| Abstract: | The development of cost‐effective and environmentally friendly photocatalysts and photosensitizers has received tremendous attention because of their potential utilization in solar‐light‐harvesting applications. In this respect, carbon dots (CDs) prepared by bottom‐up methods have been considered to be promising light‐harvesting materials. Through their preparation from various molecular precursors and synthetic methods, CDs exhibit excellent optical and charge‐transfer properties. Furthermore, their photophysical properties can be readily optimized and enhanced by means of doping, functionalization, and post‐synthetic treatment. In this review, we summarize the recent progress in CDs synthesized using bottom‐up approaches. These CDs exhibit strong light absorption and unique electron donor/acceptor capabilities for light‐harvesting applications. We anticipate that this review will provide new insights into novel types of photosensitizers and photocatalysts for a wide range of applications. |
