Porous organic polymers (POPs) are promising candidates for CO₂ capture and conversion, yet the integration of direct air capture (DAC) and in situ conversion presents a fundamental challenge. Here, we report six novel water-dispersible cyclen-based POPs for efficient atmospheric CO₂ capture and photoreduction. The resulting POPs (POP-1~6) exhibit exceptional aqueous-phase CO₂ uptake (264–569 mg/g) with DAC capacities reaching 11–49 mg g⁻¹ d⁻¹. When integrated with an iron porphyrin catalyst (Fe-P) and a ruthenium-based photosensitizer, these POPs enable efficient photocatalytic atmospheric CO₂-to-CO conversion with rates of 1.4–4.5 µmol g⁻¹ h⁻¹ and a yield up to 93% in water. These findings provide valuable insights for the further exploration of POP materials for atmospheric CO₂ capture and photoreduction.
