摘要：

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).

Abstract:

A poly(phenyl ether), JUC-Z6, with dia-c5 topology was designed and synthesized with cheap reactants tetrakis(4-bromophenyl)methane and hydroquinone via Goldberg modified Ullmann biaryl ether condensation reaction. JUC-Z6 was determined by MAS NMR, FTIR, SEM, TEM and PXRD. The functional structure exhibits not only high thermal stability (214℃) and high chemical stability, but also large surface area(191 m2/g), and the pore size is 1.36 nm. Low pressure gas uptake experiments on activated JUC-Z6 show high heat of sorption (Qst=4.1 kJ/mol for hydrogen, Qst=33.7 kJ/mol for carbon dioxide and Qst=4.1 kJ/mol for methane) among porous materials.

Key words: Porous organic framework(POF), Ullmann reaction, Gas storage, Poly(phenyl ether), Carbon capture
