摘要：

Our current gas phase models of the chemistry of interstellar clouds have been extended to produce molecules as complex as fullerenes. Interstellar fullerenes are formed via an ion/molecule synthesis in which linear carbon chains grow until they spontaneously convert into monocyclic rings, which then undergo condensation reactions to form tricyclic rings. The tricyclic rings are converted to fullerenes by collisional processes which generate sufficient amounts of internal energy to overcome activation energy barriers. To determine the products of individual reactions and photoprocesses, a simplified statistical theory has been invoked.
