Two 2-aminomethylpyridine-appended [60]fullerenes (1) with the 5,6-open and the 6,6-closed structure were synthesized in order to examine the influence of the structural difference on the metal-binding ability. Both compounds could form the 1:1 complex with Ag+ but the Kass for 5,6-1 was larger by more than two orders of magnitude than that for 6,6-1.

富勒烯(1),分别具有5,6-开放和6,6-闭合结构,以探讨结构差异对
金属结合能力的影响。这两种化合物均可与Ag+形成1:1的复合物,但5,6-1的结合常数Kass比6,6-1大两个数量级以上。
