Abstract
Methods of preparing and using a metal-organic framework (MOF) are provided herein, including methods of using an MOF comprising a repeat unit of the formula [ML]n, wherein M is a divalent metal ion and L is a ligand of the formula: The MOFs provided herein may be used in the separation of two or more molecules from each other. In some embodiments, the molecules are ethylene and ethane. In some embodiments, UTSA-280 may be synthesized from calcium oxide (CaO) or calcium hydroxide (Ca(OH)2) and squaric acid (SA) through mechanochemical synthesis.
