Synthesis and Charge Transport Properties of Redox-Active Nitroxide Polyethers with Large Site Density

To maximize the theoretical redox capacity of polymers containing cyclic nitroxides as redox active pendant groups for high density charge storage application, a compact five membered ring with the smallest equivalent weight among the robust cyclic nitroxides was directly bound to a poly(ethylene oxide) chain 2,2,5,5 Tetramethyl 3 oxiranyl-3-pyrrolin 1 oxyl was synthesized and polymerized via anionic coordinated ring-opening polymerization utilizing diethyl zinc/H2O as an initiator The unpaired electron in the monomer survived during the polymerization giving rise to a high density redox polymer with a weight-specific theoretical capacity of 147 mA h/g Cyclic voltammetry of the polymer layer confined at the surface of an electrode revealed a large redox capacity comparable to the theoretical capacity which was ascribed to the efficient swelling and yet insoluble properties of the polyether in electrolyte solutions by virtue of the high molecular weight of >10(5) and adhesive properties allowing immobilization of the layer on the electrode surface The redox capacity also indicated that the ionophoric polyether matrix accommodated electrolyte anions through the polymer/electrolyte interface to neutralize positive charges produced by the oxidation of the neutral radicals at the polymer/electrode interface The diffusion coefficient for the redox gradient driven charge hopping process corresponded to a large second order rate constant in the order of 10(7) M-1 s(-1), which suggested an efficient electron self-exchange reaction throughout the polymer layer due to the large redox site population and hence to the small intersite distance Test cells fabricated with a polymer/carbon fiber composite layer on an aluminum current collector as the cathode and a Li anode sandwiching an electrolyte layer were capable of charging and discharging as a secondary battery with an output voltage near 3 7 V and were durable for more than 10(3) charging discharging cycles without substantial degradation

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. you can also check out more blogs about 1707-03-5. Formula: C12H11O2P.

A lithium solid electrolyte of acrylonitrile copolymer with thiocarbonate moiety and its potential battery application

Researchers study the solid polymer electrolyte (SPE) to raise the safety and capacity of current lithium ion battery technology to a higher level. We opt to work on the polymer host based on acrylonitrile (PAN), since the nitrile group provides an admirable electrochemical stability and a high polarity, which are critical to the polymeric electrolyte. Yet, the nitrile group is also the origin of high glass transition temperature Tg, which requires synthetic effort s to reduce Tg through tuning the SPE composition. The RAFT mediated polymerization technique is employed to decrease the molecular weight and simultaneously incorporate a substantial amount of thiocarbonate moiety in the backbone. The synthesized PAN copolymer, molecular weight similar to 1600 g mol(-1), contains 43.3% (by mole) carbon, 2.1% sulfur, and 8.7% nitrogen. Copolymerization with dodecyl acrylate increases the free volume of host. Substitution of LiFSI for LiTFSI reduces the glass transition temperature effectively since LiFSI is easier to dissociate and more effective in plasticization. The synthesis effort s result in the highest ion conductivity 6.1 x 10(-4) S cm(-1) at room temperature and 1.1 x 10(-3) S cm(-1) at 50 degrees C. This SPE also displays a lithium transference number 0.318, a high stability when interfacing the lithium metal, and tolerates a potential window of 6.0 V. When sandwiched between lithium anode and NMC622 cathode, the cell of SPE reaches 150 mAh g(-1) in charge and discharge. (c) 2020 Elsevier Ltd. All rights reserved.

Spectroscopic calculations, Hirshfeld surface analysis, and molecular docking studies of anticancer 6-(4-Aminophenyl)-4-(4-methoxyphenyl)-2-methoxynicotinonitrile

The title compound 6-(4-Aminophenyl)-4-(4-methoxyphenyl)-2-methoxynicotinonitrile was deliberated by proton nuclear magnetic resonance, ultraviolet-visible, and Fourier transform infrared spectroscopy techniques. The theoretical optimized geometrical parameters (bond lengths, bond angles and dihedral angles), vibrational wavenumbers, and the non-linear optical properties were calculated using the density functional theory with the Becke, 3-parameter, Lee-Yang-Parr functional method. Hirshfeld surface and two-dimensional fingerprint plot analyses have been performed to study the nature of intermolecular interactions within the crystal structure. The ultraviolet-visible spectrum, global chemical reactivity descriptors, the highest occupied molecular orbital and the lowest unoccupied molecular orbital energies in acetonitrile solvent have performed by Time-Dependent Density Functional Theory approach. The molecular electrostatic potential used to predict the reactive sites indicates that the nitrogen atom of the nitrile group is prone to electrophilic attack, and the hydrogen atoms belonging to the amino group to nucleophilic attack. The first-order hyperpolarizability value indicates that the title compound is a useful claimant as non-linear optical material studies. The reduced density gradient function based on electron density provides a simple, clear, and practical method to research non-covalent interactions was investigated. Molecular docking studies of the title compound have been performed, which suggests that the title molecule may act as a potential anticancer agent.

Methylene Blue as a Photosensitizer and Redox Agent: Synthesis of 5-Hydroxy-1H-pyrrol-2(5H)-ones from Furans

A highly efficient and general singlet-oxygen-initiated one-pot transformation of readily accessible furans into 5-hydroxy-1H-pyrrol-2(5H)-ones has been developed. The methodology was extended to the synthesis of other high-value ,-unsaturated -lactams. This useful set of transformations relies not only on the photosensitizing ability of methylene blue, but also on its redox properties: properties that have until now been virtually ignored in a synthetic context.
