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
