Chemical functionalization of new carbon-allotropes such as the two dimensional (2D) graphene is of fundamental interest and opens the door to unprecedented materials applications. We will report on the development of efficient functionalization protocols for graphene using both covalent and non-covalent approaches. In particular, the reductive functionalization of graphene allows for the attachment of a variety of functional systems such as porphyrins and fullerenes to the basal plane. A fundamental challenge of graphene functionalization is the spatially resolved covalent patterning of this 2D-system. We will also emphasize our recent success in this direction. We have demonstrated that both masks assisted patterning of graphene and laser writing can be used and even be combined to generate hierarchically ordered multifunctional 2D-architectures. The potential of practical applications is enormous. This includes chemical information storage exemplified by complete write/read/erase cycles. Moreover, we will present our recent on the chemical functionalization of other 2D-materials such as particular black phosphorus and molybdenum disulfide.
