Abstract

The study describes the synthesis of two porous hybrid polymers (abbreviated as DPPF-HPP and DPPOF-HPP) from the Friedel–Crafts reaction of octavinylsilsesquioxane with 1,1′-bis(diphenylphosphine)ferrocene (DPPF) and 1,1′-bis(diphenylphosphine oxide)ferrocene (DPPOF), respectively. DPPF-HPP and DPPOF-HPP possess surface areas of about 890 and 780 m2 g–1, respectively, as well as similar pore structures of the coexisting micropores and mesopores. They are excellent materials for high adsorption of different dyes with adsorption capacities of 2280 mg g–1 for Congo Red and 1440 mg g–1 for Crystal Violet. DPPF-HPP also shows a strong affinity to adsorb Hg2+ ions (300 mg g–1). These materials show no sign of degradation under repeated cycles and thus offer potential for wastewater treatment.
