探索一种温和、清洁、高效、普适的石墨烯量子点合成方法具有重要的意义和重要性。本文介绍了一种新的绿色、快速、通用的石墨烯量子点制备方法--紫外光照射下含氧芳香族化合物的自由基聚合。该方法具有较高的产率（86%），副产物仅为H2O和CO2。所制备的石墨烯量子点结晶良好，具有良好的光学和生物学性能。彩色的、不同尺寸的石墨烯量子点可用于体外和体内的荧光生物成像。该方法不仅适用于石墨烯量子点的制备，也适用于杂原子掺杂石墨烯量子点的制备。
It is of great significance and importance to explore a mild, clean, and highly efficient universal approach for the synthesis of graphene quantum dots. Herein, we introduced a new green, rapid, and universal preparation approach for graphene quantum dots via the free-radical polymerization of oxygen-containing aromatic compounds under ultraviolet irradiation. This approach had a high yield (86%), and the byproducts are only H2O and CO2. The obtained graphene quantum dots were well-crystallized and showed remarkable optical and biological properties. The colorful, different-sized graphene quantum dots can be used in fluorescent bioimaging in vitro and in vivo. This approach is suitable not only for the preparation of graphene quantum dots but also for heteroatom-doped graphene quantum dots.
