Anchoring Triple Polar Sites in COFs to Tailor Electronic and Surface Properties for High Optoelectronic Performance
Jilin University · Community Frameworks · +4 more institutions
Abstract
Covalent organic frameworks (COFs) have attracted increasing attention as photocatalysts for hydrogen peroxide (H2O2) production owing to their structural tunability and intrinsic optoelectronic properties. However, achieving efficient charge separation and optimizing surface catalytic sites remain key challenges. Here, we report a rationally designed COF featuring triple polar sites─cyano modification on the vinyl linkage, a triazine center, and electron-donating/withdrawing side groups─that synergistically modulate the electronic structure, reducing exciton binding energy and enhancing charge carrier separation and transfer. Concurrently, the incorporation of methoxy groups tailors the hydrophilic surface…
