碳基量子点（CQD）的发现为荧光生物成像、肿瘤诊断和治疗以及光/电催化提供了机会。然而，现有的“自下而上”方法的综述主要关注CQD的应用，而不是CQD的形成机制，这主要源于CQD合成过程的高度复杂性。在各种合成方法中，以小分子为“构件”，“自下而上”方法的发展促进了CQD的结构设计、光致发光性质的调节和界面性质的控制。另一方面，许多工作已经证明了 CQD 的“构建块”相关属性。在这篇综述中，从最重要的变量之一出发，总结了“构件”的固有特性与 CQD 的光致发光特性之间的关系。选择拓扑、手性和自由基过程作为“构建块”内在属性的描述符。本综述重点从“自下而上”的过程对近期研究成果进行归纳和总结。此外，还提出了一些与之相关的经验规则。

Fabrication of Carbon-Based Quantum Dots via a “Bottom-Up” Approach: Topology, Chirality, and Free Radical Processes in “Building Blocks”

The discovery of carbon-based quantum dots (CQDs) has allowed opportunities for fluorescence bioimaging, tumor diagnosis and treatment, and photo-/electro-catalysis. Nevertheless, in the existing reviews related to the “bottom-up” approaches, attention is mainly paid to the applications of CQDs but not the formation mechanism of CQDs, which mainly derived from the high complexities during the synthesis of CQDs. Among the various synthetic methods, using small molecules as “building blocks”, the development of a “bottom-up” approach has promoted the structural design, modulation of the photoluminescence properties, and control of the interfacial properties of CQDs. On the other hand, many works have demonstrated the “building blocks”-dependent properties of CQDs. In this review, from one of the most important variables, the relationships among intrinsic properties of “building blocks” and photoluminescence properties of CQDs are summarized. The topology, chirality, and free radical process are selected as descriptors for the intrinsic properties of “building blocks”. This review focuses on the induction and summary of recent research results from the “bottom-up” process. Moreover, several empirical rules pertaining thereto are also proposed.
