Modular Covalent Graphene Functionalization with C<sub>60</sub>
and the Endohedral Fullerene Sc<sub>3</sub>
N@C<sub>80</sub>
: A Facile Entry to Synthetic-Carbon-Allotrope Hybrids
Two novel graphene‐fullerenehybrid structures, containing C60 and endohedral Sc3N@C80 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,
通过还原活化/剥落方法,从原始石墨开始有效地合成了两个新颖的石墨烯-富勒烯杂化结构,其中包含C 60和结合到石墨烯的内面Sc 3 N @ C 80,而不是以前使用的氧化石墨烯。这些多功能混合系统的结构明确地通过统计拉曼光谱,TG-MS,TG-GC-MS和LD-TOF质谱进行了明确表征,从而证实了各自的C 60 / Sc 3 N @ C 80的共价键合原始石墨烯的部分。此外,在依赖温度的拉曼光谱研究的辅助下,还研究了相应的去官能化过程。最后,基于碳60 / Sc 3 N @ C 80与石墨烯偶联的碳同素异形体杂化材料的形成可以通过HRTEM观察。
