Abstract

Several procedures were used to fluorinate neat samples of C₆₀ and mixtures of C₆₀/₇₀. Both positive and negative ion mass spectrometry showed C₆₀F_X and C₇₀F_Y product mixtures, with X ≤ 48 and Y ≤ 56, representing the highest degree of fullerene substitution recorded by mass spectrometry to date. Small but significant differences are observed in the mass spectra obtained using field desorption, thermal deposition, and laser desorption ionization techniques, indicating facile loss of fluorine from the highly substituted fullerenes. Slow decomposition in C₆F₆ solution was also observed. Infrared and UV-vis absorption spectra of C₆₀F_X are also reported.
