研究了扫描隧道显微镜（STM）针尖电子注入诱导C60、Ce2@C80和Lu2@C76金属富勒烯聚合反应。仅在C60多层膜在Au（111）上观察到C60聚合，而在C60单层膜在Au（111）上未观察到C60聚合。Si（111）-7 × 7上的Ce2@C80金属富勒烯也通过电子注入聚合，但聚合反应活性低于C60。有趣的是，Si（111）-7 × 7上的Lu2@C76金属富勒烯没有显示任何聚合。基于这些STM观察的尖端诱导聚合，键形成的方向和反应性的依赖于富勒烯的种类进行了讨论。
Polymerization of C60, Ce2@C80, and Lu2@C76 metallofullerenes induced by electron injection from a scanning tunneling microscope (STM) tip has been studied. C60 polymerization has been observed only with C60 multilayer on Au(111) and not with C60 monolayer on Au(111). The Ce2@C80 metallofullerene on Si(111)-7 × 7 also polymerizes by electron injection but has less polymerization reactivity than C60. Interestingly, the Lu2@C76 metallofullerene on Si(111)-7 × 7 does not show any polymerization. Based on these STM observations on the tip-induced polymerization, the direction of the bond formation and the dependence of reactivity on the kind of fullerenes are discussed.
