Two-dimensional sp(2)c-conjugated polymers (2D sp(2)c-CPs) refer to layered materials constructed by C=C. 2D sp(2)c-CPs have shown great potential in photocatalytic conversion of high-value-added products, osmotic energy generation, fluorescence sensing, proton conduction, organic semiconductor devices, and the extraction of radioactive nuclides, due to their designable periodic porous structures, high surface area, excellent structural stability, and high charge transfer. This review primarily elucidates the research endeavors of our research group concerning 2D sp(2)c-CPs. Firstly, the structural design and synthesis methods of 2D sp(2)c-CPs are presented. Subsequently, the preparation strategies for 2D sp(2)c-CP films, primarily conducted by our research group are introduced. Moreover, the applications of 2D sp(2)c-CPs in seawater uranium extraction, osmotic energy generation, fluorescence sensing, proton conduction, and photocatalysis are summarized in detail. Finally, the review offers a perspective on the research of 2D sp(2)c-CPs, encompassing modulation of crystal structure, exploration of novel synthesis methods, design of universal film synthesis strategies, and the expansion of related applications.
