Cover Feature: Olefin‐Linked Covalent Organic Frameworks as Prospective Artificial Platforms for Efficient Photocatalysis (ChemSusChem 12/2025)

The Cover Feature shows how the development of semiconducting materials for photoredox catalysis holds great promise for the sustainable use of solar energy. Covalent organic frameworks (COFs), which are built by linking organic structs into crystalline frameworks, have advantages such as extended π-conjugation, permanent porosity, exceptional chemical stability, light-harvesting and charge-separation abilities. C. Tian, X. Zhu and co-workers (DOI: 10.1002/cssc.202402656) present a Review of recent advances in the development of olefin-linked COFs and their promising potential applications in photocatalysis. Structural design strategies, preparation methods and structure–function relationships in various photoredox reactions are summarized, and challenges and future prospectives are discussed.
