摘要

Nanopatterning and functionalizing of graphene is often required to tune or enhance its unique physical properties. However, complex processes are needed to overcome the chemical incompatibilities between the patterning template, the functional small molecules or nanoparticles, and the underlying graphene. We present a block copolymer (BCP)-based supramolecular thin film as a versatile platform for the generation of periodic patterns of small molecules and ordered assemblies of nanoparticles on top of a graphene substrate without chemical modification of any components. The present approach opens opportunities to readily pattern and functionalize graphene, and to investigate the structure-property correlations of graphene/nanoparticle and graphene/small molecule composite materials.
