文摘

Oxygenated fullerenes anions were produced by a vaporization source equipped with a corona discharge ionizer in the presence of a trace amount of oxygen. In situ mass analysis revealed that the species formulated as C₆₀O_n⁻ (n≤30) were formed in the source and that the degree of oxygenation could be altered by the discharge current. Formation of the epoxide structure in the C₆₀O_n⁻ was suggested by XPS measurements for thin films prepared by deposition of the C₆₀O_n⁻ beam. The structures and formation processes of higher analogues (C₆₀)_mO_n⁻ (m=2,3) are briefly discussed.
