Provided are graphene nanoribbon precursors comprising repeated units of the general formula (I) in which R1, R2 are each H, halogen, —OH, —NH2, —CN, —NO2 or a hydrocarbyl radical which has 1 to 40 carbon atoms and may be linear or branched, saturated or unsaturated and mono- or poly-substituted by halogen (F, Cl, Br, I), —OH, —NH2, —CN, and/or —NO2, where one or more CH2 groups may also be replaced by —O—, —S—, —C(O)O—, —O—C(O)—, —C(O)—, —NH— or —NR—, in which R is an optionally substituted C1C40-hydrocarbyl radical, or an optionally substituted aryl, alkylaryl or alkoxyaryl radical.
提供的是石墨烯纳米带前体,其包含通式(I)的重复单元,其中R1、R2分别为H、卤素、—OH、—NH2、—CN、—NO2或具有1至40个碳原子的烃基基团,可以是直链或支链、饱和或不饱和,并且可以被卤素(F、Cl、Br、I)、—OH、—NH2、—CN和/或—NO2单宁或多宁取代,其中一个或多个CH2基团也可以被—O—、—S—、—C(O)O—、—O—C(O)—、—C(O)—、—NH—或—NR—取代,在其中R是一个可选的取代C1C40烃基基团,或一个可选的取代芳基、烷基芳基或烷氧基芳基基团。
