However, their synthesis typically relies on post\u2010synthetic modifications to stabilize linkages and introduce chelation sites, and metal incorporation is almost exclusively achieved through post\u2010synthetic chelation of pre\u2010formed COFs. Such approaches often result in compromised crystallinity, incomplete conversion and limited control over modification sites. Here, we report a direct, one\u2010pot nickel\u2010mediated Friedl\u00e4nder annulation strategy to construct Ni\u2010chelated fused heterocycle\u2010linked COFs (\n                    <jats:bold>NNiN<\/jats:bold>\n                    ,\n                    <jats:bold>NNiO,<\/jats:bold>\n                    and\n                    <jats:bold>NNiS<\/jats:bold>\n                    ). The fused heterocycle linkages act as an additional structural regulation factor, enabling precise tuning of framework packing and metal\u2010chelation environment, thereby enhancing crystallinity and optoelectronic properties simultaneously. The resulting COFs exhibit extended \u03c0\u2010conjugation, efficient Ni chelation and strong charge\u2010transfer absorption in the visible\u2010light region. Combining conjugated robust linkages, accessible single\u2010site Ni centers, and self\u2010photosensitizing capability, these frameworks provide a powerful platform for photocatalysis. They achieved up to 98% conversion in carbon\u2010chalcogen coupling reactions, while retaining crystallinity and catalytic activity over multiple cycles. This work thus offers a general strategy for designing stable, \u03c0\u2010conjugated, and metal\u2010functionalized COFs, broadening opportunities for heterogeneous catalysis and beyond.\n                  <\/jats:p>","DOI":"10.1002\/anie.202518983","type":"journal-article","created":{"date-parts":[[2025,11,4]],"date-time":"2025-11-04T07:10:29Z","timestamp":1762240229000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Nickel\u2010Mediated Synthesis of Fused Heterocycle\u2010Linked Covalent Organic Frameworks for Self\u2010Sensitized Photocatalysis"],"prefix":"10.1002","volume":"64","author":[{"given":"Xiaofei","family":"Zhang","sequence":"first","affiliation":[{"name":"Institute of Materials Research and Engineering (IMRE) Agency for Science, Technology and Research (A*STAR)  2 Fusionopolis Way Singapore 138634 Singapore"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yu","family":"Tang","sequence":"additional","affiliation":[{"name":"Department of Chemistry National University of Singapore 3 Science drive 3  Singapore 117543 Singapore"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Caoyu","family":"Yang","sequence":"additional","affiliation":[{"name":"Laboratory of Nanosystem and Hierarchical Fabrication National Center for Nanoscience and Technology  Beijing 100190 P.R.
