摘要：
A solvent effect on the electronic absorption UV-VIS and ESR spectra of La@C82 and Y@C82 was found. The UV-VIS spectra of La@C82 in pyridine, dimethylformamide, and hexamethylphosphorotriamide are identical with that of the La@C82– anion, which is evidence for La@C82 reduction in these solvents. In amino-containing solvents, the shape of the ESR spectra depends on the temperature and the time of preparation of the solutions. Changes in the ESR spectra of La@C82 and Y@C82 in dimethylformamide are due to functionalization of these compounds upon reduction.
