Abstract
A novel hyper-cross-linked porous polymer based on hexaphenyldisiloxane (HCP-DH) is synthesized through Friedel−Crafts reaction. The surface area of HCP-DH is up to 1084 m2 g−1, and it exhibits excellent adsorption capacities and reusability in organic dyes removal from water. Additionally, the structure of the synthesized polymer can be adjusted by alkali treatment, forming SiOH groups in the pore structures. The porous polymer can be modified by the reaction of SiOH groups and (3-aminopropyl)methyldiethoxysilane easily, and the amino functionalized porous polymer displays a good property in the field of chromium ion adsorption with an adsorption amount of 44.5 mg g−1 under neutral condition. This method provides a new strategy for the synthesis and functionalization of porous polymers.
