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.

First claim

What is claimed is:

1. A metal organic framework, comprising:
a plurality of polynuclear metal clusters; and a plurality of polydentate ligands each linking to two or more of the polynuclear metal clusters; wherein at least one of the plurality of polydentate ligands is a triangular ligand,
wherein the polynuclear metal cluster includes at least seven metal ions and 8 to 18 points of extension.

2. The metal organic framework of claim 1 , wherein the polynuclear metal clusters comprise one or more lanthanide metals.

3. The metal organic framework of claim 1 , wherein the polynuclear metal clusters comprise one or more transition metals.

4. The metal organic framework of claim 1 , wherein the polynuclear metal clusters comprise one or more of Yttrium, Lanthanum, Cerium, Praseodymium, Neodymium, Samarium, Europium, Gadolinium, Terbium, Dysprosium, Holmium, Erbium, Thulium, Ytterbium, Scandium and Lutetium.

5. The metal organic framework of claim 1 , wherein the triangular ligand is selected from the group consisting of 1,3,5-benzene(tris)benzoate, biphenyl-3,4,5-tricarboxylic acid, 9-(4-carboxyphenyl)-9H-carbazole-3,6-dicarboxylic acid, 5-(4-carboxybenzyloxy)-isophthalic acid, and 5′,5″′-((5-((4-(3,6-dicarboxy-9H-carbazol-9-yl)phenyl)ethynyl)-1,3-phenylene)bis(ethyne-2,1-diyl)bis([1,1′:3′,1″-terphenyl]-4,4″-dicarboxylic acid).

6. The metal organic framework of claim 1 , wherein the polynuclear metal clusters are in contact with a fluorinated group.

7. The metal organic framework of claim 1 , wherein the at least one triangular ligand binds the at least two polynuclear metal clusters at angles of 90°, 120°, or a combination thereof.

8. The metal organic framework of claim 1 , wherein at least one of the coordinating groups in the plurality of ligands comprises a carboxylate, tetrazole, triazole, or sulfonate.

9. The metal organic framework of claim 1 , wherein at least one of the plurality of metal polynuclear clusters is a nonanuclear metal cluster or a metal-organic polyhedron comprising nine copper paddlewheels.

10. The metal organic framework of claim 9 , wherein at least one of the polynuclear metal clusters is the metal-organic polyhedron comprising nine copper paddlewheels.

11. The metal organic framework of claim 10 , wherein the polynuclear metal cluster comprises 18 bridging ligands.

12. The metal organic framework of claim 11 wherein the metal-organic polyhedron comprises bridging ligands selected from the group consisting of 4,4′-(pyridine-,6-diyl) dibenzoic acid, carbazole-3,6-dicarboxylic acid, and combinations thereof.

13. The metal organic framework of claim 11 , wherein the triangular ligand is a hexacarboxylate ligand.

14. The metal organic framework of claim 9 , wherein at least one nonanuclear cluster is present.

15. The metal organic framework of claim 14 , wherein the at least one nonanuclear cluster has 18 points of extension.

16. The metal organic framework of claim 14 , further comprising at least one hexanuclear metal cluster, wherein the at least one nonanuclear metal cluster has 12 points of extension.
