For La@C82 embedded into the polycarbonate film, an intensive 1H-electron-nuclear double resonance (ENDOR) has been revealed. Since La-EMF does not contain hydrogen atoms, it evidences for the electron spin density on the matrix protons. Furthermore, for the solutions of La-EMF in hexamethylphosphoramide (HMPA), the paramagnetic shift of the 31P NMR signal of bulk solvent molecules has been revealed. These findings testify the partial localization of unpaired electron outside the fullerene cage. The “transparency” of the fullerene shell to the electron spin density may serve the important factor in designing the fullerene-based materials. [ABSTRACT FROM AUTHOR] |
