利用次级结构基块构筑的多孔芳香骨架材料
摘要：
一种利用次级结构基块构筑的多孔芳香骨架材料PAF‑100和PAF‑101，属于多孔芳香骨架材料制备技术领域。在催化剂作用下，1,4‑双((三(4‑溴苯基)硅基)苯或者4,4’‑双((三(4‑溴苯基)硅基)联苯作为反应物自身发生聚合反应，得到PAF‑100和PAF‑101。热重分析表明PAF‑100和PAF‑101的热分解温度超过500℃，它们具有高的热稳定性。通过N2吸附‑脱附表征，PAF‑100的BET比表面积达到4990m2/g；PAF‑101的BET比表面积达到5114m2/g。合成的聚合物具有显著的多孔性和良好的稳定性，具有广阔的应用前景，本发明为有机多孔材料的合成提供了一种新颖的思路。
摘要（英）：

The invention relates to porous aromatic framework materials PAF-100 and PAF-101 constructed by utilizing a secondary structure base block and belongs to the technical field of preparation of porous aromatic framework materials. Under the action of a catalyst, 1,4-bis ((tris(4-bromophenyl) silyl) benzene or 4,4'-bis ((tris(4-bromophenyl) silyl) biphenyl) are subjected to self polymerization reaction as reactants to obtain the PAF-100 and the PAF-101. Thermogravimetric analysis shows that when the thermal decomposition temperature of each of the PAF-100 and the PAF-101 exceeds 500 DEG C, each of the PAF-100 and the PAF-101 has high heat stability. N2 adsorption-desorption characterizes that the BET specific surface area of the PAF-100 reaches 4990 m<2>/g, and the BET specific surface area of the PAF-101 reaches 5114 m<2>/g. A synthetic polymer has remarkable porosity, good stability and wide application prospect; the invention provides a novel idea for the synthesis of the organic porous materials.
