Isolation and spectroscopic study of a series of mono- and dierbium endohedral C-82 and C-84 metallofullerenes
The successful production, isolation and multistage chromatographic separation of the Er@C-82(I, II), Er-2@C-84(I), and Er-2@C-82(I, II, III) isomers are described in detail. The newly synthesized metallofullerenes Er@C-82(I, II) and Er-2@C-84(I) are also characterized by LD-TOF mass spectrometry and UV-vis-NIR absorption spectroscopy.
