A novel ferrocene‐linked organic–inorganic hybrid porous polymer has been successfully prepared by Friedel–Crafts reaction of octavinylsilsesquioxane and ferrocene. The relationship of structure/property was investigated by FTIR, NMR, XRD, Brunauer–Emmett–Teller (BET) etc. The obtained porous polymer exhibited a high surface area of 1015 m 2 g −1 and a hierarchical pore structure. It could be applied to wastewater treatment with the absorption capacity of up to 1683 mg g −1 for Congo red (CR), 1083 mg g −1 for crystal violet (CV), 1003 mg g −1 for rhodamine B (RB), 441 mg g −1 for methylene blue (MB), 191 mg g −1 for Hg 2+ , and 328 mg g −1 for Pb 2+ . Remarkably, it could be easily regenerated and the removal efficiency remains almost constant even after six cycles.
