20090281330 | Nitrons Carrying a Positive Charge and Usable in Trapping Free Radicals, Especially the Superoxide Radical - The present invention involves new nitrons carrying a positive charge, useful in trapping of free radicals and especially the superoxide radical, of general formula: | 11-12-2009 |
20100249386 | DINITROXIDE-TYPE BIRADICAL COMPOUNDS OPTIMIZED FOR DYNAMIC NUCLEAR POLARIZATION (DNP) - The present invention relates to the field of organic chemistry and in particular to organic free radicals used as polarizing agents in the technique of Dynamic Nuclear Polarization (DNP), which involves transferring the polarization of electron spins to the nuclei of a compound whose Nuclear Magnetic Resonance (NMR) is being observed. It concerns dinitroxide-type biradical polarizing agents characterized by a rigid linkage between the nitroxide units that enables optimal orientation and distance to be maintained between the aminoxyl groups of said nitroxide units. This particular structure enables, at low temperatures and high fields, optimal transfer of polarization and optimal enhancement of NMR/MAS signals of the polarized nuclei of the compound studied. | 09-30-2010 |
