Abstract
AbstractTo date, two‐dimensional (2D) β‐ketoenamine‐linked covalent organic frameworks (COFs) have exhibited tremendous potential in visible light photocatalysis due to their broad absorption and favorable stability provided by the linkage. Here, with 1,3,5‐triformylphloroglucinol as the stationary building block, various COFs can be constructed to address different challenges. To inspire state‐of‐the‐art advancements toward photocatalysis, in this Concept article, the rational design of 2D β‐ketoenamine‐linked COFs is summarized. First, the dimension of engineering the linker is considered to improve the activity of the COFs. The photocatalysis could be extended by inserting a functional group to the other building block. Second, the other dimension of integrating cocatalysts like transition metals or 2,2,6,6‐tetramethylpiperidine‐N‐oxyl with β‐ketoenamine‐linked COFs could further expand the potential in photocatalytic reactions. These prior accomplishments establish that the rational design of 2D β‐ketoenamine‐linked COFs is instrumental in improving the photocatalytic activity, laying the foundation for future explorations.
