Unzipping of C60 on the Cu(111) surface can be exploited to obtain a C=C sp2 single layer structure,  typically graphene. The idea is to promote cage opening and rearrangement on the surface by enhancing specific interphase processes thanks to the energy content of the molecules in the supersonic molecular beam. Theorethical simulations (a) show the feasiblity of this new synthetic approach, while experiments with C60 at the highest KE achievable demonstrate (b and c, Micro-Raman and XPS characterizations) the possibility to grow graphene combining the kinetic activation with a moderate annealing, after the deposition of the first molecular layer.
