Abstract

image

A new strategy to form ordered hierarchical supramolecular gels that incorporate graphene oxide (GO) sheets and cationic rigid macrocyles under mild conditions via self-assembly is demonstrated. These ordered gels are stabilized by a series of non-covalent – donor-acceptor, π–π stacking, cation-π – interactions. These theoretical studies indicate that cationic macrocycles are positioned in between GO layers with a substantial binding energy.
