C60Ox, x = 1-3 were prepd. by exposing C60 solns. to ozone. After HPLC purifn., these materials were studied by laser desorption time of flight mass spectroscopy. These mass spectra suggest that fullerene oxides undergo laser desorption induced coalescence more efficiently than pure C60. A correlation between the fragmentation of the desorbed parent species and the obsd. coalescence products both in yield and distribution suggests that efficient gas phase coalescence involves at least 1 reactive species, such as C58, produced by fragmentation of the desorbed fullerenes or fullerene derivs.
