This review provides a comprehensive overview of the recent progress in chromium-containing polyanionic cathode materials for SIBs, emphasizing the multifunctional roles of chromium in enhancing electronic conductivity, stabilizing crystal structures, and enabling high-voltage redox activity.

Therefore, the precise integration of the D and A moieties into the long-range ordered backbone of the COFs accelerates carrier mobilities and reduces the possibility of electron–hole recombination. COFs with a D–A system have made great progress in the related research of photocatalytic applications.

Further, in order to systematically study the photocatalytic performances, a series of D–A COFs with different linkages and electron-donating/withdrawing groups have been synthesized.
