Liquid chromatographic separation of all-carbon molecules C60 and C70 with multi-legged phenyl group bonded silica phases

The separation of C60 and C70 all-carbon compounds has been examined using new multi-legged phenyl group bonded silicas as the stationary phase in liquid chromatography. Two-legged biphenyl bonded silica gave the best separation because this phase offers the most suitable cavity-like structure to retain the C70 molecule, and this provides good separation between C60 and C70.
