AZAFULLERENE DERIVATIVES, PROCESSES FOR THEIR PREPARATION AND THEIR USE

摘要

The invention relates to fullerene derivatives of the formula I <IMG> ( I ) where the symbols and indices have the following meanings: F: a fullerene radical of the formula C20+2m where m = 2 to 100; X: C=O, SO2, SO, P(O)R, P(S)R or PR; R: a straight-chain or branched C1-C20-alkyl group, a C6-C14-aryl-C1-C10-alkyl group or a C6-C14-aryl group, where in the alkyl group one or more non-adjacent CH2 groups can be replaced by -C -S-, -COO-, -SiR2- and/or -CO-, alkyl and aryl can, independently of one another, be monosubstituted or polysubstituted by identical or different groups OH, OR1, COOR, OCOR, F, Cl, Br, NO2, CN, NHCOR1 or NR1COR1 and aryl can be substituted by R1 where R1 is a C1-C6-alkyl group; n: a natural number from 1 to 10+m where m = 2 to 100; and also fullerenoxazoles which are obtained, for example, by rearrangement of the fullerene derivatives of the formula I; processes for their preparation and their use.
