Abstract
Covalent functionalization of pristine graphene poses considerable challenges due to the lack of reactive functional groups. Herein, we report a simple and general method to covalently functionalize pristine graphene with well-defined chemical functionalities. It is a solution-based process where solvent-exfoliated graphene was treated with perfluorophenylazide (PFPA) by photochemical or thermal activation. Graphene with well-defined functionalities was synthesized, and the resulting materials were soluble in organic solvents or water depending on the nature of the functional group on PFPA.
摘要
由于缺乏反应活性基团，对原始石墨烯进行共价功能化仍然存在很大的挑战。在此，我们报告了一种简单通用的方法，通过光化学或热激活，用全氟苯叠氮化物（PFPA）对原始石墨烯进行共价功能化。合成了具有明确功能的石墨烯，所得材料根据 PFPA 上的功能团的性质，可溶于有机溶剂或水中。
