摘要
Comprehensive Summary Graphene nanoribbons(GNRs),which can be considered as a special type of conjugated polymers,are quasi-one-dimensional graphene cutouts with an opened band gap,revealing great potential as functional materials in optoelectronic,spintronic,and energy-related applications.An effective strategy to modulate the properties of GNRs is doping heteroatoms into theπ-skeleton.Thanks to the bottom-up synthetic approach,a number of heteroatom-doped GNRs with precise structures have been reported,exhibiting intriguing properties.Nevertheless,a comprehensive summary of the progress of this field has remained elusive.In this review,we summarize the history and advances in bottom-up synthesized heteroatom-doped GNRs,including their synthetic routes,electronic properties,and promising applications.We hope to establish the reliable structure–property relationship,and provide guidance for the molecular design of heteroatom-doped GNRs in the future.
