| 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. |
