Abstract
Efficient Oxygen Reduction In article number 2501603, Jong-Beom Baek and co-workers illustrate the tunable oxygen reduction reaction (ORR) performance of metal-free covalent organic frameworks (COFs) through alkoxy side-chain engineering. The alkoxy-functionalized COFs exhibit enhanced hydrophilicity and optimized pore wall electronic environments, enabling stronger adsorption of water and *OOH intermediates. This study highlights a new strategy to tailor the COF-based electrocatalysts via molecular side-chain modulation.
