The precise generation and harnessing of carbon magnetism at the single-molecule level have been captivating areas of research in chemistry and nanotechnology. However, the realization of magnetic nanographenes, also known as single-molecule π-magnets, through solution-based synthesis has proven challenging because of their high reactivity and insolubility tendency. Recent advancements in on-surface chemistry and scanning probe techniques have significantly propelled the fabrication of carbon-based magnetic nanostructures to offer a rich platform to probe quantum π-magnetism at the single-molecule level. Atomic manipulation, also referred to as probe chemistry, stands as an exciting and essential approach in the toolbox of on-surface chemistry. This approach enables site-selective chemical reactions, thereby allowing for the atomically precise imprinting and tailoring π-magnetism in a variety of nanographenes. This review highlights the recent achievements in the precise synthesis of single-molecule π-magnets using atomic manipulation. Furthermore, we also provide an outlook on the future of probe chemistry in the fabrication of this intriguing class of magnetic nanographenes, featuring designer quantum magnetism.
在单分子水平上精确产生和利用碳磁性一直是化学和纳米技术中引人入胜的研究领域。然而，通过溶液合成实现磁性纳米石墨烯（也称为单分子π磁体）已被证明具有挑战性，因为它们具有高反应性和不溶性倾向。表面化学和扫描探针技术的最新进展显著推动了碳基磁性纳米结构的制造，为在单分子水平上探测量子π磁性提供了一个丰富的平台。原子操纵，也称为探针化学，是表面化学工具箱中一种令人兴奋且必不可少的方法。这种方法能够实现位点选择性化学反应，从而允许在各种纳米石墨烯中进行原子精确的π磁性印记和定制。本综述重点介绍了利用原子操纵精确合成单分子π磁体的最新成果。此外，我们还展望了探针化学在制造这类具有设计量子磁性的有趣磁性纳米石墨烯方面的未来。
