotropic liquid crystalline properties were determined by differential scanning calorimetry, polarizing optical microscopy and variable temperature X-ray diffraction techniques. These salts melt into highly-ordered smectic T phases i.e., crystal-to SmT transitions (Tms) at relatively low temperatures (lowest Tm at -12°C) and maintain liquid crystallinity in a wide range of temperatures (8-132°C), with excellent thermal stabilities up to 320°C as determined by thermogravimetric anal. These results differ with respect to the sym. viologen bistriflimide salts I. Ionic conductivity of these salts was also measured by dielec. impedance spectroscopy and found to be in the 10-2.5 S cm-1 range, highlighting their potential as electrolytes at room temperature

Category: tetrahydroisoquinoline. Aromatic heterocyclic compounds can also be classified according to the number of heteroatoms contained in the heterocycle: single heteroatom, two heteroatoms, three heteroatoms and four heteroatoms. Compound: 1-Bromoundecane, is researched, Molecular C11H23Br, CAS is 693-67-4, about Screening Libraries of Amphiphilic Janus Dendrimers Based on Natural Phenolic Acids to Discover Monodisperse Unilamellar Dendrimersomes. Author is Buzzacchera, Irene; Xiao, Qi; Han, Hong; Rahimi, Khosrow; Li, Shangda; Kostina, Nina Yu.; Toebes, B. Jelle; Wilner, Samantha E.; Moller, Martin; Rodriguez-Emmenegger, Cesar; Baumgart, Tobias; Wilson, Daniela A.; Wilson, Christopher J.; Klein, Michael L.; Percec, Virgil.

Natural, including plant, and synthetic phenolic acids are employed as building blocks for the synthesis of constitutional isomeric libraries of self-assembling dendrons and dendrimers that are the simplest examples of programmed synthetic macromols. Amphiphilic Janus dendrimers are synthesized from a diversity of building blocks including natural phenolic acids. They self-assemble in water or buffer into vesicular dendrimersomes employed as biol. membrane mimics, hybrid and synthetic cells. These dendrimersomes are predominantly uni- or multilamellar vesicles with size and polydispersity that is predicted by their primary structure. However, in numerous cases, unilamellar dendrimersomes completely free of multilamellar assemblies are desirable. Here, we report the synthesis and structural anal. of a library containing 13 amphiphilic Janus dendrimers containing linear and branched alkyl chains on their hydrophobic part. They were prepared by an optimized iterative modular synthesis starting from natural phenolic acids. Monodisperse dendrimersomes were prepared by injection and giant polydisperse by hydration. Both were structurally characterized to select the mol. design principles that provide unilamellar dendrimersomes in higher yields and shorter reaction times than under previously used reaction conditions. These dendrimersomes are expected to provide important tools for synthetic cell biol., encapsulation, and delivery.

Synthetic Route of C11H23Br. 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 Monodisperse micelles composed of poly(ethylene glycol) attached surfactants: platonic nature in a macromolecular aggregate. Author is Lee, Ji Ha; Matsumoto, Hayata; Fujii, Shota; Takahashi, Rintaro; Sakurai, Kazuo.

Among the many studies on micelles, dating back more than 100 years, we first found a series of monodisperse micelles: spherical micelles made from calix[4]arene surfactants exhibited monodispersity in aggregation number (Nagg) with values of 4, 6, 8, 12, and 20. We named these Platonic micelles because these values coincided with the face numbers of the Platonic solids. The preferred Nagg values were explained in relation to the math. Tammes problem: how to obtain the best coverage of a sphere surface with multiple identical circles. In this paper, we synthesized poly(ethylene glycol)-attached surfactants and carried out small-angle X-ray scattering (SAXS) and anal. ultracentrifugation (AUC) to determine the Nagg. We found that these polymeric surfactants also formed monodispersed micelles and Nagg discontinuously increased from 20 to 24, and then 32 with increasing the alkyl carbon numbers from 9 to 11 continuously. The determined Nagg was greater than 20 and the Platonic solid numbers We assumed that the preferred Nagg values could be explained in relation to the Tammes problem as well.

Author is Tahtaci, Hakan; Aydin, Gozde.

In this study, a new series of substituted 1,3,4-thiadiazol-2(3H)-one derivatives I [R = Et, CH2CH=CH2, cyclohexylmethyl, etc.] was synthesized in yields ranging from 42 to 70% via reaction of alkyl bromides with 1-(4-chlorophenyl)-2-((5-methyl-1,3,4-thiadiazol-2-yl)thio)ethanol with an interesting mechanism that involved internal nucleophilic substitution followed by an SN2-type nucleophilic substitution. First, 1-(4-chlorophenyl)-2-((5-methyl-1,3,4-thiadiazol-2-yl)thio)ethanone was synthesized from the reaction of 5-methyl-1,3,4-thiadiazole-2-thiol with 2-bromo-1-(4-chlorophenyl)ethanone which underwent reduction to afford 1-(4-chlorophenyl)-2-((5-methyl-1,3,4-thiadiazol-2-yl)thio)ethanol. The advantages of this protocol were synthesis of target compounds under mild conditions using simple synthetic methods and obtaining them without phosgene.

HPLC of Formula: 693-67-4. So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic. Compound: 1-Bromoundecane, is researched, Molecular C11H23Br, CAS is 693-67-4, about Cold Crystallization and Polymorphism Triggered by the Mobility of the Phenyl Group in Alkyl Azo Dye Molecules.

The thermal behavior, including the cold crystallization, of alkyl-derivatized Sudan III (1-[4-(phenylazo)phenylazo]-2-naphthol), SD3-OCn, was investigated. Its structural flexibility due to the two azo groups caused the formation of plural crystal structures, which further resulted in complex cold crystallization A metastable nonflat structure and a thermodynamically stable flat structure resulted in the two sets of crystallization and melting behavior during the heating process. Further, the change in the alkyl chain length caused variations in the crystallization rate and crystallinity, thus systematically changing the cold crystallization behavior. It was proven that the high mobility of the Ph group triggered supercooling and cold crystallization and that the alkyl chain correspondingly controlled the thermal behavior.

The chemical properties of alicyclic heterocycles are similar to those of the corresponding chain compounds. Compound: 1-Bromoundecane, is researched, Molecular C11H23Br, CAS is 693-67-4, about One-step zwitterionization and quaternization of thick PDMAEMA layer grafted through subsurface-initiated ATRP for robust antibiofouling and antibacterial coating on PDMS, the main research direction is grafted PDMAEMA subsurface initiated atom transfer radical polymerization; zwitterionization quaternization antibiofouling bacterial coating PDMS; Dual-functions; One-step zwitterionization and quaternization; Self-migration; Subsurface-initiated ATRP; Thick layer.Computed Properties of C11H23Br.

In this work, we demonstrate the grafting of thick poly((2-dimethylamino) Et methacrylate) (PDMAEMA) layer on PDMS via subsurface-initiated atom transfer radical polymerization (SSI-ATRP). The self-migration of DMAEMA monomers into the subsurface of PDMS is proven to be the dominant factor for the success of SSI-ATRP. The as-prepared thick microscale graft layer on PDMS shows much better abrasion resistance than nanoscale graft layer obtained by conventional surface-initiated atom transfer radical polymerization (SI-ATRP) under identical condition. Taking advantage of the tertiary amines of PDMAEMA, the simultaneous zwitterionization and quaternization of the PDMAEMA thick layer is realized through a facile one-step process. The effect of zwitterionization and quaternization degree on the antibiofouling and antibacterial properties is investigated. The results show that a relatively high zwitterionization degree (75 mol%) and a low quaternization degree (25 mol%) exhibit a good well-balanced effect on both fouling repellence and bactericidal activity. This work may lead to the development of robust bifunctional antibiofouling and antibacterial surfaces via SSI-ATRP strategy.
