通过傅氏烷基化反应成功地合成了基于四苯锗烷构筑单元的多孔有机骨架材料PAF-9。用红外光谱,粉末X射线衍射,固体核磁共振,热重分析和低温氮气吸附-脱附表征了PAF-9材料的微结构与孔道性质。表征数据表明PAF-9具有非常高的热稳定性和化学稳定性,同时具有较高的比表面积。该PAF材料的BET比表面积为334 m2·g-1。此外,得到的PAF材料对二氧化碳具有较好的吸附能力。
The porous organic framework material PAF-9 based on tetrabenane germane structure was successfully synthesized by Friedel-Crafts reaction. The microstructure and pore properties of PAF-9 were characterized by FTIR, powder X-ray diffraction, solid state nuclear magnetic resonance, thermogravimetric analysis and low temperature nitrogen adsorption-desorption. Characterization data show that PAF-9 has very high thermal stability and chemical stability, while having a high specific surface area. The PAF material has a BET specific surface area of 334 m2 · g-1. In addition, the resulting PAF material has good adsorption capacity for carbon dioxide.
