The ease by which graphene is affected through contact with other materials is one of its unique features and defines an integral part of its potential for applications. Here it will be demonstrated that the substrate of epitaxial graphene itself as well as intercalation layers, created by the insertion of atomic layers under its backside, are efficient tools to change the properties and the interaction of graphene with the environment on its frontside. This enables us to functionalize graphene as a template for patterned adsorption of atoms and molecules resulting e.g. in cluster arrays or antidot lattices.
