Recent advances in covalent organic frameworks as photocatalysts for organic transformations

Covalent Organic Frameworks (COFs) have garnered significant interest in recent years due to their potential applications in various fields, including photocatalytic organic conversion reaction. This article aims to review the design and synthesis of COFs, as well as the recent research progress in their photocatalytic conversion of organic compounds. In the first section, we discussed the design principles of COFs, including the selection of building blocks and the strategies for constructing well-defined structures with desired properties. The second part explored the application of COFs as photocatalysts in the conversion reactions of 22 organic compounds. This included a discussion on the mechanisms that underpin photocatalytic reactions and the particular varieties of organic transformations that have been realized through the use of COFs as photocatalytic agents. The progress made in enhancing the photocatalytic performance of COFs through structural modification and heterojunction construction will also be discussed. Furthermore, we discussed five challenges in the application of COFs for photocatalytic organic transformations, including the exploration of efficient synthesis methods, the design of Functional COFs and Structural optimization, etc. Overall, this article aims to provide a comprehensive overview of COFs photocatalyst, with a focus on their potential use in the photocatalytic conversion of organics, and finally proposing the challenges they still face. By exploring the design, synthesis, and recent research progress in this area, we hope to shed light on the future directions and potential applications of COFs in sustainable Organic catalysis.
