Photosensitive magnetism of radicals coupled with carbon nanotubes

The magnetic coupling of spin-bearing moieties is a recurrent problem of molecular magnetism. We present electron spin resonance results showing that carbon nanotubes could serve this purpose. Moreover, the association of nitroxide radicals (TEMPO) with carbon nanotubes, either covalently or non-cov...

Description
Summary:The magnetic coupling of spin-bearing moieties is a recurrent problem of molecular magnetism. We present electron spin resonance results showing that carbon nanotubes could serve this purpose. Moreover, the association of nitroxide radicals (TEMPO) with carbon nanotubes, either covalently or non-covalently, yields a material with slightly photosensitive magnetism. Wrapping a conjugated polymer (PmPV) 1 Poly(m-phenylene-co-2,5-dioctyloxy-p-phenylene-vinylene). M w=20000 g/mol, M w/ M N=2. 1 around the nanotubes increases the observed effect.
