- Abstract
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. Turn the other face: Catechol‐enriched graphene was post‐functionalized asymmetrically at the interface of a water–chloroform biphasic system (see figure). By using two amines in the produced amphiphilic Janus type graphene, different superstructures can form when it is dispersed in chloroform or water.
