Abstract

Compositions comprising multivariate metal-organic frameworks and other single-linker metal-organic frameworks are used for containing and storing a gas or fluid or for water harvesting or water purification applications.

First claim

What is claimed is:

1 . A metal-organic framework (MOF), comprising repeating cores, wherein the cores comprise secondary building units connected to organic ligands,
wherein the secondary building units comprise one or more metals or metal-containing complexes, wherein the organic ligands comprise one or more linear ditopic moieties, v-shaped ditopic moieties, trigonal tritopic moieties, square or rectangular tetratopic moieties, or tetrahedral tetratopic moieties, wherein the moieties comprise 5-membered or 6-membered rings substituted with at least two carboxylate groups, and wherein the secondary building units are connected to the organic ligands through the oxygen atoms of the carboxylate groups in the organic ligands.

2 . The MOF of claim 1 , wherein the secondary building units form 1D rod-like chains or distinct multinuclear metal clusters.

3 . The MOF of claim 1 , wherein the organic ligands comprise one or more moieties of Formula (I)-(XII):

wherein X 1 is NH, O or S, and each of R a and R b is independently H or alkyl;

wherein X 3 is NH, O or S, and each of R a and R c is independently H or alkyl;

wherein X 2 is NH, O or S, and R c is H or alkyl;

wherein X 1 is NH, O or S, and R a is H or alkyl:

wherein X 3 is NH, O or S, and R a is H or alkyl;

wherein X 1 is NH, O or S;

wherein Y 1 , Y 2 and Y 3 are independently CH or N;

wherein X 3 is NH, O or S;

wherein Y 1 and Y 2 are independently CH or N;

wherein each of R d , R e and R f is independently H or alkyl;

wherein one of Y 1 and Y 4 is N, and the remaining of Y 4 and Y 1 is CH, or both Y 1 and Y 4 are N, and each of R d and R e are independently H or alkyl; and

wherein Y 1 is CH or N.

4 . The MOF of claim 3 , wherein R a , R b , R c , R d , R e and R f are each H.

5 . The MOF of claim 1 , wherein the organic ligands comprise one or more moieties:

6 . The MOF of claim 1 , wherein the MOF is a single-linker metal-organic framework.

7 . The MOF of claim 6 , wherein each organic ligand comprises:

8 . The MOF of claim 1 , wherein each secondary building unit comprises aluminum hydroxide.

9 . The MOF of claim 1 , wherein the MOF is MOF-313, MOF-314, or MOF-323.

10 . The MOF of claim 1 , wherein the MOF is a multivariate metal-organic framework (MTV-MOF).

11 . The MOF of claim 10 , wherein the organic ligands comprises a plurality of moieties of Formula (I)-(XII).

12 . The MOF of claim 11 , wherein the organic ligands comprises two moieties of Formula (I)-(XII).

13 . The MOF of claim 1 , wherein the MOF is Al(OH)(2,5-FDC) w (2,4-TDC) v , wherein w+v=1; or Al(OH)(3,5-PynDC) m (IPA) n , wherein m+n=1.

14 . The MOF of claim 1 , wherein each secondary building unit comprises zirconium, nickel, iron, copper, manganese, aluminum, magnesium, calcium, strontium, barium, titanium, zinc, indium, cadmium, hafnium, lead, cobalt, or chromium, or a complex thereof.

15 . The MOF of claim 1 , wherein each secondary building unit comprises aluminum or an aluminum-containing complex.

16 . The MOF of claim 1 , wherein the secondary building units form 1D rod-like chains, and the organic ligands comprise one or more v-shaped ditopic moieties.

17 . The MOF of claim 16 , wherein the secondary building units are connected to the organic ligands through the oxygen atoms of the carboxylate groups in the organic ligands via a cis-edge-shared octahedra geometry or a trans-edge-shared octahedra geometry.

18 . A method of water harvesting, comprising:
adsorbing water from ambient atmosphere using a water-harvesting system, wherein the water-harvesting system comprises one or more MOFs of claim 1 ; desorbing vapor from the one or more MOFs; and collecting water from the vapor using a condenser.

19 . A water harvesting system, comprising:
an adsorbent layer comprising one or more MOFs of claim 1 ; and a condenser adjacent to the adsorbent layer.

20 . The system of claim 19 , wherein the system is a passive water harvesting system.
