Abstract
Disclosed herein are metal-organic frameworks (MOF) and uses thereof, including those comprising a repeat unit of the formula [Cu3(L1)2(H2O)3] or [Cu3(L2)2(H2O)3], wherein L1 is a ligand of the formula: (structurally represented), and where L2 is a ligand of the formula: (structurally represented). These are useful for many applications, including in the purification of hydrogen gas from production byproducts CH4 and CO2, sensing, heterogeneous catalysis, drug delivery, lithium sulfide battery, membrane and analytical devices.
Claims37
A metal-organic framework (MOF) comprising a repeat unit of the formula [Cu3(L1)2(H2O)3] or [Cu3(L2)2(H2O)3], wherein L1 is a ligand of the formula:
- and
- wherein L2 is a ligand of the formula:
A method of separating two or more compounds using an MOF comprising:
- (a) obtaining a MOF comprising a repeat unit of the formula [Cu3(L1)2(H2O)3] or [Cu3(L2)2(H2O)3], wherein L1 is a ligand of formula:
- and
- L2 is a ligand of formula:
- (b) combining the MOF with a mixture comprising a first compound and one or a group of second compounds;
- and
- (c) separating the two or more compounds based on their differential sorption rate within the MOF.
