Paramagnetic C60 derivatives with one and more unpaired electrons: Spin polarization and photoelectron transfer
نویسندگان
چکیده
Fullerene C60 derivatives covalently linked to a nitroxide radical are studied by Time Resolved EPR. The interaction between radical and triplet or singlet excitation, localized on the fullerene moiety, gives rise to spin polarization of the radical EPR signal. The quartet state of the Radical Triplet Pair (RTP) is also observed by EPR. Electron transfer involving the excited fullerene triplet is studied through the effects on the spin polarization pattern.

Electron Paramagnetic Resonance (EPR) spectroscopy, also known as Electron Spin Resonance(ESR) especially among physicists, is a strong and versatile spectroscopic method forinvestigation of paramagnetic systems, i.e. systems like free radicals and most transition metalions, which have unpaired electrons. The sensitivity and selectivity of EPR are notable andintriguing as compared to other spec...

The magnetisation and electron spin resonance (ESR) spectrum of two specimens of tetrahedral amorphous carbon (ta-C), deposited from a filtered cathodic arc, were measured over a wide temperature range. The magnetisation was found to consist of superparamagnetic, paramagnetic and diamagnetic contributions. The superparamagnetic contribution resembled that recently found in carbon prepared from ...

H NMR of two H2@C60 nitroxide derivatives has been characterized indirectly by reducing to their corresponding hydroxylamines. Nuclear spin relaxation of the endohedral H2 and external protons of the H2@C60 nitroxide and its corresponding hydroxylamine were measured and analyzed. The observed spectra are consistent with negligible scalar coupling between the unpaired electron and the endo-H2. A...

The study of inorganic crystalline materials by solid-state NMR spectroscopy is often complicated by the low sensitivity of heavy nuclei. However, these materials often contain or can be prepared with paramagnetic dopants without significantly affecting the structure of the crystalline host. Dynamic nuclear polarization (DNP) is generally capable of enhancing NMR signals by transferring the mag...
