Influence of immobilising anions on the redox switching of polyaniline

J. Chem. Soc., Faraday Trans., 1994
The immobilisation of heteropolyacids into polyaniline films has been studied using the probe beam deflection technique, X-ray photoelectron spectroscopy and scanning electron microscopy. The results indicate that the heteropolyanions modify the redox behaviour and morphology of polyaniline.

The Redox Journey of Iconic Ferrocene: Ferrocenium Dications and Ferrocenate Anions

Angewandte Chemie International Edition, 2021
The recent discoveries of both dicationic and monoanionic ferrocene derivatives throw light on the effect of the substituents on the C5 ring as well as the choice of redox agents and solvent system in the preparation of previously believed to be difficult synthetic targets.

Reversible Electrochemical Anionic Redox in Rechargeable Multivalent-Ion Batteries

Journal of the American Chemical Society, 2023
Rechargeable multivalent-ion batteries are of significant interest due to the high specific capacities and earth abundance of their metal anodes, though few cathode materials permit multivalent ions to electrochemically intercalate within them.

Anionic redox activation of butadiene‐styrene copolymerization

Journal of Polymer Science, 1948
AbstractA redox‐activated emulsion polymerization system has been developed in which benzoyl peroxide, sorbose and ferrous ammonium sulfate constitute the oxidation reduction system. Very rapid rates of reaction were obtained which permitted the use of lower polymerization temperatures. Redox polymers made at 10°C.

Joint Cationic and Anionic Redox Chemistry for Advanced Mg Batteries

Nano Letters, 2020
Lack of appropriate cathodes severely restrains the development of high-energy Mg batteries. In this work, we proposed joint cationic and anionic redox chemistry of transition-metal (TM) sulfides as the most promising way out. A series of solid-solution pyrite FexCo1-xS2 (0 ≤ x ≤ 1) was specially designed, in which S 3p electrons pour into the d bands ...

Entropic Design of Anionic Site to Improve Anionic Redox Stability in Lithium‐Rich Cathode

Advanced Materials
AbstractCobalt‐free manganese‐rich layered oxide is considered one of the most promising cathode materials for next‐generation lithium‐ion batteries due to its high capacity and low cost. However, irreversible anionic redox (OAR) leads to serious failure problems and hinders its wide application. To solve the above problems, the entropy design strategy

A Cobalt Metallacrown Anion Host with Guest‐Dependent Redox Activity

Chemistry – A European Journal, 2009
AbstractTwo bowl‐shaped cavities, each having three OH− hydrogen‐bond donors at its base, are present in double‐cone‐shaped metallacrown anion host [Co6(μ‐OH)6(μ‐L)6]m+ (1m+; HL=3{5}‐(pyrid‐2‐yl)‐5{3}‐(tert‐butyl)pyrazole). Depending on its affinity for the anions present, it can be isolated in its CoIII3CoII3 (m=3; e.g., 1(ClO4)3) and CoIII2CoII4 (m=2;

Anionic Redox Chemistry in Polysulfide Electrode Materials for Rechargeable Batteries

ChemSusChem, 2017
AbstractClassical Li‐ion battery technology is based on the insertion of lithium ions into cathode materials involving metal (cationic) redox reactions. However, this vision is now being reconsidered, as many new‐generation electrode materials with enhanced reversible capacities operate through combined cationic and anionic (non‐metal) reversible redox

The Importance of Anions in Redox-Type Chimie Douce

Molecular Crystals and Liquid Crystals Science and Technology. Section A. Molecular Crystals and Liquid Crystals, 1998
Abstract The interplay between d cationic levels and sp anionic band may result in a partial depopulation of the latter. The holes that are created may associate and lead to anionic catenation with a possible cut-off of the top of the sp band. In any case electrons transferred through an intercalation process will be accepted on levels which are ...
