Abstract To address the urgent need for sustainable energy processes, there is a growing demand multifunctional materials that mimic natural photosynthetic enzyme functions, specifically light‐harvesting, efficient photoinduced charge separation, and integration of molecularly defined catalysts, synergistically interacting within these structures. Herein, successful synthesis an innovative Covalent Organic Framework ( COF‐TFPT‐IsoQ ) constructed from optically active triazine (TFPT) isoquinoline units (IsoQ) as building blocks reported. Post‐synthetic incorporation Ru(bda)‐based water oxidation catalyst (WOC) achieved through IsoQ moieties acting coordinating sites. Leveraging synthetic flexibility designed COF architecture featuring binding sites on its pore walls, various Ru@COF‐TFPT‐IsoQ systems at different Ru:COF ratios are synthesized tested in (λ > 400 nm) oxygen evolution reaction (OER) under sacrificial conditions. All demonstrate efficiency photocatalytic OER, with highest turnover number (TON) 9.1 observed system where Ru‐based WOC incorporated every fourth unit cell. This work provides valuable insights into structural catalytic behavior complexes architectures, highlighting potential robust, efficient, synthetically flexible material light‐induced catalysis.
