High-yield production of highly conductive graphene via reversible covalent chemistry†
Abstract
On the basis of the Diels–Alder reaction of graphite and tetracyanoethylene, graphite has been mechanically exfoliated into graphene adducts in a yield up to 38%. The graphene adduct can restore its conjugated structure via retro-Diels–Alder reaction under mild conditions, exhibiting a high conductivity of 1035 S m−1.
