The effectiveness of these approaches is largely compromised by the harsh conditions, complexity, and alteration of the original structure. Therefore, developing a facile yet effective PSM for modulating COFs' properties without altering the original geometry and/or structure is a challenge. By introducing a phosphazene moiety, ca. hexachlorocyclotriphosphazene (CP), as a donor scaffold, we fabricated a CP-modified triazine-based COF (TDCP COF) with a donor-acceptor (D-A) configuration, via a facile one-step PSM method, and used it for photocatalytic conversion of O₂ into H₂O₂. The resultant TDCP COF with D-A characteristic and substantial intramolecular dipole moment displays a facilitated exciton dissociation and charge transfer. The modified TDCP COF not only provides more favorable adsorption sites for O₂ molecules, but also manipulates the O₂ activation pathways through multiple mechanisms into •O₂^- and singlet oxygen (¹O₂). Benefiting from these features, the TDCP COF exhibited a three times higher H₂O₂ production rate compared to TD.
