了解化学形成机制对于实现有效产量和目标产品至关重要。最具挑战性的工作之一是分子纳米碳的合成。内嵌金属富勒烯因其独特的性质而受到特别关注，在各种应用中都有前景。然而，金属掺杂石墨的形成机制在很大程度上回避了实验研究，因为需要严酷的合成方法才能获得它们。在这里，我们报告了在核心合成条件下自下而上形成单金属富勒烯。电荷转移是指导形成的主要因素，这是通过对元素周期表中几乎所有可用元素的金属富勒烯形成的研究发现的。这些结果可以制定生产策略，克服阻碍金属富勒烯当前和未来应用的长期存在的问题。
An understanding of chemical formation mechanisms is essential to achieve effective yields and targeted products. One of the most challenging endeavors is synthesis of molecular nanocarbon. Endohedral metallofullerenes are of particular interest because of their unique properties that offer promise in a variety of applications. Nevertheless, the mechanism of formation from metal-doped graphite has largely eluded experimental study, because harsh synthetic methods are required to obtain them. Here we report bottom-up formation of mono-metallofullerenes under core synthesis conditions. Charge transfer is a principal factor that guides formation, discovered by study of metallofullerene formation with virtually all available elements of the periodic table. These results could enable production strategies that overcome long-standing problems that hinder current and future applications of metallofullerenes.
