The exploration of cost‐effective and efficient catalysts for the transformation of CO 2 into chemicals at room temperature and low CO 2 pressure is a key challenge. Here, a green synthesis method of porous organic polymer was developed, which was obtained by the Scholl coupling reaction via polycondensation of 1,3,5‐triphenylbenzene and 1,10‐phenanthroline at room temperature. The polymer has a large surface area (1074 m 2 g −1 ) and exhibited excellent CO 2 capture of 77.26 cm 3 g −1 at 273.15 K and 1.00 bar. After loading cobalt acetate, an ultralow Co loading phenanthroline‐based porous organic polymer was obtained with very high catalytic efficiency in TOF of 263 h −1 for the fixation of CO 2 to cyclic carbonates at room temperature and atmospheric with free‐solvent, which is over six‐fold than that of a molecular analogue, 1,10‐phenanthroline‐Co(OAc) 2 . This work provided a facile, powerful, green, and efficient strategy for designing porous organic polymers as high‐efficient heterogeneous catalysts in the fixation of carbon dioxide.
