Multiple phase-transitions upon selective CO2 adsorption in an alkyl ether functionalized metal–organic framework—an in situ X-ray diffraction study

Abstract

The flexible alkyl ether functionalized metal–organic framework [Zn2(BME-bdc)2(dabco)]n (BME-bdc = 2,5-bis(2-methoxyethoxy)-1,4-benzenedicarboxylate, dabco = 1,4-diazabicyclo[2.2.2]octane) shows remarkable structural changes upon selective adsorption of CO2 as determined by in situ X-ray diffraction at 195 K. Upon accommodation of carbon dioxide [Zn2(BME-bdc)2(dabco)]n transfers from a narrow pore form to an open pore form, which exhibits a much higher unit cell volume. Due to the slow adsorption kinetics an unexpected metastable intermediate form could be identified.
