基于快速微波辅助阴离子交换反应，建立了多孔材料阳离子共价有机骨架（COF）的新型通道壁工程策略，并用于制备一系列新型COF。由于二氧化碳 (CO2) 和乙酸根阴离子之间的相互作用，所得的 SJTU-COF-AcO 显示出大大增强的二氧化碳容量，高达原始 COF 的 1.7 倍。首次研究了阳离子 COF 中抗衡阴离子对 CO2 容量的影响，这表明我们的通道壁工程策略是调整 COF 性能以获得高 CO2 容量的有前途的方法。 (C) 2019 中国化学会、中国医学科学院药物研究所。由 Elsevier B.V. 出版。保留所有权利。
A novel channel-wall engineering strategy of the porous materials cationic covalent organic frameworks (COFs) is established based on rapid microwave-assisted anion exchange reaction and utilized to prepare a set of new COFs. Due to the interaction between the carbon dioxide (CO2) and the acetate anion, the resulting SJTU-COF-AcO shows greatly enhanced carbon dioxide capacity up to 1.7 times of the pristine COF. The effect of the counter anions to CO2 capacity in the cationic COFs is investigated for the first time, which demonstrates that our channel-wall engineering strategy is a promising way to tailor the property of COFs for high CO2 capacity.
