Abstract
The present invention relates to a segmented graphene nanoribbon, comprising at least two different graphene segments covalently linked to each other, each graphene segment having a monodisperse segment width, wherein the segment width of at least one of said graphene segments is 4 nm or less and to a method for preparing it by polymerizing at least one polycyclic aromatic monomer compound and/or at least one oligo phenylene aromatic hydrocarbon monomer compound to form at least one polymer and by at least partially cyclodehydrogenating the one or more polymer.
