To date, covalent organic framework (COF) photocatalytic heterojunctions mainly rely on their crystal outer surface as an interface, while overlooking the extensive surface area provided by internal pore walls. Here, we report a COF pore wall\u2010based heterojunction design achieved by in situ confinement of linear conjugated polymers (LCPs) within COF pores via concurrent growth in copolymerization of a four\u2010aldehyde\u2010functionalized pyrene monomer, a two\u2010amine\u2010functionalized benzene monomer, and a two\u2010aldehyde\u2010functionalized benzothiadiazole monomer. The optimized COF\/LCP hybrid displays enhanced charge carrier generation, lifetime, and transport, resulting in a significant improvement in photocatalytic H\n                    <jats:sub>2<\/jats:sub>\n                    O\n                    <jats:sub>2<\/jats:sub>\n                    production performance (209%\u2010enhancement vs. COF, 75%\u2010enhancement vs. LCP, and 99%\u2010enhancement vs. COF\/LCP physical mixture). The established heterojunction has been proven to efficiently promote electron transfer from COF to LCP, thereby opening new avenues in high\u2010performance photocatalyst design.\n                  <\/jats:p>","DOI":"10.1002\/smll.73617","type":"journal-article","created":{"date-parts":[[2026,5,1]],"date-time":"2026-05-01T08:49:45Z","timestamp":1777625385000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["An Intimate Heterojunction Architecture: Linear Conjugated Polymer Confinement Within Covalent Organic Framework Pores for Enhanced Photocatalytic Hydrogen Peroxide Production"],"prefix":"10.1002","volume":"22","author":[{"ORCID":"https:\/\/orcid.org\/0009-0009-9858-1352","authenticated-orcid":false,"given":"Muhammad Haseeb","family":"Raza","sequence":"first","affiliation":[{"name":"State Key Laboratory of Fluorine and Nitrogen Chemistry and Advanced Materials Shanghai Institute of Organic Chemistry University of Chinese Academy of Sciences Chinese Academy of Sciences  Shanghai P.
