Abstract

Isomerically pure endohedral metallofullerene Dy@C82(C 2v) was synthesized by the electric arc method, extracted from the soot with o-dichlorobenzene, isolated from the extract by HPLC, and characterized by mass spectrometry and spectrophotometry. The spectrophotometric titration of a solution of endohedral metallofullerene Dy@C82(C 2v) was conducted with potassium perchlorotriphenylmethide. The concentration of Dy@C82(C 2v) in o-dichlorobenzene was determined, and the molar absorption coefficients for its neutral and anionic forms were calculated (3.0•103 (at 927 nm) and 4.0•103 mol–1 L cm–1 (at 884 nm), respectively.
