摘要
共价有机框架材料(Covalent Organic Frameworks,COFs)作为一类新型的多孔材料对生物小分子具有良好的吸附性能,作为吸附剂广泛应用于污染物吸附.基于菲并咪唑三胺和间苯二甲醛为单体,通过缩合反应,采用溶剂热法"自下而上"合成以亚胺键链接的菲并咪唑共价有机框架(PIP-B COF)材料.通过傅里叶红外光谱(FT-IR)、X光电子能谱(XPS)、X射线衍射(XRD)和扫描电镜(SEM)等对合成的PIP-B COF材料结构进行了确认和表征.以PIP-B COF材料作为吸附剂,验证了其对固体碘蒸汽和环己烷溶液中碘的吸附性能.结果表明,PIP-B COF材料对固体碘蒸汽和液相溶液中的碘均表现出优异的吸附性能,并可以实现循环使用,在现实水样检测中具有潜在的应用价值.
Abstract
Covalent Organic Frameworks(COFs)as an emergent category of porous materials are renowned due to their exceptional adsorption capabilities towards biological small molecules and are extensively applied in removing pollutants as adsorbents.Amine COF(PIP-B COF)was synthesized with phenanthro[9,10-d]imidazole triamine and terephthalaldehyde as monomers through a solvothermal"bottom-up"approach and its structure was characterized and confirmed by fourier transform infrared spectroscopy(FT-IR),X-ray photoelectron spectroscopy(XPS),X-ray diffraction(XRD)and scanning electron microscope(SEM).The adsorption properties of solid-state iodine vapor and iodine in a cyclohexane solution was evaluated with PIP-B COF as adsorbent.The results suggest that PIP-B COF possesses superior adsorption properties for iodine in both the solid and liquid phases,and exhibits the remarkable recyclability,hinting the potential application in real water detection.
