Abstract:
We report on the formation of surface structures by photopolymerization of C60 and C70 in isotropic
solutions. The structures show the same periodicity of the interference patterns used for
photopolymerization and behave as diffraction gratings. Mass spectrometry confirmed that the
deposited material contains polymerized fullerenes, while the structure of the deposit was
investigated by atomic force microscopy. We have also shown that these periodic structures are
useful for inducing mesophase orientation.
