✦ Synopsis

We report experimental evidence for the photopolymerization of C7o films under irradiation with visible or UV fight. The tendency of C7o to dimerize is also confirmed by molecular dynamics calculations which find that the lowest energy dimer configuration contains a four-membered ring between monomers, similar to that calculated for the Ceo dimer or 'bucky dumbeU'. However, the cross section for this phototransformation is found to be considerably smaller than observed for Ceo, and this is attributed to a reduction in the number of reactive double bonds from 30 in Ceo to only 5 in each polar cap of a C7o molecule.
