Synergistic Roles of Hydroxyl Groups and Coordinating Ligands in Governing Metal-Specific Electrocatalytic Nitrate Reduction in Covalent Organic Framework

Electrocatalytic nitrate reduction is often framed in terms of metal identity, yet the decisive factor governing reactivity remains the local coordination environment in which that metal is embedded. Here, we demonstrate that a covalent organic framework (COF) can be engineered to encode a hydroxyl–ligand cooperative...

Vinylene-Linked Woven Covalent Organic Frameworks for the Oxygen Reduction Reaction

Woven covalent organic frameworks (woven COFs) represent a rare class of mechanically interlaced crystalline polymers whose synthesis is largely limited by the availability of suitable linkage chemistry. Herein, we report the first example of a vinylene-linked woven covalent organic framework, constructed through a K...

Metal-free redox active covalent organic frameworks for electrocatalytic oxygen reduction reaction

Designing efficient, metal-free covalent organic framework (COF) electrocatalysts is a promising strategy for the oxygen reduction reaction (ORR) due to their structural tunability and stability. Herein, we report two redox-active donor–acceptor COFs, TAPA-DHTD and TTT-DHTD, incorporating a thiophene-based dithiophened...
