Abstract
Official abstract text for this publication.
Embodiments of the present disclosure describe compositions comprising a molecular building block (MBB) having the formula [RE 6 (μ 3 -OH) 8 (O 2 C—) 6 N 4 C—) 6 ] or [RE 6 (μ 3 -OH) 8 (O 2 C—) 12 ], wherein RE is a rare earth metal ion. Embodiments of the present disclosure further describe methods of making a metal-organic framework (MOF) composition comprising contacting one or more molecular building blocks (MBBs) with one or more bidentate ligands, wherein the MBBs have the formula [RE 6 (μ 3 -OH) 8 (O 2 C—) 6 N 4 C—) 6 ] or [RE 6 (μ 3 -OH) 8 (O 2 C—) 12 ], wherein RE is a rare earth metal ion.
First claim
Opening claim text (preview).
What is claimed is: 1. A composition, comprising: a molecular building block (MBB) having the formula [RE 6 (μ 3 -OH) 8 (O 2 C—) 12 ], wherein RE is a rare earth metal ion. 2. The composition of claim 1 , wherein the rare earth metal ion is selected from cerium, dysprosium, erbium, europium, gadolinium, holmium, lanthanum, lutetium, neodymium, praseodymium, promethium, samarium, scandium, terbium, thulium, ytterbium, yttrium, and combinations thereof. 3. The composition of claim 1 , further comprising a bidentate ligand. 4. The composition of claim 3 , wherein the bidentate ligand includes one or more of carboxylates, trizolates, tetrazolates, pyrazolates, and fluoros. 5. The composition of claim 4 , wherein the carboxylates are dicarboxylates. 6. The composition of claim 4 , wherein the trizolates are ditrizolates. 7. The composition of claim 4 , wherein the tetrazolates are ditetrazolates. 8. The composition of claim 4 , wherein the pyrazolates are dipyrazolates. 9. The composition of claim 3 , wherein the bidentate ligand is 2-fluoro-4-(1H-tetrazol-5-yl)benzoate (FTZB), 4-(1H-tetrazol-5-yl)benzoate (TZB), 3-fluoro-4′-(2H-tetrazol-5-yl)biphenyl-4-carboxylate (FTZBP), 3-fluorobiphenyl-4,4′-dicarboxylate (FBPDC), or 3,3′-difluorobiphenyl-4,4′-dicarboxylate (DFBPDC). 10. A method of making a metal-organic framework (MOF) composition, comprising: contacting one or more molecular building blocks (MBBs) with one or more bidentate ligands, wherein the MBBs have the formula [RE 6 (μ 3 -OH) 8 (O 2 C—) 12 ], wherein RE is a rare earth metal ion. 11. The method of claim 10 , wherein the rare earth metal ion is selected from cerium, dysprosium, erbium, europium, gadolinium, holmium, lanthanum, lutetium, neodymium, praseodymium, promethium, samarium, scandium, terbium, thulium, ytterbium, yttrium, and combinations thereof.
