Abstract Olefin‐linked covalent organic frameworks (OL‐COFs) show great promise for visible‐light‐driven photocatalysis. Manipulating atomic‐level donor–acceptor interactions in OL‐COFs is key to understanding their exciton effects this system. Here, three are presented with orthorhombic lattice structures, synthesized via Knoevenagel polycondensation reaction of terephthalaldehyde and tetratopic monomers featuring phenyl, benzo[c][1,2,5]oxadiazole, benzo[c][1,2,5]thiadiazole moieties. These feature tunable interactions, making them ideal studying olefin‐linked systems. Comprehensive analyses, including temperature‐dependent photoluminescence spectra, ultrafast spectroscopy, theoretical calculations, reveal that stronger lead reduced binding energy ( E b ), accelerated dissociation, longer‐lived photogenerated charges, thereby enhancing photocatalytic performance. Notably, The TMO‐BDA COF, the lowest , demonstrates superior activity one‐pot sequential transformation excellent catalytic performance gram‐scale reactions, highlighting its potential practical applications. This work provides valuable insights into regulating effect at molecular level OL‐COFs, offering pathways enhance efficiency.
