Abstract
A molecular building block composition can include a metal ion component; and a ligand component including a core including at least one functional group associated with the metal ion component and the core.
Claims17
A metal organic framework (MOF) comprising:
- a plurality of polynuclear metal clusters, wherein at least one of the polynuclear metal clusters includes a rare earth metal;
- and
- a plurality of polydentate ligands each linking two or more of the polynuclear metal clusters;
- wherein the MOF has a ftw (For Twelve) or ftw-a topology, wherein the polydentate ligand is a square or quadrangular ligand.
1 more element
A method of making of metal organic framework (MOF) having a ftw or ftw-a topology comprising:
- contacting a rare earth metal ion component and a polydentate ligand to form a mixture;
- allowing the mixture to react whereby a crystalline metal organic framework with a ftw or ftw-a topology forms, wherein the polydentate ligand is a square or quadrangular ligand.
A method of separating a compound from a mixture of gases comprising:
- contacting a metal organic framework (MOF) having a ftw or ftw-a topology with a mixture of gases including at least one compound selected from the group consisting of H2, N2, O2, CO2, H2S, H2O, hydrocarbons, linear hydrocarbons, branching hydrocarbons, and aromatic hydrocarbons;
- and
- adsorbing the at least one compound in the MOF, thereby separating the compound from the mixture;
- wherein the MOF having a ftw or ftw-a topology comprises a plurality of polynuclear metal clusters, wherein at least one of the polynuclear metal clusters includes a rare earth metal;
- and a plurality of polydentate ligands each linking two or more of the polynuclear metal clusters wherein the plurality of polydentate ligands is a square or quadrangular ligand.
