Covalent organic frameworks (COFs) with abundant redox-active sites are promising electrode materials for sodium-ion batteries (SIBs). However, conventional design strategies are often limited by sluggish Na+ transport and low utilization of active sites. Here, we report a pair of 3D COFs (COF-O and COF-H). In COF-O, t...

Developing artificial photosynthesis systems that couple hydrogen peroxide (H2O2) production with organic valorization remains challenging due to rapid carrier recombination. Herein, indazole-linked covalent organic frameworks (COFs) were constructed via Cadogan reductive cyclization of nitro-functionalized imine-linke...

Polymorphism in covalent organic frameworks (COFs) offers a unique platform to decipher structure-property relationships, yet its impact on excited-state dynamics remains unexplored. Herein, we construct two chemically identical but topologically distinct 1D and 2D COF polymorphs to correlate framework architecture wit...
