The synthesis of hyper-cross-linked resins with tunable porosity and polarity remains a challenge. Herein, we employed an interpenetration reaction, Friedel–Crafts reaction, and amination reaction, and we synthesized a series of polar hyper-cross-linked resins. We found that the porosity and polarity of these resins could be effectively tuned by the interpenetrating polymer networks (IPNs) technology and the Friedel–Crafts reaction. These resins possessed moderate Brunauer–Emmett–Teller (BET) surface area and pore volume, decent polarity, and excellent pore structure, endowing them with efficient adsorption toward phenol. Particularly, the adsorption was very fast: 38 min was sufficient to reach equilibrium, suggesting that these polar hyper-cross-linked resins were potential candidates for the adsorptive removal of phenol.
