Carbon Dioxide Conversion Upgraded by Host-guest Cooperation between Nitrogen-Rich Covalent Organic Framework and Imidazolium-Based Ionic Polymer.

Invited for this month's cover are the groups of Rongjian Sa and Ruihu Wang at Minjiang University and the Chinese Academy of Sciences. The image shows how host-guest composite catalysts with task-specific components for the cycloaddition of CO2 with epoxides have been developed through integrating nitrogen-rich covalent organic framework and imidazolium-based ionic polymer.
