Covalent–Organic Frameworks: Single‐Pore versus Dual‐Pore Bipyridine‐Based Covalent–Organic Frameworks: An Insight into the Heterogeneous Catalytic Activity for Selective CH Functionalization (Small 22/2021)

Transition metal catalyzed carbon—hydrogen functionalization imparts a paradigm shift in the complex target synthesis, including pharmaceutical and material science applications. To establish structure-function-property relationship of covalent organic frameworks, palladium docked dual-pore COFs with controllable bipyridine content exhibit regioselective C—H to C—X (X = Cl, Br, I) and C—O functionalization, and compared with single pore framework. This protocol presented by Shengqian Ma and co-workers (article number 2003970) features high efficiency, remarkable reusability, and recyclability.
