Abstract
A metal-organic framework includes: a tetravalent Group 4 element ion or a tetravalent rare earth ion as a metal ion; and an ion of a first organic molecule having a trimesic acid skeleton and an ion of a second organic molecule having an isophthalic acid skeleton as multidentate ligands.
Claims18
A metal-organic framework comprising:
- a Zr4+ metal ion;
- and
- an ion of a first organic molecule having a trimesic acid skeleton and an ion of a second organic molecule having an isophthalic acid skeleton as multidentate ligands,
- wherein a proportion of the ion of the second organic molecule having the isophthalic acid skeleton is greater than or equal to 1.2 mol% and lower than 8.4 mol% with respect to all of the multidentate ligands.

A method of manufacturing a metal-organic framework, the method comprising:
- heating a solution including a zirconium compound which is a Zr4+ metal ion source, a first organic molecule having a trimesic acid skeleton or a salt of the first organic molecule having the trimesic acid skeleton, a second organic molecule having an isophthalic acid skeleton or a salt of the second organic molecule having the isophthalic acid skeleton, and a solvent to obtain the metal organic framework,
- wherein the metal-organic framework comprises:
- a Zr4+ metal ion;
- and
- an ion of the first organic molecule having the trimesic acid skeleton and an ion of the second organic molecule having the isophthalic acid skeleton as multidentate ligands, and
- wherein a proportion of the ion of the second organic molecule having the isophthalic acid skeleton is greater than or equal to 1.2 mol% and lower than 8.4 mol% with respect to all of the multidentate ligands.
