A tangle of threadlike carbon polymers, which do not form two-dimensional layers, was observed in the transmission electron micrograph of the fullerene black produced in an electric arc. Curved polycyclic layer structures were also formed. Both of the suggested mechanisms for fullerene formation—via small rings, which then condense, or via macrocycles, which then isomerize—thus seem possible. Which of the two dominates depends on the reaction conditions.
