Unprecedented POSS‐linked 3D Covalent Organic Frameworks with scu or sqc Topology Regulated by Porphyrin Center for Photocatalytic CO2 Reduction

The synthesis and characterization of porphyrin center regulated three‐dimensional covalent organic frameworks (COFs) with 2‐fold interpenetrated scu or sqc topology have been investigated. These COFs exhibit unique structural features and properties, making them promising candidates for photocatalytic applications in CO 2 reduction and artemisinin synthesis. The porphyrin center serves as an anchor for metal ions, allowing precise control over structures and functions of the frameworks. Furthermore, the metal coordination within the framework imparts desirable catalytic properties, enabling their potential use in photocatalytic reactions. Overall, these porphyrin center regulated metal‐controlled COFs offer exciting opportunities for the development of advanced materials with tailored functionalities.
