Covalent organic frameworks (COFs) are an emerging class of porous crystalline polymers with wide range of potential applications. However, the availability of three-dimensional (3D) COFs is still limited, and their synthesis is confined to the high-temperature solvothermal method. Here, we report for the first time a general and simple strategy to produce a series of 3D ionic liquid (IL)-containing COFs (3D-IL-COFs) by using IL as a green solvent. The syntheses are carried out at ambient temperature and pressure accompanied by a high reaction speed (e.g., only three mins for 3D-IL-COF-1), and the IL can be reused without activity loss. Furthermore, the 3D-IL-COFs show impressive performance in the separation of CO/N and CO/CH. This research thus presents a potential pathway to green large-scale industrial production of COFs.
共价有机框架（COFs）是一类新兴的多孔结晶聚合物，具有广泛的潜在应用。然而，三维（3D）COFs 的可用性仍然有限，其合成仅限于高温溶剂热方法。在这里，我们首次报道了一种通用且简单的策略，即使用离子液体（IL）作为绿色溶剂来制备一系列 3D 含离子液体的 COFs（3D-IL-COFs）。该合成在环境温度和压力下进行，反应速度快（例如，3D-IL-COF-1 的反应仅需 3 分钟），并且 IL 可以重复使用而不会失去活性。此外，3D-IL-COFs 在 CO/N 和 CO/CH 的分离中表现出令人印象深刻的性能。因此，这项研究为 COFs 的绿色大规模工业生产提供了一种潜在途径。
