ABSTRACT
In this work, we describe the design, synthesis and characterization of new organometallic complexes anchored onto the surface of graphene by non-covalent interactions. Immobilization is possible due to the p-interactions between aromatic groups (such as pyrene) present in the molecules and the polyaromatic nature of the graphene.[1] Although the p-interactions are considered as “weak”, the multiplicity and the electronic structure of graphene favor a strong interaction between the metal complexes and the material.[2] The process is simple, scalable and preserve the inherent properties of graphene.
The catalytic properties of the homogeneous catalyst and the corresponding hybrid material are evaluated, showing that the latter improve the catalytic outcomes compared to the homogeneous complexes. The immobilization of the molecular complexes onto graphene allows the recovery and reuse of the catalyst.[3]
