Abstract Two novel graphene‐fullerene hybrid structures, containing C 60 and endohedral Sc 3 N@C 80 bound to graphene, instead of the formerly used graphene oxide, were efficiently synthesized via a reductive activation/exfoliation approach starting from pristine graphite. The structures of these multifunctional hybrid systems were unambiguously characterized by statistical Raman spectroscopy, TG‐MS, TG‐GC‐MS, and LD‐TOF mass spectroscopy, confirming the covalent bonding of the respective C 60 /Sc 3 N@C 80 moieties to the pristine graphene. Furthermore, assisted by temperature‐dependent Raman spectroscopy studies the corresponding defunctionalization processes were also investigated. Finally, the formation of a carbon allotrope hybrid material on the basis of C 60 /Sc 3 N@C 80 moieties coupled to graphene could be visualized by HRTEM.
