南开大学王小野小组综述了杂原子掺杂的石墨烯带的精密合成和新兴属性。相关论文发表在2024年7月30日出版的《中国化学》杂志上。

石墨烯纳米带(GNRs)是一类特殊的共轭聚合物，具有开放带隙的准一维石墨烯切割，在光电、自旋电子和能源相关的功能材料中显示出巨大的潜力。在π骨架中掺杂杂原子是调节GNRs性能的一种有效策略。由于自下而上的合成方法，许多具有精确结构的杂原子掺杂GNR已经被报道，表现出有趣的性质。然而，对这一领域的进展进行全面总结此前并不多见。

在该文中，课题组综述了自下向上合成杂原子掺杂GNR的历史和研究进展，包括合成路线、电子性质和应用前景。团队希望为GNR建立可靠的结构-性能关系，为今后杂原子掺杂GNR的分子设计提供指导。

Abstract: 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 the π-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.
