CF3-Bis-TEMPO-Vis: New Visible Light Active Bis-Benzimidazolequinone Alkoxyamine
Molbank, 2021 Alkoxyamines of TEMPO usually dissociate thermally at >100 °C; however, room temperature homolysis, activated by visible light, occurs with benzimidazolequinone derivatives.

The Effect of Piperidine Nitroxides on the Properties of Metalloproteins in Human Red Blood Cells
Molecules, 2023 Nitroxides are stable, low molecular-weight radicals containing a nitroxide group that has an unpaired electron. The presence of a nitroxide group determines their redox properties.

Unraveling Charging and Discharging Processes in Organic Radical-Based Electrodes: A Hierarchical Molecular and Quantum Mechanical Approach. [PDF]
ChemSusChemCharge transfer processes are investigated in p‐type organic electrode materials utilizing stable organic radicals incorporated in a conjugated backbone. Molecular dynamics simulations and time‐dependent density functional theory calculations allow us to evaluate charge transfer states as well as the underlying structure–property relationships. Organic

A novel profluorescent dinitroxide for imaging polypropylene degradation [PDF]
, 2008 Free-radical processes underpin the thermo-oxidative degradation of polyolefins. Thus, to extend the lifetime of these polymers, stabilizers are generally added during processing to scavenge the free radicals formed as the polymer degrades.

EPR Study of Spin Labeled Brush Polymers in Organic Solvents [PDF]
, 2011 Spin-labeled polylactide brush polymers were synthesized via ring-opening metathesis polymerization (ROMP), and nitroxide radicals were incorporated at three different locations of brush polymers: the end and the middle of the backbone, and the end of ...
