Organic Polyradicals as Redox Mediators: Effect of Intramolecular Radical Interactions on Their Efficiency
- Information
- 16 February 2021 171 hit(s) Molecular
The spin–spin interactions between unpaired electrons in organic (poly)radicals, especially nitroxides, are largely investigated and are of crucial importance for their applications in areas such as organic magnetism, molecular charge transfer, or multiple spin labeling in structural biology. Recently, 2,2,6,6-tetramethylpiperidinyloxyl and polymers functionalized with nitroxides have been described as successful redox mediators in several electrochemical applications; however, the study of spin–spin interaction effect in such an area is absent. -
Metallacarboranes as Photoredox Catalysts in Water
- Information
- 02 February 2021 270 hit(s) Molecular
Metallacarboranes with the shape of the Greek letter θ, such as [Co(C2B9H11)2]−, were tested, for the first time, as efficient photoredox catalysts in the oxidation of aromatic and aliphatic alcohols in water. Their efficiency is linked to their high solubility in water, their high oxidizing power (Co4+/3+), and their absence of fluorescence on excitation, among others. -
Resistive Switching Observation in a Gallium-Based Liquid Metal/Graphene Junction
- Information
- 22 January 2021 369 hit(s) Molecular
Resistive switching effect is observed for a gallium–indium/gallium oxide/graphene junction. The use of a gallium-based liquid metal (LM) alloy, in this case, the eutectic gallium–indium with its native gallium oxide skin, directly provides the metal top contact and the oxide layer needed to fabricate a memory. -
Stability of radical-functionalized gold surfaces by self-assembly and on-surface chemistry
- Information
- 12 January 2021 266 hit(s) Molecular
We have investigated the radical functionalization of gold surfaces with a derivative of the perchlorotriphenylmethyl (PTM) radical using two methods: by chemisorption from the radical solution and by on-surface chemical derivation from a precursor. -
Electrocatalytic oxidative Z/E isomerization of a stilbene favoured by the presence of an electroactive persistent radical
- Information
- 01 January 2021 332 hit(s) Molecular
A push–pull-functionalized stilbene has been prepared, with an electroactive perchlorotriphenylmethyl (PTM˙) radical and dimethylamine units as electron-withdrawing and -donating moieties, respectively, showing an electrocatalytic redox-induced Z → E isomerization where the open-shell nature of PTM˙ plays a key role in the isomerization ocurrance.
