A covalently linked graphene-oligo(phenylenevinylene) adduct: self-organization and photo-physical properties

Author affiliations

Abstract

We report a simple method of covalent functionalization of graphene with an organic donor such as oligo(phenylenevinylene) (OPV). We present morphological proof for the unprecedented self-organization of these hybrids into higher order assemblies, with a periodic spacing of ∼2.3 nm, intercalated with OPV molecules. After systematic characterization of the resulting hybrid material, we provide unequivocal proof for possible electronic communication between the donor OPV molecules and the graphene sheets. The extent of functionalization and degree of fluorescence quenching were determined by hydrolyzing the EG-OPV hybrid. We also discuss the formation of head-to-tail cyclo-addition dimer of OPV molecules possibly due to the topochemical constraint set by the assembled EG-OPV.
