In recent years, they have been developed for applications in the field of solar-driven interface evaporation. Therefore, this paper reviews the research progress of organic small molecules based on photothermal interface evaporation systems. The molecular structure characteristics suitable for this system based on the enhanced photothermal conversion mechanism are introduced. Furthermore, three types of evaporation systems constructed using organic small molecules including membrane-based, foam-based, and hydrogel-based systems are analyzed. These systems are further discussed in terms of their potential applications in seawater desalination, wastewater treatment, and water-electricity cogeneration. Finally, the review concludes by summarizing the current developments and highlighting the challenges that must be addressed, which aims to provide references and insights for the design and development of organic small molecule-based interface evaporation systems.展开更多
