Highly efficient synthesis of [60]fullerene oxides by plasma jet

Abstract

Atmospheric pressure nonequilibrium plasma jet has been applied to the synthesis of [60]fullerene oxides (C 60 O n ) for the first time. C 60 O and C 60 O 2 were produced and isolated in high yields up to 44% and 21%, respectively. The structural assignment of C 60 O was confirmed by comparison with the reported spectroscopic data. Theoretical calculations of 13 C NMR chemical shifts for eight isomers of C 60 O 2 were performed and compared with the experimental data to assign the most possible structure for the obtained C 60 O 2 dominantly as an e isomer.
