Reaction mechanism for the photopolymerization of solid fullerene C60

Abstract A photochemical “2+2 cycloaddition” reaction is proposed to drive the photopolymerization of pristine solid C 60 . This mechanism proceeds via the triplet T 1 state and exhibits a temperature threshold near 250 K, close to the orientational ordering transition of solid C 60 . Below this threshold, the topochemical requirement of reactive double bond alignment on adjacent C 60 molecules becomes improbable, thereby suppressing the reaction rate.
