The reaction of [60]fullerene with a dimethylsulfonium alpha -formylalkylid
e gave a novel methano[60]fullerene having a formyl group at the bridge-hea
d carbon, This 2.2-[60]fulleroalkanal was readily converted into a variety
of N-aryl-2,2-[60]fulleroaldimines by condensation with aromatic amines: on
e of them showed efficient quenching of the fluorescence of the [60]fullere
ne core, due to a photoinduced intramolecular electron transfer. (C) 2001 E
