石墨烯的共价功能化是纳米材料领域的一个重要课题。石墨的还原剥离与相应石墨烯中间体的伴随官能化提供了朝向官能化石墨烯衍生物的有前途的方法。在这篇文章中，我们提出了新的见解还原芳基化的石墨烯。具有不同化学计量的石墨插层化合物（GIC）已被用作起始材料。基于扫描拉曼显微镜和热重-质谱联用分析（TG/MS）获得的光谱数据，可以发现GIC中存在的负电荷的量与最终产物中的官能化程度之间存在明显的相关性。
The covalent functionalization of graphene represents a main topic in the growing field of nano materials. The reductive exfoliation of graphite with concomitant functionalization of the respective graphenide intermediates provides a promising approach towards functional graphene derivatives. In this article, we present new insights into the reductive arylation of graphene. Graphite intercalation compounds (GICs) with varying stoichiometries have been used as starting materials. Based on the spectroscopic data obtained by scanning Raman microscopy and thermogravimetric analysis coupled to mass spectrometry (TG/MS), a clear correlation between the amount of negative charges – present in the GIC – and the degree of functionalization in the final product could be found. Furthermore, the detailed analysis of the thermal defunctionalization process provided deeper insights into the covalent addend binding.
