Abstract

The invention relates to oligophenylene monomers of general formula I, wherein R¹ is H, halogene, —OH, —NH₂, —CN, —NO₂, or a linear or branched, saturated or un-saturated C₁-C₄₀ hydrocarbon residue, which can be substituted 1- to 5-fold with halogene (F, Cl, Br, I), —OH, —NH₂, —CN and/or —NO₂, and wherein one or more CH₂-groups can be replaced by —O—, —S—, —C(O)O—, —O—C(O)—, —C(O)—, —NH— or —NR³—, wherein R³ is an optionally substituted C₁-C₄₀ hydrocarbon residue, or an optionally substituted aryl, al-kylaryl, alkoxyaryl, alkanoyl or aroyl residue; R^2a and R^2b are H, or optionally one or more of the pairs of adjacent R^2a/R^2b is joined to form a single bond in a six-membered carbocycle; m is an integer of from 0 to 3; n is 0 or 1; and X is halogene or trifluoromethylsulfonate, and Y is II; or X is II, and Y is halogene or trifluoromethylsulfonate. The invention further relates to polymeric precursors as well as methods for preparing graphene nanoribbons from the oligophenylene monomers and the polymeric precursors.
