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.
[60]富勒烯与含有二苯并-18-冠-6部分的双-邻-喹二甲烷前体3的反应优先提供了反式-4双加合物5a以及少量的顺式-2双加合物5b。这些双加合物表现出彼此不同的离子载体性质。5a显示出对K +离子的高络合能力,而5b几乎没有显示出与任何碱金属离子的络合。
