Abstract Porous organic polymers (POPs) are emerging as up‐and‐coming photocatalysts for energy conversion, and environmental treatment. However, attention to simultaneously improving photoinduced charge separation, transfer, interfacial reaction is markedly lagged. Herein, the strategy of coupling ionic polarization, electron sponge effect enhancing built‐in electric field (BIEF), surface mass transfer process POPs proposed, which can be realized by a one‐pot post‐pyridiniumnation, Friedel‐Craft reaction. This method endows polarization elevating BIEF boosting separation/migration. The pyridiniumnation not only induces allow shallow trap free electrons but also effectively reduces oxygen adsorption energy, pertinent intermediates, thus leading stronger in 2.73‐fold neutral polymer strengthened O 2 activation. Additionally, photothermal performance with up 15 °C increment contributes enhancement photocatalysis. Consequently, iBPyP‐33 exhibits an unprecedentedly efficient photodegradation 100 ppm bisphenol A (BPA) just 20 min, photosynthesis H rate 3070 µmol g −1 h air, 6583 aided sodium ethylenediaminetetraacetic acid. study provides fresh, valuable insights into design high efficiency.
