摘要：
The reaction of [60]fullerene with bis-o-quinodimethane precursor 3 containing a dibenzo-18-crown-6 moiety provided preferentially trans-4 bisadduct 5a along with a small amount of cis-2 bisadduct 5b. These bisadducts showed different ionophoric properties from each other; 5a exhibited a high complexing ability toward K+ ion, while 5b hardly showed complexation with any alkali metal ions.
