Abstract Chemical modification of graphene is a promising approach to manipulate its properties for its end applications. Herein we designed a two-step route through chlorination-Grignard reactions to covalently decorate the surface of graphene with adamantane groups. The chemically modified graphene was characterized by Raman spectroscopy, atomic force microscopy, and X-ray photoelectron spectroscopy. Chlorination of graphene occurred rapidly, and the substitution of chlorine atoms on chlorinated graphene by adamantane Grignard reagent afforded adamantane graphene in almost quantitative yield. Adamantane groups were found to be covalently bonded to the graphene carbons. The present two-step procedure may provide an effective and facile route for graphene modification with varieties of organic functional groups. - Graphical abstract: Adamantane groups covalently functionalized graphene is obtained by direct substitution of chlorinated graphene with bromoadamantane Grignard reagent.
