Abstract

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 Ce_2@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.
