Separation, Detection, and UV/Visible Absorption Spectra of Fullerenes; C76, C78, and C84

Abstract
New kinds of fullerenes were separated by HPLC with benzene from carbon soot. At least four fractions were well separated. Mass analysis confirmed the separation of C60, C70, C84 and the mixture of C76 and C78. Absorption spectra of C76, C78, and C84 were measured for the first time.
