摘要

1. graphene nanoribbons precursor containing repeating units of general formula (I) in kotoroyR, are each represents H, halogen, -OH, -ΝΗ, -CN, -ΝOili hydrocarbyl radical having from 1 to 40 carbon atoms and may be linear or branched, saturated or unsaturated and mono- or polysubstituted by halogen (F, Cl, Br, I), OH, -ΝΗ, -CN and / or -ΝΟ, wherein one or more groups SNtakzhe may be replaced by -O- , -S-, -C (O) O-, -O-C (O) -, -C (O) -, -ΝΗ- or -NR-, wherein R represents an optionally substituted C-hydrocarbyl radical, or optionally substituted aryl, alkylaryl, or alkoxyaryl radikal.2. Graphene nanoribbons obtained using graphene nanoribbons tsiklodegidrirovaniya precursor of claim. 1 in solution or on surfaces metallov.3. A process for preparing precursors graphene nanoribbons, Yamamoto coupling reaction comprising monomers of the general formula (II) in kotoroyR, are each represents H, halogen, -OH, -NH, -CN, -ΝOili hydrocarbyl radical having from 1 to 40 carbon atoms and may be linear or branched, saturated or unsaturated and mono- or polysubstituted by halogen (F, Cl, Br, I), OH, -NH, -CN and / or -NO, wherein one or more groups SNtakzhe may be replaced by - O-, -S-, -C (O) O-, -O-C (O) -, -C (O) -, -NH- or -NR-, where R represents an optionally substituted hydrocarbyl-S- radical or an optionally substituted aryl, alkylaryl, or alkoxyaryl radical, X are a halogen or trifluoromethylsulfonate diazoniy.4.
