Modulating heterocyclic linkages of covalent organic frameworks to expand photocatalytic uranium extraction

Heterocyclic-linked covalent organic frameworks (COFs) integrate organic units into extended structures, offering enhanced π-conjugation, stability, light absorption, and charge separation. Leveraging these properties, this perspective explores COF design for photocatalytic uranium extraction, highlighting the design strategy, photocatalytic performance, and future challenges. It guides the development of photocatalytic uranium extraction, promoting both environmental remediation and the security of nuclear fuel supply.
