Graphene alkynylation via the Sonogashira C-C cross-coupling

In this research, LiteScope was used for the characterization of graphene and I/V spectroscopic measuring. The successful grafting of alkynyl groups onto graphene via the Sonogashira reaction between fluorographene and terminal alkynes was reported. Theoretical calculations revealed that fluorographene can efficiently bind and oxidize the palladium catalyst on electrophilic sites activated by fluorine atoms. This paves the way towards conductive and mechanically robust 3D covalent networks.
