| Abstract
| - The first successful production and chromatographic isolation of dysprosium endohedralmetallofullerenes are reported. A series of 18 endohedral fullerenes have been separatedand isolated having mainly two dysprosium metals engaged in a range of fullerene cagesfrom C80 up to C94. All these newly synthesized metallofullerenes are characterized by LD-TOF mass spectrometry and UV−vis−NIR absorption spectroscopy. Their possible molecularsymmetry, HOMO−LUMO band gap, and electronic structure are discussed in terms of theirabsorption spectra and HPLC elution time. Their separation and isolation procedure bymultistage high-performance liquid chromatography is discussed in detail.
