C60 derivatives covalently linked with the nitroxide radical of 2, 2, 6,6- tetramethylpiperidine-l-oxyl have been synthesized by the following new method: C60 reactswith 4-oxo-2. 2, 6, 6-tetramethyl-piperidinyloxyl (4...C60 derivatives covalently linked with the nitroxide radical of 2, 2, 6,6- tetramethylpiperidine-l-oxyl have been synthesized by the following new method: C60 reactswith 4-oxo-2. 2, 6, 6-tetramethyl-piperidinyloxyl (4-oxo-TEMPO) and an amino acid.展开更多
The compounds containing stable nitroxide radicals possess magnetic properties for the free radical have net magnetic moment. Oxidization of the [60]fulleropyrolidine obtained from the reaction of C60 with diketone an...The compounds containing stable nitroxide radicals possess magnetic properties for the free radical have net magnetic moment. Oxidization of the [60]fulleropyrolidine obtained from the reaction of C60 with diketone and 2-aminoisobutyric acid by m-chloroperoxybenzoic acid gives a new nitroxide integrated with C60. The stable nitroxide based on C60 is confirmed to be antiferro-magnetism with quantum design superconducting quantum interference device (SQUID).展开更多
