通过厄尔曼缩合反应合成了一种具有dia-c5拓扑结构的多孔聚苯醚JUC-Z6,并对其结构进行了表征.结果表明,该化合物具有高热稳定性(214℃失重5%)、高化学稳定性、高BET比表面积(192 m2/g)及窄孔径分布(1.36 nm).低压气体吸附测试结果表明,JUC-Z6在多孔材料中具有较高的吸附焓(氢气4.1 kJ/mol,二氧化碳33.7 kJ/mol,甲烷4.1 kJ/mol)。
A porous polyphenylene ether (JUC-Z6) with dia-c5 topology was synthesized by Ehrman condensation reaction and its structure was characterized.The results show that the compound has high thermal stability (214% weight loss 5%), High chemical stability, high BET specific surface area (192 m2 / g) and narrow pore size distribution (1.36 nm) .The results of low pressure gas adsorption test showed that JUC-Z6 has a higher adsorption enthalpy in porous materials (hydrogen 4.1 kJ / mol , 33.7 kJ / mol of carbon dioxide, 4.1 kJ / mol of methane).
