Abstract

Abstract: A controlled, reproducible, gram‐scale method is reported for the covalent functionalization of graphene sheets by a one‐pot nitrene [2+1] cycloaddition reaction under mild conditions. The reaction between commercially available 2, 4, 6‐trichloro‐1, 3, 5‐triazine and sodium azide with thermally reduced graphene oxide (TRGO) results in defined dichlorotriazine‐functionalized sheets. The different reactivities of the chlorine substituents on the functionalized graphene allow stepwise post‐modification by manipulating the temperature. This new method provides unique access to defined bifunctional 2D nanomaterials, as exemplified by chiral surfaces and multifunctional hybrid architectures. Abstract : A simple and mild method has been developed for the reaction of 2, 4, 6‐trichloro‐1, 3, 5‐triazine and sodium azide with thermally reduced graphene oxide to form defined dichlorotriazine‐functionalized sheets. The different reactivities of the chlorine substituents on the functionalized graphene allow stepwise post‐modification by manipulating the temperature, thus providing unique access to defined bifunctional 2D nanomaterials.
