Abstract

MALDI FTMS is shown to be a quick and simple method for analyzing fullerene oxides and their dimers that result from the oxidation of fullerenes. Since only very small quantities of material are needed, HPLC fractions are ideally suited for analysis. We demonstrate the use of PPh3 deoxygenation reactions in providing information into the functionality of the oxygen, with a two order of magnitude increase in sensitivity over previously reported HPLC methods. The ability of FTMS to carry out SORI provides further structural information, and MS4 has been successfully carried out on C60O3. A novel fullerene dimer, C120O3, is proposed and initial data from deoxygenation reactions and SORI suggest the structure involves three tetrahydrofuran-like bridges.
