Abstract

The first successful production and chromatographic isolation of erbium endohedral metallofullerenes are reported. A series of 21 different erbium endohedral metallofullerenes, having one, two, and three erbium metal atoms encapsulated in a range of higher fullerene cages, has been separated and isolated. All these newly synthesized metallofullerenes are characterized by LD-TOF mass spectrometry and UV-vis-NIR absorption spectroscopy. Their possible molecular symmetry, HOMO-LUMO band gap, and electronic structure are discussed in terms of their absorption spectra and high-performance liquid chromatography (HPLC) elution time. Their separation and isolation procedure by multistage HPLC is also discussed in detail.
