N. Tagmatarchis et al., Isolation and spectroscopic study of a series of mono- and dierbium endohedral C-82 and C-84 metallofullerenes, J PHYS CH B, 104(47), 2000, pp. 11010-11012
The successful production, isolation and multistage chromatographic separat
ion 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 an
d UV-vis-NIR absorption spectroscopy.
