Abstract

Official abstract text for this publication.

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.

First claim

Opening claim text (preview).

What is claimed is: 1. 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. 2. The MOF of claim 1 , wherein the polydentate ligand is selected from the group consisting of 3,3″,5,5″-tetrakis(4-carboxyphenyl)-p-terphenyl, 3′,3″,5′,5″-tetrakis(4-carboxyphenyl)-1.4-diphenylnaphthalene, 3′,3″,5′,5″-tetrakis(4-carboxyphenyl)-9,10-diphenylanthracene, 3,3″,5′,5″-tetra-2-(4-carboxyphenyl)ethynyl-p-terphenyl, and 4,4′,4″,4′″-((benzene-1,2,4,5-tetrayltetrakis(methylene))tetrakis(oxy))tetrabenzoic acid. 3. The MOF of claim 1 , wherein the polynuclear cluster is a cuboctahedral 12-c molecular building block (MBB). 4. The MOF of claim 1 , wherein the rare earth metal is selected from yttrium, ytterbium, terbium, and combinations thereof. 5. The MOF of claim 1 , wherein the MOF has a (1, 12) or (4, 12) connectivity. 6. 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. 7. The method of claim 6 , wherein the mixture further comprises a reaction modulator. 8. The method of claim 7 , wherein the reaction modulator is F-Benzoic acid. 9. The method of claim 6 , wherein the polydentate ligand is selected from the group consisting of 3,3″,5,5″-tetrakis(4-carboxyphenyl)-p-terphenyl, 3′,3″,5′,5″-tetrakis(4-carboxyphenyl)-1,4-diphenylnaphthalene, 3 ‘,3 “,5’,5”-tetrakis (4-carboxyphenyl)-9, 1 0-diphenylanthracene, 3,3″,5,5″-tetra-2-(4-carboxyphenyl)ethynyl-p-terphenyl, and 4,4′,4″,4′″-((benzene-1,2,4,5-tetrayltetrakis(methylene))tetrakis(oxy))tetrabenzoic acid. 10. The method of claim 6 , wherein the mixture further comprises a solvent. 11. The method of claim 6 , wherein the rare earth metal ion component forms a 12-c molecular building block (MBB) represented by a formula M 6 (OH) 8 L 12 , where M is the rare earth metal and L is the polydentate ligand. 12. The method of claim 6 , wherein the rare earth metal is selected from yttrium, ytterbium, terbium, and combinations thereof. 13. 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 H 2 , N 2 , O 2 , CO 2 , H 2 S, H 2 O, 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. 14. The method of claim 13 , wherein the polydentate ligand is selected from the group consisting of 3,3″,5,5″-tetrakis(4-carboxyphenyl)-p-terphenyl, 3′,3″,5′,5″-tetrakis(4-carboxyphenyl)-1,4-diphenylnaphthalene, 3′,3″,5′,5″-tetrakis(4-carboxyphenyl)-9,10-diphenylanthracene, 3,3″,5,5″-tetra-2-(4-carboxyphenyl)ethynyl-p-terphenyl, and 4,4′,4″,4′″-((benzene-1,2,4,5-tetrayltetrakis(methylene))tetrakis(oxy))tetrabenzoic acid. 15. The method of claim 13 , wherein the polynuclear cluster is a cuboctahedral 12-c molecular building block (MBB). 16. The method of claim 13 , wherein the rare earth metal is selected from yttrium, ytterbium, terbium, and combinations thereof. 17. The method of claim 13 , wherein the MOF has a (1,12) or (4,12) connectivity.
