Research Projects

Based on reticular chemistry, our group has been devoted to the structural design and rational synthesis of covalent organic frameworks. Various novel covalent organic frameworks (COFs) have been prepared with new linkages or topologies. Moreover, we have also developed several new methods for COF preparation.

With large surface areas, developed channels, and highly designable structure, COFs were perfect application platforms. Our group prepared various functional COFs, especially three-dimensional COFs, for applications such as gas storage and separation, heterogeneous catalysis, energy storage and conversion, drug delivery, etc. Both bottom-up (e.g. active linkages, active building blocks, in-situ loading, etc.) and post-functionalization approaches (e.g. covalent modification, metalation, etc.) were utilized for the introduction of active sites.

For practical applications of covalent organic frameworks, we focused on improving the robustness of these materials. The chemical stabilities have been successfully enhanced via robust linkages, steric hindrance and hydrophobic engineering.
