以二茂铁与卟啉衍生物为构筑单元,通过希夫碱偶合反应制备了二茂铁基多孔有机聚合物(FcPOP).系统表征了FcPOP的结构与形貌,FcPOP表现出良好的热稳定性、高孔隙率、微孔结构以及均匀的孔径分布.二茂铁单元具有高度富电子特性,赋予FcPOP优秀的CO2和甲基紫吸附能力.甲基紫吸附动力学研究表明,FcPOP对甲基紫的吸附符合准二级动力学模型.以Langmuir等温线模型计算,得到FcPOP的最大吸能力达到516 mg/g.更重要的是,FcPOP可被简单再生,再重复应用于高效除去印染废水中的甲基紫.总的来说,制备的FcPOP在气体捕获和印染废水处理领域中表现出良好的应用前景.
Ferrocene-based porous organic polymer (FcPOP) was constructed with ferrocene and porphyrin derivatives as building blocks via Schiff-base coupling. FcPOP was well characterized, and exhibited good thermal stability, high porosity, microporous structure, and homogeneous pore size distribution. Ferrocene blocks with highly electron-rich characteristics endowed FcPOP with excellent adsorption capacity of CO2 and methyl violet. The kinetic study indicated adsorption of methyl violet onto FcPOP mainly complied with pesudo-second order model. The maximum adsorption capacity of FcPOP derived from Langmuir isotherm model reached up to 516 mg/g. More importantly, FcPOP could be easily regenerated and repeatedly employed for removal of methyl violet with high efficiency. Overall, FcPOP in the present study highlighted prospective applications in the field of gas capture and dyeing wastewater treatment.
