Optical Properties of Some New Fulleroids and Fullerene Polymers
Optical absorption and luminescence spectroscopy are performed on a number of new fulleroids with the aim of investigating the change in electronic properties as various functional groups are bonded to the molecule. The compounds studied include phenyl-, p-methylphenyl- and p- chlorophenyl fulleroids, as well as compounds produced by chemical and photo-polymerization. The bonding of additional groups appears to give rise to allowed transitions in the visible and U.V. Chemical or photo “polymerization” of C60 gives rise to an insoluble insulator with new absorption peaks and luminescence in the visible and UV, indicative of breaking of icosahedral symmetry.
