The interfacial asymmetric post‐functionalization of graphene nanosheets and their self‐assembly into superstructures is presented. By performing two sequential functionalizations, graphene nanosheets lying in the interface of a biphasic aqueous‐organic system become amphiphilic, thereby generating an organophilic side and a hydrophilic side. The as‐prepared Janus type amphiphilic graphene nanosheets are then self‐assembled to generate different interesting superstructures, depending on the nature of the solvent in which they are dispersed.
