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 g and a hierarchical pore structure. It could be applied to wastewater treatment with the absorption capacity of up to 1683 mg g for Congo red (CR), 1083 mg g for crystal violet (CV), 1003 mg g for rhodamine B (RB), 441 mg g for methylene blue (MB), 191 mg g for Hg , and 328 mg g for Pb . Remarkably, it could be easily regenerated and the removal efficiency remains almost constant even after six cycles.
一种新型的二茂铁连接的有机-无机杂化多孔聚合物通过辛基乙烯基倍半硅氧烷和二茂铁的傅克反应成功制备。通过 FTIR、NMR、XRD、BET 等方法研究了结构/性能的关系。所得多孔聚合物具有高达 1015 m2/g 的比表面积和分级孔结构。它可以应用于废水处理，对刚果红（CR）的吸附量高达 1683mg/g，对结晶紫（CV）的吸附量为 1083mg/g，对罗丹明 B（RB）的吸附量为 1003mg/g，对亚甲蓝（MB）的吸附量为 441mg/g，对汞（Hg）的吸附量为 191mg/g，对铅（Pb）的吸附量为 328mg/g。值得注意的是，它可以很容易地再生，即使经过六次循环，去除效率几乎保持不变。
