Infrared spectroscopy of all-carbon poly[60]fullerene polymer and [60]fullerene dimer model

All-carbon poly[60]fullerene polymer was prepared in bulk quantity by using a solution-based method. The polymer is free from monomeric and dimeric [60]fullerene species, which allows an infrared spectroscopic study in an unambiguous fashion. The [60]fullerene dimer prepared according to a recently reported mechanochemical method was used as a structural model for the poly[60]fullerene polymer. A systematic comparison between the infrared spectra of the poly[60]fullerene polymer, [60]fullerene dimer and [60]fullerene is reported and discussed.
