New hybrid fullerene C60 derivatives with five norbornadiene fragments bound to a fullerene core by several methylene groups were synthesized for the first time. Subsequent photoirradiation of these C60 fullerene derivatives leads to only partial (up to 20%) opening of double bonds in norbornadiene fragments to form quadricyclane substituents. It is assumed that the resulting C60 fullerene derivatives can be the basis to create high-energy materials.
