BREAKING THE BOTTLENECK OF COFs

摘要

As an emerging class of crystalline porous materials, covalent organic frameworks (COFs) have received extensive interest for their myriad of potential applications in drug delivery, gas filtration and storage, heterogeneous catalysis, and even removal of toxic pollutants. This broad range of COF applications is enabled by their tunable topology, connectivity, and functionality. However, one of the long-standing bottlenecks in COF synthesis is how to develop new chemistry to simultaneously address the demands for specific topology, robust connectivity, and diversified functionality. Specifically, the integration of functionality and ultra-stability into one COF system has remained an enormous challenge to researchers.
