Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>A three‐dimensional microporous anionic metal–organic framework (MOF) (Et₄N)₃[In₃(TATB)₄] (<bold>FJI‐C1</bold>, H₃TATB=4, 4′, 4′′‐<italic>s</italic>‐triazine‐2, 4, 6‐triyltribenzoic acid) with large unit cell volume has been synthesized. Assisted by the organic cation group Et₄N in the pores of the compound, <bold>FJI‐C1</bold> not only shows high adsorption uptakes of C₂ and C₃ hydrocarbons, but also exhibits highly selective separation of propane, acetylene, ethane, and ethylene from methane at room temperature. Furthermore, it also exhibits high separation selectivity for propane over C₂ hydrocarbons and acetylene can be readily separated from their C₂ hydrocarbons mixtures at low pressure due to the high selectivity for C₂H₂ in comparison to C₂H₄ and C₂H₆. In addition, <bold>FJI‐C1</bold> with hydrophilic internal pores surfaces shows highly efficient adsorption separation of polar molecules from nonpolar molecules. Notably, it exhibits high separation selectivity for benzene over cyclohexane due to the π–π interactions between benzene molecules and <italic>s</italic>‐triazine rings of the porous MOF.</p> </abstract>
