Abstract
A hydrogen-bonded organic framework (HOF) and a method of making the HOF. The HOF has at least one amine substituted organic linker and at least one carboxylic acid-based organic linker. The HOF is prepared by dissolving the linkers separately in water and mixing the aqueous solutions, without using any organic solvents, additional catalysts, or any other reagents.
Claims20
A one-pot method of making a hydrogen-bonded organic framework (HOF), comprising:
- dissolving trimesic acid in water at a temperature greater than 60° C. to form a first solution;
- dissolving an aromatic compound in water to form a second solution wherein the aromatic compound is substituted with at least two amine groups;
- adding dropwise the second solution into the first solution at a temperature greater than 60° C. to form a synthetic solution;
- cooling the synthetic solution to below 50° C. forming a precipitate;
- and
- separating and drying the precipitate at a temperature of at least 60° C. to yield the HOF;
- wherein the first and second solutions do not comprise an organic solvent.
