The use of polymeric nanoparticles (NPs) as therapeutics has been steadily increasing over past decades. In vivo imaging of NPs is necessary to advance the therapeutic performance. 19F Magnetic Resonance Imaging (19F MRI) offers multiple advantages for in vivo imaging. However, design of a probe for both biodistribution and degradation has not been realized yet. We developed polymeric NPs loaded with two fluorocarbons as promising imaging tools to monitor NP biodistribution and degradation by 19F MRI. These 200 nm NPs consist of poly(lactic-co-glycolic acid) (PLGA) loaded with perfluoro-15-crown-5 ether (PFCE) and PERFECTA. PERFECTA/PFCE-PLGA NPs have a fractal sphere structure, in which both fluorocarbons are distributed in the polymeric matrix of the fractal building blocks, which differs from PFCE-PLGA NPs and is unique for fluorocarbon-loaded colloids. This structure leads to changes of magnetic resonance properties of both fluorocarbons after hydrolysis of NPs. PERFECTA/PFCE-PLGA NPs are colloidally stable in serum and biocompatible. Both fluorocarbons show a single resonance in 19F MRI that can be imaged separately using different excitation pulses. In the future, these findings may be used for biodistribution and degradation studies of NPs by 19F MRI in vivo using ?two color? labeling leading to improvement of drug delivery agents.

We report a continuous-flow protocol for the trifluoromethylation of arenes, heteroarenes, and benzofused heterocycles. This photoredox methodology relies on the use of solid sodium trifluoromethanesulfinate (CF 3 SO 2 Na) as the trifluoromethylating agent and the iridium complex [Ir{dF(CF 3)ppy} 2 ](dtbpy)]PF 6 as the photoredox catalyst. A diverse set of highly functionalized heterocycles proved compatible with the methodology, and moderate to good yields were obtained within 30 minutes of residence time.

Chemistry is traditionally divided into organic and inorganic chemistry. name: Sodium trifluoromethanesulfonate. The former is the study of compounds containing at least one carbon-hydrogen bonds.In a patent，Which mentioned a new discovery about 2926-30-9

PolyTHF terminated by a quaternary ammonium triflate group was used as an anion exchanging material. The polymer was deposited using a dip coating method on the surface of a silica/silicon heterostructure whose impedance characterization could be performed. Capacitance measurements of the siliconsulator (silica and polymeric layer)?ectrolyte heterostructure allowed the studying of the anion-exchange phenomena at the cationic groups in the functional polyTHF membrane. Both increases of the polymer layer thickness and dielectric permittivity were observed by impedance measurements due to swelling of the polymeric film when the electrode was immersed in a sodium triflate solution. In the first part, exchange phenomena of the triflate anion against anions-acetate, nitrate, methane sulfonate, Acid Blue 25 dye, and sulfate-in a sodium triflate background electrolyte solution was investigated. Specific ion exchange was observed according to the anion type. In the second part, ion-exchange phenomena have been studied in a sodium acetate background electrolyte solution after initial swelling and partial ion exchange of the triflate against acetate anion. The capacitance measurements (flat-band potential shift) were allowed to distinguish between triflate-anion and acetate-anion exchange phenomena.

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.Recommanded Product: 2926-30-9, you can also check out more blogs about2926-30-9

Rhenium(I) compounds [Re(CO)3(Hdmpz)2(ampy)] BAr?4 and [Re(CO)3(N-MeIm)2(ampy)] BAr?4 (Hdmpz = 3,5-dimethylpyrazole, N-MeIm = N-methylimidazole, ampy = 2-aminopyridine or 3-aminopyridine) have been prepared stepwise as the sole reaction products in good yields. The cationic complexes feature two different types of hydrogen bond donor ligands, and their anion binding behavior has been studied both in solution and in the solid state. Compounds with 2-ampy ligands are labile in the presence of nearly all of the anions tested. The X-ray structure of the complex [Re(CO)3(Hdmpz) 2(ampy)]+ (2) shows that the 2-ampy ligand is metal-coordinated through the amino group, a fact that can be responsible for its labile character. The 3-ampy derivatives (coordinated through the pyridinic nitrogen atom) are stable toward the addition of several anions and are more selective anion hosts than their tris(pyrazole) or tris(imidazole) counterparts. This selectivity is higher for compound [Re(CO)3(N-MeIm) 2(MeNA)]BAr?4 (5·BAr?4, MeNA = N-methylnicotinamide) that features an amido moiety, which is a better hydrogen bond donor than the amino group. Some of the receptor-anion adducts have been characterized in the solid state by X-ray diffraction, showing that both types of hydrogen bond donor ligands of the cationic receptor participate in the interaction with the anion hosts. DFT calculations suggest that coordination of the ampy ligands is more favorable through the amino group only for the cationic complex 2, as a consequence of the existence of a strong intramolecular hydrogen bond. In all other cases, the pyridinic coordination is clearly favored.

We have designed and prepared a new dual stimuli-responsive guest molecule containing a spiropyran fragment and a pyridinium moiety. Acid addition or UV-light irradiation induces guest transformation to a merocyanine isomer, promoting the threading motion through a 24-crown-8 macrocycle and the formation of a [2]pseudorotaxane complex.

Sodium-based batteries are promising for grid-storage applications because of significantly lower cost compared to lithium-based systems. The advancement of solid-state and redox-flow sodium-ion batteries requires sodium-ion exchange membranes with high conductivity, electrochemical stability, and mechanical robustness. This study demonstrates that membranes based on poly(ethylene oxide) (PEO) can meet these requirements. Membranes plasticized with tetraethylene glycol dimethyl ether (TEGDME) achieve high ionic conductivity. Plasticized PEO membranes containing sodium triflate salt (NaTFS) show about 2 orders of magnitude higher conductivity compared to nonplasticized PEO membranes. Results from vibrational spectroscopy and differential scanning calorimetry describe the coordination chemistry in these multiphase materials and explain the mechanisms behind the increased conductivity. The mechanical properties of the membranes improve by addition of 5 wt % sodium carboxymethyl cellulose (CMC) without compromising the conductivity or electrochemical stability against sodium metal. The optimized membrane is an excellent candidate for low-cost energy storage systems that operate over a wide voltage window near ambient temperature.

Chemoselective synthesis and isolation of alkynyl [Cp*Ir III(bpy)CCPh]+ (2, Cp* = eta5-C 5Me5, bpy = 2,2?-bipyridine), acyl [Cp*Ir III(bPy)C(O)CH2Ph]+ (3), and ketonyl [Cp*IrIII(bpy)CH2C(O)Ph]+ (4) intermediates in anti-Markovnikov and Markovnikov hydration of phenylacetylene in water have been achieved by changing the pH of the solution of a water-soluble aqua complex [Cp*IrIII(bpy)(H2O)] 2+ (1) used as the same starting complex. The alkynyl complex [2]2·SO4 was synthesized at pH 8 in the reaction of 1·SO4 with H2O at 25 C, and was isolated as a yellow powder of 2·X (X = CF3SO3 or PF 6) by exchanging the counteranion at pH 8. The acyl complex [3] 2·SO4 was synthesized by changing the pH of the aqueous solution of [2]2·SO4 from 8 to 1 at 25C, and was isolated as a red powder of 3·PF6 by exchanging the counteranion at pH 1. The hydration of phenylacetylene with 1·SO4 at pH 4 at 25C gave a mixture of [4] 2·SO4 and [4]2·SO4. After the counteranion was exchanged from SO42- to CF 3SO3-, the ketonyl complex 4·CF 3SO3 was separated from the mixture of 2·CF 3SO3 and 4·CF3SO3 because of the difference in solubility at pH 4 in water. The structures of 2-4 were established by IR with 13C-labeled phenylacetylene (Ph 12C?13CH), electrospray ionization mass spectrometry (ESI-MS), and NMR studies including 1H, 13C, distortionless enhancement by polarization transfer (DEPT), and correlation spectroscopy (COSY) experiments. The structures of 2·PF6 and 3·PF6 were unequivocally determined by X-ray analysis. Protonation of 3 and 4 gave an aldehyde (phenylacetaldehyde) and a ketone (acetophenone), respectively. Mechanism of the pH-selective anti-Markovnikov vs Markovnikov hydration has been discussed based on the effect of pH on the formation of 2-4. The origins of the alkynyl, acyl, and ketonyl ligands of 2-4 were determined by isotopic labeling experiments with D2O and H 218O.

Sodium-conducting solvent-free polymer electrolytes based on commercially available and inexpensive materials poly(oxyethylene), POE, and three different sodium salts (NaI, NaCF3SO3 and NaClO4) were prepared and exhaustively characterized. In order to minimize the environmental impact related to conventional film processing based on casting, a combination of lyophilization and hot-pressing was successfully applied. Contrary to film-casting, this new approach led to very homogeneous and pore-free films. This study suggests the obtained polymer electrolyte films as a promising route to enhance not only ionic conductivity but also mechanical properties. Furthermore, a preliminary work on salt blends hosted by POE shows that they strongly decrease melting point and crystallinity of the polymer electrolytes and paves the way for enhanced sodium-conducting materials.

In comparison to beta-diketiminates, a highly exploited class of N,N-chelating ligands, the corresponding beta-thioketoiminates, monothio-substituted analogues, have received only minor attention. beta-Thioketoiminates are straightforwardly prepared through treatment of an appropriate beta-ketoiminate with Lawesson’s reagent. Employing standard synthetic techniques for eta6-arene Ru(II) and Os(II) beta-diketiminate complexes, an analogous series of chlorido-metal complexes supported by different sized N-aryl substituted beta-thioketoiminate ligands is reported. However, metal ligation of a beta-thioketoiminate bearing an electron-withdrawing CF3 group was not possible. The metal-chlorine bond in these complexes is readily activated by various sodium or silver salts of weakly coordinating anions, affording coordinately unsaturated cationic formally 16-electron species. All eta6-C6H6 metal beta-thioketoiminate complexes were characterized by NMR and in the solid state using single crystal X-ray diffraction techniques. Structural studies reveal that incorporation of a thio-group induces substantial bond angle distortion within the metallocycle. The reactivity of the cationic eta6-C6H6 Ru(II) beta-thioketoiminate complexes toward alkynes and isonitriles is analogous to that of the beta-diketiminate species. Specifically, the reaction with 1-hexyne results in a [4 + 2] cycloaddition involving the metal and beta-C sites, while reaction with isonitrile completely displaces the eta6-C6H6 ligand. A comprehensive DFT study employing charge decomposition analysis (CDA) reveals a strong covalent metal-sulfur bond which dominates the metal beta-thioketoiminate interaction. The M-S bond (M = Ru or Os) is strengthened by charge transfer from metal to sulfur, in contrast to the beta-diketiminate species where back electron donation from the metal to the nitrogen centers is negligible. The first reported beta-selenoketoiminate was prepared by reacting a beta-ketoiminate with the Woolins’ reagent. However, this seleno-analog demonstrated significant instability with respect to hydrolysis, and coordination to an eta6-arene Ru(II) or Os(II) moiety proved unsuccessful.
