Abstract: Surface magic for fullerenes Fullerenes are readily obtained simply by vaporizing graphite, but chemists would love a more controlled method of production. A step in this direction was the recently reported 11-step synthesis of a polycyclic aromatic precursor, and its subsequent dehydrogenation in the gas phase to C60 — with a yield of only about 1%. Otero et al. now show that when depositing precursors on a platinum surface followed by heating to 750 K, essentially all precursors are transformed into the corresponding fullerene molecules (C60 or the triazafullerene C57N3). This approach might allow the relatively efficient production of unusual fullerenes or derivatives that cannot be obtained through uncontrolled graphite vaporization.
