碳点 (CD) 是 21 世纪发现的最通用的纳米材料之一。它们具有许多特性，因此在各种应用中具有潜力。尽管对这些新型纳米粒子的关注度越来越高，但广大科学界正在积极探索它们的局限性。最近对 CD 的分馏和组装的研究进一步突破了 CD 的限制，并证明 CD 既是异质级分的混合物，又是组装大型碳基材料的有前途的构建单元。随着 CD 向微观和宏观层面发展，充分理解结构-性质-活性关系对于预测 CD 的未来至关重要。因此，在这个观点中，基于 CD 中反复验证的发现，突出了结构-性质-活性关系。此外，本观点还简要总结了关于 CD 分裂和组装的研究。最终，这些结构-性质-活性关系和可控性对于开发具有各种应用所需特性的 CD 至关重要，尤其是在光化学、电化学、纳米医学和表面化学领域。综上所述，我们认为，从2004年到现在，历史见证了CD的巨大发展，但仍有进一步研究的空间。此外，考虑到许多有吸引力的特性、结构-性质-活性关系以及 CD 的构建块性质，可以从 CD 控制下构建各种感兴趣的碳基材料。

Structure–Property–Activity Relationships in Carbon Dots

Carbon dots (CDs) are one of the most versatile nanomaterials discovered in the 21st century. They possess many properties and thus hold potentials in diverse applications. While an increasing amount of attention has been given to these novel nanoparticles, the broad scientific community is actively engaged in exploring their limits. Recent studies on the fractionalization and assembly of CDs further push the limits beyond just CDs and demonstrate that CDs are both a mixture of heterogeneous fractions and promising building blocks for assembly of large carbon-based materials. With CDs moving forward toward both microscopic and macroscopic levels, a good understanding of the structure–property–activity relationships is essential to forecasting the future of CDs. Hence, in this Perspective, structure–property–activity relationships are highlighted based on the repeatedly verified findings in CDs. In addition, studies on CD fractionalization and assembly are briefly summarized in this Perspective. Eventually, these structure–property–activity relationships and controllability are essential for the development of CDs with desired properties for various applications especially in photochemistry, electrochemistry, nanomedicine, and surface chemistry. In summary, in our opinion, since 2004 until the present, history has witnessed a great development of CDs although there is still some room for more studies. Also, considering many attractive properties, structure–property–activity relationships, and the building block nature of CDs, a variety of carbon-based materials of interest can be constructed from CDs with control. They can help reduce blind trials in the development of carbon-based materials, which is of great significance in materials science, chemistry, and any fields related to the applications.
