Isoreticular metal-organic framework of the formula Zn
View Patent ↗This invention provides metal-organic frameworks (MOFs) having repeat units of the formula Zn 4 O(fumarate) 3 . Also provided are compositions thereof and methods use thereof, including for gas storage, gas separation, catalysis and sensing.
1. A metal-organic framework (MOF) comprising a repeat unit of the formula Zn 4 O(fumarate) 3 .
2. The MOF of claim 1 , further comprising one or more solvent molecules.
3. The MOF of claim 2 , where one or more of the solvent molecules are independently selected from the group consisting of N,N′-dimethylformamide, N,N′-dimethylformamide and ethanol.
4. The MOF of claim 1 , substantially free from any solvent molecules.
5. The MOF of claim 1 having a weight percentage at least 90% attributable to repeat units of the formula Zn 4 O(fumarate) 3 .
6. The MOF of claim 1 having a weight percentage at least 95% attributable to repeat units of the formula Zn 4 O(fumarate) 3 .
7. The MOF of claim 1 having a weight percentage at least 99% attributable to repeat units of the formula Zn 4 O(fumarate) 3 .
8. A method of storing a gas comprising:
(a) obtaining a metal-organic framework (MOF) comprising a repeat unit of the formula Zn 4 O(fumarate) 3 ;
(b) combining the MOF with a gas.
9. The method of claim 8 , where the MOF further comprises one or more solvent molecules.
10. The method of claim 9 , where one or more of the solvent molecules are independently selected from the group consisting of N,N′-dimethylformamide, N,N′-dimethylformamide and ethanol.
11. The method of claim 8 , where the MOF has a weight percentage at least 90% attributable to repeat units of the formula Zn 4 O(fumarate) 3 .
12. The method of claim 8 , where the MOF has a weight percentage at least 95% attributable to repeat units of the formula Zn 4 O(fumarate) 3 .
13. The method of claim 8 , where the MOF has a weight percentage at least 99% attributable to repeat units of the formula Zn 4 O(fumarate) 3 .
