The embedment of a C_n-unit into a carbon network constituting fullerene(s) potentially enables a cage-expansion. Herein, we report a C2-insertion into a fullerene orifice in which the mechanism was examined computationally. The C2-embedded open-[60]fullerene possesses an orifice enlarged from an octagon to a decagon, while the inner space was notably expanded as confirmed by the dynamic motion of the incarcerated H₂O molecule.

C2-插入富勒烯孔

将 C _n -单元嵌入构成富勒烯的碳网络中可能会实现笼式膨胀。在此，我们报告了 C2 插入到富勒烯孔中，其中的机制通过计算进行了检查。嵌入 C2 的开放式 [60] 富勒烯具有从八边形扩大到十边形的孔口，而内部空间显着扩大，这由被监禁的 H ₂ O 分子的动态运动所证实。
