<p>Carbon clusters, such as C60 and C70 fullerenes are separated by means of a recognition selector having formula (I), wherein R1 is (a), wherein R2 is O, S or NR12 wherein R12 is independently hydrogen or P=O with the proviso that when R12 is P=O, then only one such group is present and all R2's are additionally bonded to R12, R4 is independently O, S or NH, R3 and R5 are each independently hydrogen or lower alkyl, n and o are each independently zero, 1, 2, or 3, p, q, r, s and t are each independently zero or 1, Ar is a monocyclic or ortho-fused polycyclic aromatic moiety having up to 10 carbon atoms, either of which may be unsubstituted or substituted with one or more lower alkyl, NO2, N(R6)3+, CN, COOR¿7?, SO3H, COR8 and OR9 wherein R6, R7, R8 and R9 are each independently hydrogen or lower alkyl; W is H or CH=CH2; and m is 1 to 10.</p> |
