Abstract
A method produces a metal-organic framework on a surface of another metal-organic framework. One embodiment comprises contacting the first metal-organic framework with a ligand and solvent solution; wherein the first metal-organic framework comprises a first ligand and a first metal; wherein the ligand and solvent solution comprises a second ligand that is different from the first ligand in the first metal-organic framework; and allowing the second ligand from the ligand and solvent solution to exchange with the first ligand present in the first metal-organic framework for a period of time suitable to produce the second metal-organic framework on the surface of the first metal-organic framework.
Claims7
A method for producing a second metal-organic framework on a surface of a first metal-organic framework comprising:
- (A) contacting the first metal-organic framework with a ligand and solvent solution;
- wherein the first metal-organic framework comprises a first ligand and a first metal;
- wherein the ligand and solvent solution comprises a second ligand that is different from the first ligand in the first metal-organic framework;
- and
- (B) allowing the second ligand from the ligand and solvent solution to exchange with the first ligand present in the first metal-organic framework for a period of time suitable to produce the second metal-organic framework on the surface of the first metal-organic framework.
