尽管内面体富勒烯在基础和应用研究中具有重要意义，但其制备一直依赖于难以控制的物理方法。我们报道了一个四步有机反应，它完全关闭了一个开笼富勒烯的13个成员的环孔。该工艺可用于合成包覆分子氢的富勒烯C-60，可作为纯产物分离出来。这种分子外科方法应该使制备一系列C-60富勒烯成为可能，这些富勒烯要么包裹着小原子，要么包裹着分子，这是传统物理方法无法获得的。
In spite of their importance in fundamental and applied studies, the preparation of endohedral fullerenes has relied on difficult-to-control physical methods. We report a four-step organic reaction that completely closes a 13-membered ring orifice of an open-cage fullerene. This process can be used to synthesize a fullerene C-60 encapsulating molecular hydrogen, which can be isolated as a pure product. This molecular surgical method should make possible the preparation of a series of C-60 fullerenes, encapsulating either small atoms or molecules, that are not accessible by conventional physical methods.
