Discovering and Verifying Elusive Fullerene Cage Isomers:Structures of C2-p~(11)-(C_(74)-D_(3h))(CF3)_(12)and C_2-p~(11)-(C_(78)-D(3h)(5))(CF3)_(12)

摘要

We recently reported the trifluoromethylation of a mixture of sublimable but insoluble and largely unknown fullerenes at 500 °C and the isolation and NMR characterization of single isomers of stable,soluble C_(2n)(CF3)_(12)derivatives for C_(2n)=C_(74)-D_(3h),C_(76)-T_d(2),C_(78)-D_(3h)(5),C_(80)-C_(2v)(5),and C_(82)-C2(3).
