Abstract
Compositions comprising multivariate metal-organic frameworks and other single-linker metal-organic frameworks are used for containing and storing a gas or fluid or for water harvesting or water purification applications.
Claims20
A metal-organic framework (MOF) composition, comprising repeating cores, wherein the cores comprise secondary building units connected to organic ligands,
- wherein the secondary building units comprise one or more metals or metal-containing complexes,
- wherein the organic ligands comprise one or more linear ditopic moieties, v-shaped ditopic moieties, trigonal tritopic moieties, square or rectangular tetratopic moieties, or tetrahedral tetratopic moieties, wherein the moieties comprise 5-membered or 6-membered rings substituted with at least two carboxylate groups, and
- wherein the secondary building units are connected to the organic ligands through the oxygen atoms of the carboxylate groups in the organic ligands;
- wherein the organic ligands comprise one or more moieties of the following:
- wherein each secondary building unit comprises aluminum hydroxide.
