일반 설명
4-Oxo-TEMPO is formed by the reaction of 2,2,6,6-tetramethyl-4-piperidone (4-oxo-TMP) and 1O2. It is a stable paramagnetic product formed during the irradiation of TiO2 in aqueous suspensions.
애플리케이션
4-Oxo-TEMPO was employed as nitroxide standard to investigate the generation of singlet oxygen by photoexcited TiO2 in ethanol by ESR spectroscopy. It may be employed as free radical polarizing agent in dynamic nuclear polarization (DNP) studies.
Free-radical nitroxide spin probe typically used for:
- Redox sources for anodes in lithium secondary batteries
- Free-radical biological studies
- Radical spin-trapping
- Electron paramagnetic resonance studies
- Polymer chemisty and synthesis applications

Nitroxides, unlike trityl radicals, have shorter T(2)s which until now were not detectable in vivo by a time-domain pulsed Electron Paramagnetic Resonance (EPR) spectrometer at 300 MHz since their phase memory times were shorter than the spectrometer recovery times. In

In rapid scan EPR the magnetic field is scanned through the signal in a time that is short relative to electron spin relaxation times. Previously it was shown that the slow-scan lineshape could be recovered from triangular rapid scans by

The concept of "oxidative stress" has become a mainstay in the field of neurodegeneration but has failed to differentiate critical events from epiphenomena and sequalae. Furthermore, the translation of current concepts of neurodegenerative mechanisms into effective therapeutics for neurodegenerative diseases

Bimolecular collisions between perdeuterated 2,2,6,6-tetramethyl-4-oxopiperidine-l-oxyl molecules in three alkanes have been studied by measuring the electron paramagnetic resonance (EPR) spectral changes induced by spin exchange. We define an "encounter" to be a first-time collision followed by a series of re-encounters
