摘要： 共价有机框架(Covalent Organic Frameworks，COFs)是一类新型晶态多孔聚合物，因其化学结构可设计、孔隙率可调、密度低、比表面积高、稳定性好和功能多样性等特质，在光电器件、能源存储、催化、环境、分离等领域具有广泛的潜在应用前景。为实现这些应用，需理清COFs结构与性能之间的内在关联，而这需要实现COFs单晶的可控制备。本实验结合了作者近期的科研成果，将COFs这一前沿研究领域引入本科教学实验中，实验内容包括COFs单晶的可控制备及结构和性能表征；实验技能除包含常规化学技能操作外，还包括大型仪器的学习及操作。

Abstract: Covalent Organic Frameworks (COFs) are a novel class of crystalline porous polymers that exhibit great potential in fields such as electronics, optoelectronics, energy storage, catalysis, environmental applications, and separation processes. Their remarkable properties, including tunable chemical structures, adjustable porosity, low density, high specific surface area, excellent stability, and diverse functional characteristics, make them promising materials. To realize these applications, it is essential to establish clear correlations between COFs’ structures and properties, which requires the controlled synthesis of COF single crystals. This experiment integrates the authors’ recent scientific findings and introduces the cutting-edge field of COFs into undergraduate laboratory courses. The experimental content covers the controlled synthesis of COF single crystals, as well as their structural and property characterization. In addition to standard chemical techniques, students will also acquire hands-on experience with large-scale instruments.
