Mukherjee, Attreyee; Mahalanabis, Kumar K. published the artcile< Systematic study on acylation of methyl 3-aminocrotonate with acid chlorides of aliphatic, aromatic and α,β-unsaturated acids: a comparative evaluation of the preference for regio- and stereoselectivity vis-a'-vis 3-aminocrotononitrile>, Name: (E)-Cinnamoyl chloride, the main research area is methyl aminocrotonate regioselective diastereoselective acylation.

Acylation of Me 3-aminocrotonate in benzene with a variety of aliphatic and aromatic acid chlorides including α,β-unsaturated acid chloride in the presence of an added organic base, (either pyridine or triethylamine) was reported. The preferred N, C-site selectivity in these reactions was compared with the terminal selectivity of the products obtained previously on acylation of Me 3-aminocrotononitrile. A strong preference either for N- or C- selectivity in N, C-acylation was observed for both Me 3-aminocrotonate and Me 3-aminocrotononitrile based on the choice of acid chlorides and added organic base. Interestingly, irresp. of the enamine Me 3-aminocrotonate or Me 3-aminocrotononitrile, acylation with α,β-unsaturated acid chlorides in the presence of triethylamine afforded 3,4-dihydropyridin-(2H)-one via [3.3] sigmatropic rearrangement of the corresponding intermediary N(E)-enamide. Accrued results showed Me 3-aminocrotonate to be a better precursor for preparation of enamides (N-acylated products) whereas 3-aminocrotononitrile was found to be a preferred choice for preparation of enaminones (C-acylated products). An attempt was made to offer a preliminary theor. interpretation for observed site selectivity.

Li, Tianming; Yao, Zhengjun; Zhou, Jintang published the artcile< Preparation and characterization of a novel composite of polythioetherimide/bismaleimide/2,2'-diallylbisphenol A>, COA of Formula: C8H3ClO3, the main research area is polythioetherimide bismaleimide diallylbisphenol composite preparation thermomech property.

A novel composite of polythioetherimide (PTEI)/bismaleimide (BMI)/2,2′-diallylbisphenol A (BA) was prepared Mech. measurements, dynamic thermomech. anal., and microanal. were conducted to assess the toughness and morphol. of the composite. Results demonstrate that the addition of PTEI has significant effects on the mech. properties of the BMI/BA system. Compared with the BMI/BA resin, the PTEI/BMI/BA system significantly improves the impact strength and bending strength, given an appropriate amount of PTEI. Scanning electron microscope (SEM) images and energy dispersive spectroscopy results show that PTEI is distributed uniformly in the PTEI/BMI/BA system and that the interfacial compatibility between the PTEI and BMI/BA phase is excellent. Thermogravimetric and dielec. analyses were also conducted to infer the thermal and dielec. properties of the composite. With a suitable addition of PTEI, the BMI/BA resin still exhibits good thermal resistance and dielec. constant and loss values of the blends still retain good stability in a frequency band from 10 MHz to 60 MHz. All these changes in properties are closely correlated with the addition of PTEI.

Sen, Sudeshna; Goodwin, Sean E.; Barbara, Pedro Verdia; Rance, Graham A.; Wales, Dominic; Cameron, Jamie M.; Sans, Victor; Mamlouk, Mohamed; Scott, Keith; Walsh, Darren A. published the artcile< Gel-Polymer Electrolytes Based on Poly(Ionic Liquid)/Ionic Liquid Networks>, Formula: C9H9Cl, the main research area is gel polymer electrolyte ionic liquid conductivity crosslinking membrane.

The use of elec. charged, polymerized ionic liquids (polyILs) offers opportunities for the development of gel-polymer electrolytes (GPEs), but the rational design of such systems is in its infancy. In this work, we compare the properties of polyIL/IL GPEs based on 1-butyl-3-(4-vinylbenzyl)imidazolium bis(trifluromethanesulfonyl)imide containing trapped ammonium-based protic ionic liquids (ILs) with an analogous series based on the elec. neutral host polymer 1-(4-vinylbenzyl)imidazole. The materials are synthesized by photopolymerizing ionic and neutral monomers in the presence of diethylmethylammonium trifluoromethanesulfonate, [dema][TfO], diethylmethylammonium trifluoroacetate, [dema][TFAc], and diethylmethylammonium bis[trifluoromethanesulfonyl]imide, [dema][Tf2N], resp. The resulting materials are characterized using electron microscopy, IR spectroscopy, thermal anal., Raman spectroscopy, and AC-impedance anal. Spectroscopic anal. confirms that the ILs are distributed throughout the polymers, unless the GPE also contains poly(diallyldimethylammonium) bis[trifluoromethanesulfonyl]imide, when separation of the components occurs. The polyIL/IL GPEs are more electrochem. and thermally stable, and up to six times more conductive, than the materials based on the neutral host. As a proof-of-concept demonstration, we show that polyIL/IL gels can be 3D printed using readily available 3D-printing hardware.

Potent DNA minor-groove binding antibacterials, e.g. I (R = aryl, heteroaryl), were designed based on the natural product distamycin A and synthesized, and their structure-activity relationship was investigated. These compounds have been shown to target A/T-rich sites within the bacterial genome and, as a result, inhibit DNA replication and RNA transcription. The optimization was focused on N-terminal aromatic heterocycles and C-terminal amines and resulted in compounds with improved in vivo tolerability and excellent in vitro antibacterial potency (MIC ≥ 0.031 μg/mL) against a broad range of Gram-pos. pathogens, including drug-resistant strains such as methicillin-resistant Staphylococcus aureus, penicillin-resistant Streptococcus pneumoniae, and vancomycin-resistant Enterococcus faecalis. In a first proof-of-concept study, I (R = 3-chloro-2-thienyl) showed in vivo efficacy in a mouse peritonitis model against methicillin-sensitive S. aureus infection with an ED50 value of 30 mg/kg.

Ju, Changha; Park, Chanhyuk; Kim, Taehyung; Kang, Shinwoo; Kang, Hyo published the artcile< Thermo-responsive draw solute for forward osmosis process; poly(ionic liquid) having lower critical solution temperature characteristics>, Synthetic Route of 1592-20-7, the main research area is polyvinylbenzyltributylammonium hexanesulfonate osmosis viscosity water desalination.

We synthesized poly(4-vinylbenzyltributylammonium hexanesulfonate) (P[VBTBA][HS]), a poly(ionic liquid) that shows lower critical solution temperature (LCST), via the anion exchange reaction of poly(4-vinylbenzyltributylammonium chloride) (P[VBTBA][Cl]) with sodium hexanesulfonate in order to investigate its suitability as a draw solute for the forward osmosis (FO) process. P[VBTBA][Cl] was obtained by the free radical polymerization of (4-vinylbenzyltributylammonium chloride [VBTBA][Cl]) monomer acquired by the Menshutkin reaction. The FO performance and recovery properties of the synthesized materials were systematically investigated. For example, the LCST of P[VBTBA][HS] was observed to be ∼17°C at 20 wt%, while no LCST was observed for [VBTBA][Cl] monomer and P[VBTBA][Cl] polymer before the anion exchange reaction, indicating that P[VBTBA][HS] can be recovered from the aqueous solution by heating it to above its LCST. Moreover, in an active layer facing the feed solution (AL-FS) system containing 20 wt% aqueous P[VBTBA][HS] solution at 15°C, the water flux and reverse solute flux of P[VBTBA][HS] were found to be ∼5.85 L m-2 h-1 and 1.13 g m-2 h-1, resp. Therefore, we studied the feasibility of using the poly(ionic liquid), a homopolymer having LCST characteristics, as a draw solute in the FO process.

Peltekoff, Alexander J.; Hiller, Victoria E.; Lopinski, Gregory P.; Melville, Owen A.; Lessard, Benoit H. published the artcile< Unipolar Polymerized Ionic Liquid Copolymers as High-Capacitance Electrolyte Gates for n-Type Transistors>, Product Details of C9H9Cl, the main research area is unipolar polymerized ionic liquid copolymer capacitance electrolyte transistor.

A series of well-defined polymerized ionic liquid (PIL) statistical and block copolymers consisting of ionic liquid monomer, 1-(4-vinylbenzyl)-3-butylimidazolium bis(trifluoromethylsulfonyl)imide, and a nonionic monomer, Me methacrylate (MMA), were synthesized by nitroxide-mediated polymerization (NMP) with the goal of understanding the influence of polymer structure on the thin film capacitance. Copolymer compositions were varied from 8 to 54 weight % for both statistical and block copolymers and were characterized by predictable changes in glass transition temperature (75 °C > Tg > 45 °C). When integrated into thin film capacitors, block copolymers exhibited the formation of elec. double layer (EDL) at lower frequencies compared to the statistical copolymers of similar comonomer compositions The materials that formed an EDL all produced a similar maximum double layer capacitance value, with the only difference being the frequency at which the EDL was formed. Finally, the PIL-containing materials that were utilized in organic thin-film transistors (OTFTs) showed a significant reduction in operating voltage compared to the poly(MMA) baseline. These results indicate that not only composition but also polymer architecture plays a vital role in the formation of an EDL and determines at which frequency the resulting OTFTs can be operated.
