ABSTRACT:
Carbon clusters, such as C.sub.60 and C.sub.70 fullerenes are separated by means of a recognition selector having the formula: ##STR1## wherein R.sub.1 is ##STR2## wherein R.sub.2 is O, S or NR.sub.12 wherein R.sub.12 is independently hydrogen or P.dbd.O with the proviso that when R.sub.12 is P.dbd.O, then only one such group is present and all R.sub.2 's are additionally bonded to R.sub.12,
