Covalent organic frameworks (COFs) are a class of highly efficient photocatalytic semiconductor materials, which have been developed for the design photoactive nanozymes. Nitrogen (N)-heterocycles could effectively improve their activity COFs. However, systematic exploration nanozymes based on N-containing COFs is still lacking. In this work, series Schiff-base linkages designed and synthesized to explore high-performance addition, Fe ions introduced through post-modification COFs, can not only extend band-edge absorption red-light region thereby broaden its biological applications, but also introduce single site enrich types free radicals in catalytic products. The activities systematically studied, mechanisms uncovered. Interestingly, it as commonly recognized that more content N, better photocatalysis or construction nanozyme. Furthermore, selected used antibacterial showed good against Escherichia coli.
