Anisotropicexpansion of a spherical M2L4 coordination capsule through the elongation of the ligand led to a new M2L′4 capsule. The expanded capsule provides an elliptical cavity encircled by polyaromatic frameworks with large openings and thereby can encapsulate elliptical fullerene C70 and monofunctionalized fullerene C60 in high yields. In addition, selective formation of a new M2L2L′2 capsule occurs
通过配体的伸长,球形M 2 L 4配位胶囊的各向异性膨胀导致了新的M 2 L' 4胶囊。膨胀的胶囊提供了一个椭圆形腔,该椭圆形腔被具有大开口的聚芳构架包围,因此可以高产率地包封椭圆形富勒烯C 70和单官能化富勒烯C 60。另外,通过在加入C时以1:1的比例混合原始的M 2 L 4和膨胀的M 2 L' 4胶囊,选择性地形成了新的M 2 L 2 L' 2胶囊。60或单官能化C 60作为模板分子。
