Abstract:
1. A method of production of graphene which comprises treating a combination of a substrate selected from silicon, silicon carbide or a metal and a graphene precursor having the following properties: (a) an aromatic structure that forms the basis of the graphene structure, said aromatic structure being selected from the group consisting of: benzene, naphthalene, pyrene, anthracene, chrysene, coronene, and phenanthrene, or a cyclic or acyclic structures which can be converted to aromatic structures and (b) at least two different types of functional groups that can react with each other to grow the graphene structure by forming additional carbocyclic aromatic structures, wherein the functional group types are selected from the group consisting of carbon-carbon double bonds, carbon-carbon triple bonds, dienes, ketones, and mixtures thereof to convert said precursors to polyphenylene intermediates and then converting said polyphenylene intermediates to graphene.
