, which are 2.1-11.4 times higher than those of recently reported photocatalysts. Our findings reveal that the conjugated structure of TFBE, together with the extended π delocalization within the three-dimensional porous framework formed via C═N cross-linking, effectively promotes the separation of photogenerated electron-hole pairs, thereby enhancing the photocatalytic activity. This work provides fundamental insights into modulating delocalized π electrons to improve the photocatalytic performance.
