摘要:

采用室温离子热法合成了一种氟取代的具有五重贯穿金刚石拓扑结构的三维共价有机骨架材料(COFs), 记为JUC-515. 与高温溶剂热法不同的是, 室温离子液体法具有反应温度和压力低、 反应时间短、 操作简单、 无需催化剂和不产生有机蒸汽污染等优势. 制备的材料具有高度结晶性、 较大的孔隙率和良好的CO2选择性吸附性能.

关键词: 共价有机骨架, 多孔材料, 离子液体, 选择性吸附

Abstract:

We report a new kind of three-dimensional(3D) covalent organic frameworks(COFs) synthesized by room temperature ionic liquid method, denoted as JUC-515, with a 5-fold interpenetrated diamond topological network. The main method to synthesize COFs is solvothermal method, which needs not only high temperature and high pressure but also long reaction time, making it hard to synthesize COFs, especially 3D COFs. Room temperature ionic liquid method, which uses room temperature and ordinary pressure as well as shorter reaction time, is easy to be carried out and can be regarded as a green chemistry method. JUC-515 has high crystallinity, large porosity and favorable carbon dioxide selectivity.

Key words: Covalent organic frameworks(COFs), Porous material, Ionic liquid, Selective absorption
