Control of planar chirality: The construction of a copper-ion-controlled chiral molecular hinge

(Figure Presented) An open-and-closed case: When a chiral clamp is attached to a molecular hinge the open-close motion induced by coordination to a metal ion becomes unidirectional (see scheme). The large change in amplitude caused by the unidirectional rotation and the relatively simple preparation of the hinge open up the possibility of using this concept for even more-complex molecular machines.

A new dual probe for hydrogen abstraction

A new dual (fluorescent and spin) probe is described, where a N-aryl-2,4,6-triphenylpyridinium fluorophore is attached to a TEMPO fragment through an amide link. The resulting sensor 4 was evaluated as a hydrogen-abstracting agent in acetonitrile and in an aqueous solution of reduced Triton-X 100, being as resistant to hydrolysis as quinoline-TEMPO 1, but more hydrophobic than this probe.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Quality Control of: 2,4,6-Triphenylpyrylium tetrafluoroborate, you can also check out more blogs about448-61-3

Reactive Oxygen Species (ROS)-vs Peroxyl-Mediated Photosensitized Oxidation of Triphenylphosphine: A Comparative Study

The oxidation of triphenylphosphine in the presence of various photocatalytic systems (dicyanoanthracene/biphenyl, N-methylquinolinium, triphenylpyrylium, and thiatriphenylpyrylium tetrafluoroborate) was investigated by means of both steady state and laser flash photolysis experiments. The effect of different additives (including 1,4-benzoquinone, diphenylsulfoxide, tetramethylethylene, and sodium azide) on the photosensitized oxidation was investigated in order to fully characterize the involved intermediates. Photoinduced electron transfer and final regeneration of the catalyst occur when dicyanoanthracene and N-methylquinolinium are used, while in cage oxygen transfer to the photoexcited (thio)pyrylium derivatives have been characterized in the last two cases.

The biodegradation of monomeric and dimeric alkylammonium surfactants

Quaternary ammonium compounds (QACs) are salts known for having antiseptic and disinfectant properties. These compounds are toxic to aquatic organisms and should thus be removed from wastewater before its discharge into surface waters. The biodegradation of QACs takes place in the presence of microorganisms under aerobic conditions. The susceptibility of these compounds to degradation depends on numerous parameters. A number of them, such as the structure-adsorption on solids, and concentration of the QACs, as well as the presence of additional substances, have been reviewed in this article. Moreover, the biodegradability of new dimeric alkylammonium salts, i.e., cationic gemini surfactants, has been discussed and compared with that of anionic and nonionic geminis. The biodegradation study of monomeric and dimeric alkylammonium surfactants show that they are not easily degraded. The degradation process is very complex and strongly depends on the structure of the compound, adsorption-desorption processes on sludge, type of microorganism consortia and the presence of anions. Alkylammonium surfactants with biological motifs, like amide, peptides or carbohydrates, are much better degraded.

Enzymes are biological catalysts that produce large increases in reaction rates and tend to be specific for certain reactants and products. I hope my blog about is helpful to your research. Quality Control of: MitMAB

Cu(ii)-: TBu-PHOX catalyzed enantioselective malonate addition onto 3-hydroxy 2-oxindoles: Application in the synthesis of dimeric pyrroloindoline alkaloids

An efficient Cu(ii)-PHOX-catalyzed malonate addition onto 3-hydroxy 3-indolyl-2-oxindoles is envisioned to afford excellent enantioselectivities (up to >99% ee) in high chemical yields. Detailed characterization techniques including X-ray, NMR, CV and EPR experiments suggest that a Cu(ii)-complex is involved as an active species in this process. Applying this strategy, an advanced intermediate of cyclotryptamine alkaloids has been synthesized in few steps for a general approach to bis-cyclotryptamine alkaloids.

Surfactant-assisted selective etching strategy for generation of rattle-like mesoporous silica nanoparticles

Nowadays, rattle-like or so-called yolk-shell nanostructures have set off a new wave of research in view of their prominent features including large surface area, tunable void and flexible functional core, etc. Herein, rattle-like mesoporous silica nanoparticles (RMSNs) with a pure silica core, a hollow cavity and a mesoporous shell have been successfully fabricated via a surfactant-assisted selective etching strategy. The synthetic approach involves the preparation of solid silica spheres with three-layer different structural silica containing the inner core of pure silica, middle layer of hybrid silica and outer shell of surfactant/SiO2 composite, followed by a hydrothermal treatment in hot water. The resulting products show a distinct rattle-like structure and spherical morphology. The average diameter, the shell thickness, and the solid core size of RMSNs are about 290, 35 and 90 nm, respectively. During the etching process, the surfactant with different length of alkyl chain (CnTAB, e.g. cetyltrimethylammonium bromide) in outer shell plays a decisive role for the formation of rattle-like structure. Benefiting from the residual amino groups in RMSNs, Au@RMSNs composites can be further constructed by in-situ generating Au nanoparticles into their hollow cavity, demonstrating an excellent catalytic performance for reduction of 4-nitrophenol. Additionally, RMSNs also show a strong ability for adsorption of rhodamine B.

Effect of external high pressures on the clay mineral sodium montmorillonite intercalated with methylated octadecylammonium bromide surfactants

Raman microprobe spectra of the clay mineral Wyoming SWy-2-sodium montmorillonite intercalated with the surfactants, methyltrioctadecylammonium bromide (TOMA) dimethyldiotadecylammonium bromide (DODMA) and octadecyl-trimethylammonium bromide (ODTMA), have been measured in the CH 2 stretching region at external pressures up to ?40 kbar with the aid of a diamond-anvil cell. In the case of the intercalated clays containing TOMA and DODMA, the Raman data afford evidence for gauche to trans conformational changes in the orientation of the CH2 chains in the surfactants with increasing pressure. These conformational changes are reversed completely upon the release of pressure.
