Abstract :
Metallofullerenes encapsulating Ho and Tm atoms were isolated by using the HPLC method with two different columns. Three isomers of HoTm@C82 and five isomers of Tm2@C82 were identified. The UV–VIS–NIR absorption spectra of these isomer species were similar to those of the corresponding isomers of Er2@C82. This suggests that the cages of HoTm@C82 and Tm2@C82 have the same charge as that of Er2@C82 and that Tm takes the trivalent state in HoTm@C82 and Tm2@C82, contrary to the divalent state in Tm@C82.
