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 m(2) 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 Si-OH groups in the pore structures. The porous polymer can be modified by the reaction of Si-OH 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.
