  • ORTHO-TERPHENYLS FOR THE PREPARATION OF GRAPHENE NANORIBBONS
    Publication number: 20170081192
    Abstract: The present invention concerns ortho-Terphenyls of general formula (I); wherein R1, R2, R3 and R4 are independently selected from the group consisting of H; CN; NO2; and saturated, unsaturated or aromatic C1-C40 hydrocarbon residues, which can be substituted 1- to 5-fold with F, CI, OH, NH2, CN and/or NO2, and wherein one or more —CH2-groups can be replaced by —O—, —NH—, —S—, —C(?O)O—, —OC(?O)— and/or —C(?O)—; and X and Y are the same or different, and selected from the group consisting of F, CI, Br, I, and OTf (trifluoromethanesulfonate); and their use for the preparation of graphene nanoribbons as well as a process for the preparation of graphene nanoribbons from said ortho-Terphenyls.
