Fluorescent carbon dots are a novel type of nanomaterial. Due to their excellent optical properties, they have extensive application prospects in many fields. Studying the formation process and fluorescence mechanism of CDs will assist scientists in understanding the synthesis of CDs and guide more profound applications. Due to their conjugated structures, aromatic compounds have been continuously used to synthesize CDs, with emissions ranging from blue to NIR. There is a lack of a systematic summary of the formation process and fluorescence mechanism of aromatic precursors to form CDs. In this review, the formation process of CDs is first categorized into three main classes according to the precursor types of aromatic compounds: amines, phenols, and polycyclics. And then, the fluorescence mechanism of CDs synthesized from aromatic compounds is summarized. The challenges and prospects are proposed in the last section.

以芳香族化合物为前驱体制备碳点的形成过程和机理：综述

荧光碳点是一种新型纳米材料。由于其优异的光学性能，它们在许多领域具有广泛的应用前景。研究CD的形成过程和荧光机制将有助于科学家了解CD的合成并指导更深刻的应用。由于其共轭结构，芳香族化合物一直被用来合成碳点，其发射范围从蓝色到近红外。目前对于芳香族前驱体形成碳点的形成过程和荧光机制缺乏系统的总结。在这篇综述中，环糊精的形成过程首先根据芳香族化合物的前体类型分为三大类：胺类、酚类和多环类。然后总结了芳香族化合物合成CDs的荧光机理。最后一节提出了挑战和前景。
