Replication data of Lotsch group for: "Postsynthetic Transformation of Imine- into Nitrone-Linked Covalent Organic Frameworks for Atmospheric Water Harvesting at Decreased Humidity"

Herein, we report a facile postsynthetic linkage conversion method giving synthetic access to nitrone-linked covalent organic frameworks (COFs) from imine- and amine-linked COFs. The new two-dimensional (2D) nitrone-linked covalent organic frameworks, NO-PI-3-COF and NO-TTI-COF, are obtained with high crystallinity and large surface areas. Nitrone-modified pore channels induce condensation of water vapor at 20% lower humidity compared to their amine- or imine-linked precursor COFs. Thus, the topochemical transformation to nitrone linkages constitutes an attractive approach to postsynthetically fine-tune water adsorption properties in framework materials.

本文报道了一种简便的合成后连接基转换方法，可从亚胺连接与胺连接共价有机框架（covalent organic frameworks, COFs）制备硝酮连接共价有机框架。本研究获得了两种新型二维（2D）硝酮连接共价有机框架：NO-PI-3-COF与NO-TTI-COF，二者均具有高结晶度与大比表面积。相较于胺连接或亚胺连接的前驱体COFs，经硝酮修饰的孔道可在低20%的湿度条件下诱导水蒸气冷凝。因此，向硝酮连接基的拓扑化学转变，为框架材料的水吸附性能提供了一种极具吸引力的合成后精细调控手段。
