Abstract
Embodiments of the present disclosure describe a metal-organic framework (MOF) composition comprising a plurality of metal clusters, wherein the metal is chromium; and one or more tetratopic ligands; wherein the metal clusters and ligands associate to form a MOF with soc topology. A method of making a MOF comprising contacting a template MOF of formula Fe-soc-MOF and a reactant including chromium in a presence of dimethylformamide sufficient to replace Fe with Cr and form an exchanged MOF of formula Cr-soc-MOF. A method of sorbing water vapor comprising exposing a Cr-soc-MOF to an environment; and sorbing water vapor using the Cr-soc-MOF.
