Herein, we propose an electron delocalization strategy via functional group\u2010modified heteroatom doping. Through DFT screening and three\u2010step copolymerization of phytic acid and urea, we precisely synthesized a 4\u2010coordinated OH\u2010bridged P\u2010doped carbon nitride (CN\u2212POH) featuring a unique 2N\u2013P\u2550OOH microstructure within heptazine units.

Experimental and theoretical results reveal that P doping disrupts the \u03c0\u2013\u03c0 conjugation, triggering electron delocalization and transferring electrons to adjacent active N sites. The OH\u2010modified P atom forms 2N\u2013P\u2550OOH coordination, inducing spatial charge polarization between VBM and CBM, which significantly enhances charge separation and electron delocalization. This unique structure also converts CO\n                    <jats:sub>2<\/jats:sub>\n                    adsorption from physical to chemical mode under the effect of water solvents and facilitates CO\n                    <jats:sub>2<\/jats:sub>\n                    \u2010to\u2010CO conversion via hydrogen bonding with the water solvent.
